pipe: fix poll/select race introduced by the pipe rework
The kernel wait queues have a basic rule to them: you add yourself to
the wait-queue first, and then you check the things that you're going to
wait on. That avoids the races with the event you're waiting for.
The same goes for poll/select logic: the "poll_wait()" goes first, and
then you check the things you're polling for.
Of course, if you use locking, the ordering doesn't matter since the
lock will serialize with anything that changes the state you're looking
at. That's not the case here, though.
So move the poll_wait() first in pipe_poll(), before you start looking
at the pipe state.

nfsd: depend on CRYPTO_MD5 for legacy client tracking
The legacy client tracking infrastructure of nfsd makes use of MD5 to
derive a client's recovery directory name. As the nfsd module doesn't
declare any dependency on CRYPTO_MD5, though, it may fail to allocate
the hash if the kernel was compiled without it. As a result, generation
of client recovery directories will fail with the following error:
NFSD: unable to generate recoverydir name

Merge branch 'tcp-fix-handling-of-stale-syncookies-timestamps'
Guillaume Nault says:
====================
tcp: fix handling of stale syncookies timestamps
The synflood timestamps (->ts_recent_stamp and ->synq_overflow_ts) are
only refreshed when the syncookie protection triggers. Therefore, their
value can become very far apart from jiffies if no synflood happens for
a long time.
If jiffies grows too much and wraps while the synflood timestamp isn't
refreshed, then time_after32() might consider the later to be in the
future. This can trick tcp_synq_no_recent_overflow() into returning
erroneous values and rejecting valid ACKs.
Patch 1 handles the case of ACKs using legitimate syncookies.
Patch 2 handles the case of stray ACKs.
Patch 3 annotates lockless timestamp operations with READ_ONCE() and
WRITE_ONCE().
Changes from v3:
- Fix description of time_between32() (found by Eric Dumazet).
- Use more accurate Fixes tag in patch 3 (suggested by Eric Dumazet).
Changes from v2:
- Define and use time_between32() instead of a pair of
time_before32/time_after32 (suggested by Eric Dumazet).
- Use 'last_overflow - HZ' as lower bound in
tcp_synq_no_recent_overflow(), to accommodate for concurrent
timestamp updates (found by Eric Dumazet).
- Add a third patch to annotate lockless accesses to .ts_recent_stamp.
Changes from v1:
- Initialising timestamps at socket creation time is not enough
because jiffies wraps in 24 days with HZ=1000 (Eric Dumazet).
Handle stale timestamps in tcp_synq_overflow() and
tcp_synq_no_recent_overflow() instead.
- Rework commit description.
- Add a second patch to handle the case of stray ACKs.

tcp: Protect accesses to .ts_recent_stamp with {READ,WRITE}_ONCE()
Syncookies borrow the ->rx_opt.ts_recent_stamp field to store the timestamp of the last synflood. Protect them with READ_ONCE() and WRITE_ONCE() since reads and writes aren't serialised. Use of .rx_opt.ts_recent_stamp for storing the synflood timestamp was introduced by |

tcp: tighten acceptance of ACKs not matching a child socket
When no synflood occurs, the synflood timestamp isn't updated. Therefore it can be so old that time_after32() can consider it to be in the future. That's a problem for tcp_synq_no_recent_overflow() as it may report that a recent overflow occurred while, in fact, it's just that jiffies has grown past 'last_overflow' + TCP_SYNCOOKIE_VALID + 2^31. Spurious detection of recent overflows lead to extra syncookie verification in cookie_v[46]_check(). At that point, the verification should fail and the packet dropped. But we should have dropped the packet earlier as we didn't even send a syncookie. Let's refine tcp_synq_no_recent_overflow() to report a recent overflow only if jiffies is within the [last_overflow, last_overflow + TCP_SYNCOOKIE_VALID] interval. This way, no spurious recent overflow is reported when jiffies wraps and 'last_overflow' becomes in the future from the point of view of time_after32(). However, if jiffies wraps and enters the [last_overflow, last_overflow + TCP_SYNCOOKIE_VALID] interval (with 'last_overflow' being a stale synflood timestamp), then tcp_synq_no_recent_overflow() still erroneously reports an overflow. In such cases, we have to rely on syncookie verification to drop the packet. We unfortunately have no way to differentiate between a fresh and a stale syncookie timestamp. In practice, using last_overflow as lower bound is problematic. If the synflood timestamp is concurrently updated between the time we read jiffies and the moment we store the timestamp in 'last_overflow', then 'now' becomes smaller than 'last_overflow' and tcp_synq_no_recent_overflow() returns true, potentially dropping a valid syncookie. Reading jiffies after loading the timestamp could fix the problem, but that'd require a memory barrier. Let's just accommodate for potential timestamp growth instead and extend the interval using 'last_overflow - HZ' as lower bound.

tcp: fix rejected syncookies due to stale timestamps
If no synflood happens for a long enough period of time, then the
synflood timestamp isn't refreshed and jiffies can advance so much
that time_after32() can't accurately compare them any more.
Therefore, we can end up in a situation where time_after32(now,
last_overflow + HZ) returns false, just because these two values are
too far apart. In that case, the synflood timestamp isn't updated as
it should be, which can trick tcp_synq_no_recent_overflow() into
rejecting valid syncookies.
For example, let's consider the following scenario on a system
with HZ=1000:
* The synflood timestamp is 0, either because that's the timestamp
of the last synflood or, more commonly, because we're working with
a freshly created socket.
* We receive a new SYN, which triggers synflood protection. Let's say
that this happens when jiffies == 2147484649 (that is,
'synflood timestamp' + HZ + 2^31 + 1).
* Then tcp_synq_overflow() doesn't update the synflood timestamp,
because time_after32(2147484649, 1000) returns false.
With:
- 2147484649: the value of jiffies, aka. 'now'.
- 1000: the value of 'last_overflow' + HZ.
* A bit later, we receive the ACK completing the 3WHS. But
cookie_v[46]_check() rejects it because tcp_synq_no_recent_overflow()
says that we're not under synflood. That's because
time_after32(2147484649, 120000) returns false.
With:
- 2147484649: the value of jiffies, aka. 'now'.
- 120000: the value of 'last_overflow' + TCP_SYNCOOKIE_VALID.
Of course, in reality jiffies would have increased a bit, but this
condition will last for the next 119 seconds, which is far enough
to accommodate for jiffie's growth.
Fix this by updating the overflow timestamp whenever jiffies isn't
within the [last_overflow, last_overflow + HZ] range. That shouldn't
have any performance impact since the update still happens at most once
per second.
Now we're guaranteed to have fresh timestamps while under synflood, so
tcp_synq_no_recent_overflow() can safely use it with time_after32() in
such situations.
Stale timestamps can still make tcp_synq_no_recent_overflow() return
the wrong verdict when not under synflood. This will be handled in the
next patch.
For 64 bits architectures, the problem was introduced with the
conversion of ->tw_ts_recent_stamp to 32 bits integer by commit

lpc_eth: kernel BUG on remove
We may have found a bug in the nxp/lpc_eth.c driver. The function platform_set_drvdata() is called twice, the second time it is called, in lpc_mii_init(), it overwrites the struct net_device which should be at pdev->dev->driver_data with pldat->mii_bus. When trying to remove the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will return the pldat->mii_bus pointer and try to use it as a struct net_device pointer. This causes unregister_netdev to segfault and generate a kernel BUG. Is this reproducible?

tcp: md5: fix potential overestimation of TCP option space
Back in 2008, Adam Langley fixed the corner case of packets for flows
having all of the following options : MD5 TS SACK
Since MD5 needs 20 bytes, and TS needs 12 bytes, no sack block
can be cooked from the remaining 8 bytes.
tcp_established_options() correctly sets opts->num_sack_blocks
to zero, but returns 36 instead of 32.
This means TCP cooks packets with 4 extra bytes at the end
of options, containing unitialized bytes.

Merge branch 'net-tc-indirect-block-relay'
John Hurley says: ==================== Ensure egress un/bind are relayed with indirect blocks On register and unregister for indirect blocks, a command is called that sends a bind/unbind event to the registering driver. This command assumes that the bind to indirect block will be on ingress. However, drivers such as NFP have allowed binding to clsact qdiscs as well as ingress qdiscs from mainline Linux 5.2. A clsact qdisc binds to an ingress and an egress block. Rather than assuming that an indirect bind is always ingress, modify the function names to remove the ingress tag (patch 1). In cls_api, which is used by NFP to offload TC flower, generate bind/unbind message for both ingress and egress blocks on the event of indirectly registering/unregistering from that block. Doing so mimics the behaviour of both ingress and clsact qdiscs on initialise and destroy. This now ensures that drivers such as NFP receive the correct binder type for the indirect block registration. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

net: sched: allow indirect blocks to bind to clsact in TC
When a device is bound to a clsact qdisc, bind events are triggered to
registered drivers for both ingress and egress. However, if a driver
registers to such a device using the indirect block routines then it is
assumed that it is only interested in ingress offload and so only replays
ingress bind/unbind messages.
The NFP driver supports the offload of some egress filters when
registering to a block with qdisc of type clsact. However, on unregister,
if the block is still active, it will not receive an unbind egress
notification which can prevent proper cleanup of other registered
callbacks.
Modify the indirect block callback command in TC to send messages of
ingress and/or egress bind depending on the qdisc in use. NFP currently
supports egress offload for TC flower offload so the changes are only
added to TC.

net: core: rename indirect block ingress cb function
With indirect blocks, a driver can register for callbacks from a device
that is does not 'own', for example, a tunnel device. When registering to
or unregistering from a new device, a callback is triggered to generate
a bind/unbind event. This, in turn, allows the driver to receive any
existing rules or to properly clean up installed rules.
When first added, it was assumed that all indirect block registrations
would be for ingress offloads. However, the NFP driver can, in some
instances, support clsact qdisc binds for egress offload.
Change the name of the indirect block callback command in flow_offload to
remove the 'ingress' identifier from it. While this does not change
functionality, a follow up patch will implement a more more generic
callback than just those currently just supporting ingress offload.

- ZONE_DMA32 initialisation fix when memblocks fall entirely within the first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4). - Couple of ftrace fixes following the FTRACE_WITH_REGS patchset. - access_ok() fix for the Tagged Address ABI when called from from a kernel thread (asynchronous I/O): the kthread does not have the TIF flags of the mm owner, so untag the user address unconditionally. - KVM compute_layout() called before the alternatives code patching. - Minor clean-ups. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl3qdr8ACgkQa9axLQDI XvEKNA/9FWyqesV612qaFkhTFCg0f6byLP4wQf0ZqcZf74L5J6zeUCIc7Mqgdno3 jWROZNAW69gOYfwHxcBNyPVBpbAcx3k3WBBRWRJPnnJmeQk0oBLVdRziqdGKLxfw GhhWGsndnpxDOmyBJOWxZLemZjKFqYX3dhQ9Zi6pvkZgAeFEtIESw6S/iqf42nWL 1o/LgyQ5kjR6eto1OVW9QOQ83/TlXXlbsvoNwNFGghX1yHjQ6mZ3LITbiFdrbFlT FLLwsqlsPzDQcKagszTEHZTbXBf0RojKXWh3HKSEnmPwpacestvLJcKHTD9mtDmY Z+rLfyiolZmXoNU9LT6uGTzVD4cRWfzz6eHSYHiufM1UztGSV+dOhIqfPuEOLEu3 2Xf8sKmQMtuICgbol6Q6ISrjXKH/UNvK2CuuuJSNmOHDlyHKvNfJtoyEhZ5rHUpT HQy0qxDCEU7rFCP7clOD/94EGA8gYrV8j5NauY8/VsLpRCMBwoLNglI049qJydaZ jL9dPxo+GG7kh7S8VmYwBKtPhqlDNFCzw/HmBBURFhkM1j0nCNt5dKHx+kdLNurg nbzRvJ+W42eDze2lmVf33eOfrAy2MfcGr+VuJ5QdmL30bQENCemPrreIy+VnVVR8 ydeK3lyknJjmX4q8a5o/URsAKvk13crwimNPa0OSoYzDKmWd8SA= =vhnZ -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - ZONE_DMA32 initialisation fix when memblocks fall entirely within the first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4). - Couple of ftrace fixes following the FTRACE_WITH_REGS patchset. - access_ok() fix for the Tagged Address ABI when called from from a kernel thread (asynchronous I/O): the kthread does not have the TIF flags of the mm owner, so untag the user address unconditionally. - KVM compute_layout() called before the alternatives code patching. - Minor clean-ups. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: entry: refine comment of stack overflow check arm64: ftrace: fix ifdeffery arm64: KVM: Invoke compute_layout() before alternatives are applied arm64: Validate tagged addresses in access_ok() called from kernel threads arm64: mm: Fix column alignment for UXN in kernel_page_tables arm64: insn: consistently handle exit text arm64: mm: Fix initialisation of DMA zones on non-NUMA systems |

This is needed on powerpc because we use asm-generic/bitops/non-atomic.h, for the non-atomic bitops, whereas the existing KASAN instrumented bitops assume all the underlying operations are provided by the arch as arch_foo() versions.

smb3: fix mode passed in on create for modetosid mount option
When using the special SID to store the mode bits in an ACE (See http://technet.microsoft.com/en-us/library/hh509017(v=ws.10).aspx) which is enabled with mount parm "modefromsid" we were not passing in the mode via SMB3 create (although chmod was enabled). SMB3 create allows a security descriptor context to be passed in (which is more atomic and thus preferable to setting the mode bits after create via a setinfo). This patch enables setting the mode bits on create when using modefromsid mount option. In addition it fixes an endian error in the definition of the Control field flags in the SMB3 security descriptor. It also makes the ACE type of the special SID better match the documentation (and behavior of servers which use this to store mode bits in SMB3 ACLs).

net: avoid an indirect call in ____sys_recvmsg()
CONFIG_RETPOLINE=y made indirect calls expensive. gcc seems to add an indirect call in ____sys_recvmsg(). Rewriting the code slightly makes sure to avoid this indirection. Alternative would be to not call sock_recvmsg() and instead use security_socket_recvmsg() and sock_recvmsg_nosec(), but this is less readable IMO.

tipc: fix ordering of tipc module init and exit routine
In order to set/get/dump, the tipc uses the generic netlink
infrastructure. So, when tipc module is inserted, init function
calls genl_register_family().
After genl_register_family(), set/get/dump commands are immediately
allowed and these callbacks internally use the net_generic.
net_generic is allocated by register_pernet_device() but this
is called after genl_register_family() in the __init function.
So, these callbacks would use un-initialized net_generic.
Test commands:
#SHELL1
while :
do
modprobe tipc
modprobe -rv tipc
done
#SHELL2
while :
do
tipc link list
done

mqprio: Fix out-of-bounds access in mqprio_dump
When user runs a command like
tc qdisc add dev eth1 root mqprio
KASAN stack-out-of-bounds warning is emitted.
Currently, NLA_ALIGN macro used in mqprio_dump provides too large
buffer size as argument for nla_put and memcpy down the call stack.
The flow looks like this:
1. nla_put expects exact object size as an argument;
2. Later it provides this size to memcpy;
3. To calculate correct padding for SKB, nla_put applies NLA_ALIGN
macro itself.
Therefore, NLA_ALIGN should not be applied to the nla_put parameter.
Otherwise it will lead to out-of-bounds memory access in memcpy.

The stmmac_tx_err() does zero indices to Tx descriptors, but does not reset HW current Tx descriptor address.

enetc: disable EEE autoneg by default
The EEE support has not been enabled on ENETC, but it may connect to a PHY which supports EEE and advertises EEE by default, while its link partner also advertises EEE. If this happens, the PHY enters low power mode when the traffic rate is low and causes packet loss. This patch disables EEE advertisement by default for any PHY that ENETC connects to, to prevent the above unwanted outcome.

Pull more block and io_uring updates from Jens Axboe:
"I wasn't expecting this to be so big, and if I was, I would have used
separate branches for this. Going forward I'll be doing separate
branches for the current tree, just like for the next kernel version
tree. In any case, this contains:
- Series from Christoph that fixes an inherent race condition with
zoned devices and revalidation.
- null_blk zone size fix (Damien)
- Fix for a regression in this merge window that caused busy spins by
sending empty disk uevents (Eric)
- Fix for a regression in this merge window for bfq stats (Hou)
- Fix for io_uring creds allocation failure handling (me)
- io_uring -ERESTARTSYS send/recvmsg fix (me)
- Series that fixes the need for applications to retain state across
async request punts for io_uring. This one is a bit larger than I
would have hoped, but I think it's important we get this fixed for
5.5.
- connect(2) improvement for io_uring, handling EINPROGRESS instead
of having applications needing to poll for it (me)
- Have io_uring use a hash for poll requests instead of an rbtree.
This turned out to work much better in practice, so I think we
should make the switch now. For some workloads, even with a fair
amount of cancellations, the insertion sort is just too expensive.
(me)
- Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
- Fix for brd unaligned IO, and a warning for the future (Ming)
- Fix for a bio integrity data leak (Justin)
- bvec_iter_advance() improvement (Pavel)
- Xen blkback page unmap fix (SeongJae)
The major items in here are all well tested, and on the liburing side
we continue to add regression and feature test cases. We're up to 50
topic cases now, each with anywhere from 1 to more than 10 cases in
each"

Pull vfs d_inode/d_flags memory ordering fixes from Al Viro:
"Fallout from tree-wide audit for ->d_inode/->d_flags barriers use.
Basically, the problem is that negative pinned dentries require
careful treatment - unless ->d_lock is locked or parent is held at
least shared, another thread can make them positive right under us.
Most of the uses turned out to be safe - the main surprises as far as
filesystems are concerned were
- race in dget_parent() fastpath, that might end up with the caller
observing the returned dentry _negative_, due to insufficient
barriers. It is positive in memory, but we could end up seeing the
wrong value of ->d_inode in CPU cache. Fixed.
- manual checks that result of lookup_one_len_unlocked() is positive
(and rejection of negatives). Again, insufficient barriers (we
might end up with inconsistent observed values of ->d_inode and
->d_flags). Fixed by switching to a new primitive that does the
checks itself and returns ERR_PTR(-ENOENT) instead of a negative
dentry. That way we get rid of boilerplate converting negatives
into ERR_PTR(-ENOENT) in the callers and have a single place to
deal with the barrier-related mess - inside fs/namei.c rather than
in every caller out there.
The guts of pathname resolution *do* need to be careful - the race
found by Ritesh is real, as well as several similar races.
Fortunately, it turns out that we can take care of that with fairly
local changes in there.
The tree-wide audit had not been fun, and I hate the idea of repeating
it. I think the right approach would be to annotate the places where
we are _not_ guaranteed ->d_inode/->d_flags stability and have sparse
catch regressions. But I'm still not sure what would be the least
invasive way of doing that and it's clearly the next cycle fodder"
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
fs/namei.c: fix missing barriers when checking positivity
fix dget_parent() fastpath race

This series of changes contains fixes for few SoC and board specific issues that would be good to have merged for v5.5-rc1: - Fix incorrect MMC card detection polarity for omap3-tao3530 - Fix wrong am57xx-beagle-x15 pinmux named states for eMMC - Fix dra7 cpsw mdio clock that causes wrong speed - Fix vcsi for droid4 so it won't get turned off after init - Fix rev and sysconfig register offsets for omap4 sgx so it can idle Then there are also two minor late changes to logicpd-torpedo-baseboard to configure 1-wire HDQ for battery stats, and remove out of date workaround comments no longer needed. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAl3enk4RHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXORmhAA3MvMUSvfo3qOH+7kktlFFzAPWvFAkcCm jKjAEOY1b0wBJkTVY9vUEL8+UHrqDguxNz7JgVqi7GXbJvafc0C1KoFbbohPncPK bzao7o2lAgje1NQ+cBIFVrqYLHPX3uxKKeTwnqIeti47fF48eIqVG2soKBEGAGpR R6/9WfK7Gd2NA/OGPfKX4h8ggm1nXnTZWwfM53I4JjW+36G5ZgpFxdQ5GdNw2uk3 iXttxuigkEMS3dR+Wlphquf2kDmIhKgc+UQq3N13s6Axb/FyM7CBNuoCTS/63VXP 7j34/W43/Ehhjrssp35r0psEkqO23BzWo2HpmPjMpa8XSu0MrRMWBqzwGKCN92UQ KSVwvydBm6QL/WrMXGYlkEs73N/bHpX2Tb22EdhmbL7zpS+1D14g9t7qRvuF/AnE ubsNzl9Eh9hma4EFvVP+YETpuOMJ9lhgAz/aEUiTPV/AINDfyJkDFP9/feP9DUzj BJkthGbMGdmTbGIZ+fQ2E8fXVpNVFRNBwZ0mmjYm4EbG1pbroGiDXByNv9sTusPn e1x9aU9fOqrY0OAr7SR2s1/d3E3MntW6lzBYehNdA0C3NMutrxULqxXAksYwkOud S6f6uV2Uq9DumapwbKkC7GKaHtONW6ocKmfraH7S+CIbvohfR3FBBdCNtqM84XOE EBtdBX7ToBQ= =2L5D -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.5/dt-fixes-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Device tree fixes for omap variants for for v5.5 merge window This series of changes contains fixes for few SoC and board specific issues that would be good to have merged for v5.5-rc1: - Fix incorrect MMC card detection polarity for omap3-tao3530 - Fix wrong am57xx-beagle-x15 pinmux named states for eMMC - Fix dra7 cpsw mdio clock that causes wrong speed - Fix vcsi for droid4 so it won't get turned off after init - Fix rev and sysconfig register offsets for omap4 sgx so it can idle Then there are also two minor late changes to logicpd-torpedo-baseboard to configure 1-wire HDQ for battery stats, and remove out of date workaround comments no longer needed. * tag 'omap-for-v5.5/dt-fixes-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Fix sgx sysconfig register for omap4 ARM: dts: Fix vcsi regulator to be always-on for droid4 to prevent hangs ARM: dts: dra7: fix cpsw mdio fck clock ARM: dts: am57xx-beagle-x15: Update pinmux name to ddr_3_3v ARM: dts: omap3-tao3530: Fix incorrect MMC card detection GPIO polarity ARM: dts: logicpd-torpedo: Remove unnecessary notes/comments ARM: dts: logicpd-torpedo-baseboard: Enable HDQ Link: https://lore.kernel.org/r/pull-1574870758-237468@atomide.com Signed-off-by: Olof Johansson <olof@lixom.net> |

Few ti-sysc related fixes for v5.5 merge window
Just few minor changes that can be merged when suitable, but would be good to have these in v5.5-rc1 to remove dependencies between branches for more changes later on in v5.6: - Add quirk handling for AESS (Audio Engine Sub System) - We want to drop the useless gptimer option for omap4 as there are local timers - A minor error path handling improvment for sysc_child_add_named_clock() that will make further patching a bit easier -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAl3VgmMRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXOMhQ/+KJPQ0n0MUOOBZAE67u0/lxQLjljBWCWC ngvTm6Kcf9r+PgmRit0jgXNGbTq7CIuy3h46+dUDqcusn9YTfRfhyPnAr4YPq0o+ RWwIILritkVmp0tNdiKhE2QXPB0pgNEM3KITzz1W0KqB+ZOqOYtgtc0ZTXO6QdZ6 3TLNQGw613fFyfPRTlLsBzHrPUmf4oRY+P7qPWTemvgxtDouyR9E6gMKonr8KJRj c6jZGhoOfDmBgJR52vVeuCUea+hK5rJ8GghlDbIijxXPV3YdGLFp4AD0bBD973p0 vIZMD3fU9VbvK/e2gjrfwykqwda8MNzMeXAS9GwkVOtTE9/4aSGhIN9Pw26a5pLS yy5MIkPCsekcCMp2Jsg5KEp9RRrVhJrzg1m9M9S8TCQ4cIk1R8+aieCVaQZMJyiH sl2/adC7XilTJFk76Iq5p4Vo50b8cdGQoGgAdHNkaFa2JVt8VFZ0ZcRcTgQc5irZ wIT/dp7DZiXu4Ap2tbM49Gc8Nk/RZ2/aHQnnrVsYyyWRnBLQEmILwwsYlYPjyyeO +369FQTM2H1CM68BkKOJv/AcvwERm5BOBCcp3+XN0ZWa6Tckw8wPQ1rghtxfESgl hrNMigT7UV6Dc9DlC3tqz++GfmPYs5ws1/qTmckczgRFthIDx9OTMZ+u73xF2XnM kYET/Yj4gzY= =Yb3M -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Few ti-sysc related fixes for v5.5 merge window Just few minor changes that can be merged when suitable, but would be good to have these in v5.5-rc1 to remove dependencies between branches for more changes later on in v5.6: - Add quirk handling for AESS (Audio Engine Sub System) - We want to drop the useless gptimer option for omap4 as there are local timers - A minor error path handling improvment for sysc_child_add_named_clock() that will make further patching a bit easier * tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Adjust exception handling in sysc_child_add_named_clock() ARM: OMAP2+: Drop useless gptimer option for omap4 bus: ti-sysc: Add module enable quirk for audio AESS Link: https://lore.kernel.org/r/pull-1574273726-31367@atomide.com Signed-off-by: Olof Johansson <olof@lixom.net> |

arm64: entry: refine comment of stack overflow check
Stack overflow checking can be done by testing sp & (1 << THREAD_SHIFT) only for the stacks are aligned to (2 << THREAD_SHIFT) with size of (1 << THREAD_SIZE), and this is the case when CONFIG_VMAP_STACK is set. Fix the code comment to avoid confusion.
