Merge page ref overflow branch.
Jann Horn reported that he can overflow the page ref count with
sufficient memory (and a filesystem that is intentionally extremely
slow).
Admittedly it's not exactly easy. To have more than four billion
references to a page requires a minimum of 32GB of kernel memory just
for the pointers to the pages, much less any metadata to keep track of
those pointers. Jann needed a total of 140GB of memory and a specially
crafted filesystem that leaves all reads pending (in order to not ever
free the page references and just keep adding more).
Still, we have a fairly straightforward way to limit the two obvious
user-controllable sources of page references: direct-IO like page
references gotten through get_user_pages(), and the splice pipe page
duplication. So let's just do that.
* branch page-refs:
fs: prevent page refcount overflow in pipe_buf_get
mm: prevent get_user_pages() from overflowing page refcount
mm: add 'try_get_page()' helper function
mm: make page ref count overflow check tighter and more explicit

qed: Fix the Doorbell Overflow Recovery mechanism
This patch series fixes and improves the doorbell recovery mechanism.
The main goals of this series are to fix missing attentions from the
doorbells block (DORQ) or not handling them properly, and execute the
recovery from periodic handler instead of the attention handler.
Please consider applying the series to net.

Separate the overflow handling from the hardware interrupt status analysis.
The interrupt status is a single register and is common for all PFs. The
first PF reading the register is not necessarily the one who overflowed.
All PFs must check their overflow status on every attention.
In this change we clear the sticky indication in the attention handler to
allow doorbells to be processed again as soon as possible, but running
the doorbell recovery is scheduled for the periodic handler to reduce the
time spent in the attention handler.
Checking the need for DORQ flush was changed to "db_bar_no_edpm" because
qed_edpm_enabled()'s result could change dynamically and might have
prevented a needed flush.

When the DORQ (doorbell block) is overflowed, all PFs get attentions at the
same time. If one PF finished handling the attention before another PF even
started, the second PF might miss the DORQ's attention bit and not handle
the attention at all.
If the DORQ attention is missed and the issue is not resolved, another
attention will not be sent, therefore each attention is treated as a
potential DORQ attention.
As a result, the attention callback is called more frequently so the debug
print was moved to reduce its quantity.
The number of periodic doorbell recovery handler schedules was reduced
because it was the previous way to mitigating the missed attention issue.

DB_REC_DRY_RUN (running doorbell recovery without sending doorbells) is
never used. DB_REC_ONCE (send a single doorbell from the doorbell recovery)
is not needed anymore because by running the periodic handler we make sure
we check the overflow status later instead.
This patch is needed because in the next patches, the only doorbell
recovery type being used is DB_REC_REAL_DEAL, and the fixes are much
cleaner without this enum.

In original codes, ndo_set_vf_vlan() in hns3 driver was implemented
wrong. It adds or removes VLAN into VLAN filter for VF, but VF is
unaware of it.
This patch fixes it. When VF loads up, it firstly queries the port
based VLAN state from PF. When user change port based VLAN state
from PF, PF firstly checks whether the VF is alive. If the VF is
alive, then PF notifies the VF the modification; otherwise PF
configure the port based VLAN state directly.

Currently, in TX direction, driver implements the TX VLAN offload
by checking the VLAN header in skb, and filling it into TX descriptor.
Usually it works well, but if enable inserting VLAN header based on
port, it may conflict when out_tag field of TX descriptor is already
used, and cause RAS error.
In RX direction, hardware supports stripping max two VLAN headers.
For vlan_tci in skb can only store one VLAN tag, when RX VLAN offload
enabled, driver tells hardware to strip one VLAN header from RX
packet; when RX VLAN offload disabled, driver tells hardware not to
strip VLAN header from RX packet. Now if port based insert VLAN
enabled, all RX packets will have the port based VLAN header. This
header is useless for stack, driver needs to ask hardware to strip
it. Unfortunately, hardware can't drop this VLAN header, and always
fill it into RX descriptor, so driver has to identify and drop it.

Our hardware supports inserting a specified VLAN header for each
function when sending packets. User can enable it with command

For this VLAN header is inserted by hardware, not from stack,
hardware also needs to strip it from received packets before
sending to stack. In this case, driver needs to tell
hardware which VLAN to insert or strip.

This is the same as the traditional 'get_page()' function, but instead
of unconditionally incrementing the reference count of the page, it only
does so if the count was "safe". It returns whether the reference count
was incremented (and is marked __must_check, since the caller obviously
has to be aware of it).
Also like 'get_page()', you can't use this function unless you already
had a reference to the page. The intent is that you can use this
exactly like get_page(), but in situations where you want to limit the
maximum reference count.
The code currently does an unconditional WARN_ON_ONCE() if we ever hit
the reference count issues (either zero or negative), as a notification
that the conditional non-increment actually happened.
NOTE! The count access for the "safety" check is inherently racy, but
that doesn't matter since the buffer we use is basically half the range
of the reference count (ie we look at the sign of the count).

We have a VM_BUG_ON() to check that the page reference count doesn't
underflow (or get close to overflow) by checking the sign of the count.
That's all fine, but we actually want to allow people to use a "get page
ref unless it's already very high" helper function, and we want that one
to use the sign of the page ref (without triggering this VM_BUG_ON).
Change the VM_BUG_ON to only check for small underflows (or _very_ close
to overflowing), and ignore overflows which have strayed into negative
territory.

A minor build fix for 64-bit FLATMEM configs.
A fix for a boot failure on 32-bit powermacs.
My commit to fix CLOCK_MONOTONIC across Y2038 broke the 32-bit VDSO on 64-bit
kernels, ie. compat mode, which is only used on big endian.
The rewrite of the SLB code we merged in 4.20 missed the fact that the 0x380
exception is also used with the Radix MMU to report out of range accesses. This
could lead to an oops if userspace tried to read from addresses outside the user
or kernel range.

In five of the drivers, the contents of bits 29-31 of one of the RX
descriptors is used to set bits in a variable that is used to save the
wakeup condition for output in a debugging statement. The resulting
variable is not used anywhere else even though it is stored in a struct
and could be available in other routines. This variable is changed to be
local.

In drivers rtl8188ee, rtl8821ae, rtl8723be, and rtl8192ee, the reason
for a wake-up is returned in the fourth RX descriptor in bits 29-31. Due
to typographical errors, all but rtl8821ae test bit 31 twice and fail to
test bit 29.
This error causes no problems as the tests are only used to set bits in
the output of an optional debugging statement.

error return path leaks mypkt. Fix this by returning by a new
