Alex Deucher 855f5f1d88 drm/radeon: fix panel scaling with eDP and LVDS bridges
We were using the wrong set_properly callback so we always
ended up with Full scaling even if something else (Center or
Full aspect) was selected.

Alex Deucher 1cd8b21aa2 drm/radeon/dpm: rework auto performance level enable
Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.

Fixes dpm resume on SI.

Daniel Vetter d2aebe338a drm/udl: rip out set_need_resched
This very much looks like copypasta from drm/i915's fault handler.
It was used there to duct-tape over issues around gpu reset handling.

Since that can't ever happen for udl and there's seemingly no other
reason for this just drop it.

Davidlohr Bueso 6b02fa59a7 partitions/efi: loosen check fot pmbr size in lba
Matt found that commit 27a7c64217 ("partitions/efi: account for pmbr
size in lba") caused his GPT formatted eMMC device not to boot.  The
reason is that this commit enforced Linux to always check the lesser of
the whole disk or 2Tib for the pMBR size in LBA.  While most disk
partitioning tools out there create a pMBR with these characteristics,
Microsoft does not, as it always sets the entry to the maximum 32-bit
limitation - even though a drive may be smaller than that[1].

Loosen this check and only verify that the size is either the whole disk
or 0xFFFFFFFF.  No tool in its right mind would set it to any value
other than these.

Stephane Eranian 9d8e3f9693 perf/x86/intel: Mark MEM_LOAD_UOPS_MISS_RETIRED as precise on SNB
On Intel SNB (SNB, SNB-EP), the event MEM_LOAD_UOPS_MISS_RETIRED
supports PEBS. It was missing for the SNB PEBS event constraint
table thereby preventing any measurement with PEBS for it.

This patch adds the event to the PEBS table for SNB.

WARNING: it should be noted that this event like a few others
are subject to the erratum BT241 for Xeon E5 (SNB-EP). As such,
the event may undercount when used with PEBS unless the
workaround is implemented. But without this patch and just the
workaround, the kernel would not allow precise sampling on this
event. BT241 is documented in:

Linus Torvalds 89dc77bcda vfs: fix dentry LRU list handling and nr_dentry_unused accounting
The LRU list changes interacted badly with our nr_dentry_unused
accounting, and even worse with the new DCACHE_LRU_LIST bit logic.

This introduces helper functions to make sure everything follows the
proper dcache d_lru list rules: the dentry cache is complicated by the
fact that some of the hotpaths don't even want to look at the LRU list
at all, and the fact that we use the same list entry in the dentry for
both the LRU list and for our temporary shrinking lists when removing
things from the LRU.

The helper functions temporarily have some extra sanity checking for the
flag bits that have to match the current LRU state of the dentry.  We'll
remove that before the final 3.12 release, but considering how easy it
is to get wrong, this first cleanup version has some very particular
sanity checking.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to ixgbe and e1000e.

Jacob provides a ixgbe patch to fix the configure_rx patch to properly
disable RSC hardware logic when a user disables it.  Previously we only
disabled RSC in the queue settings, but this does not fully disable
hardware RSC logic which can lead to unexpected performance issues.

Emil provides three fixes for ixgbe.  First fixes the ethtool loopback
test when DCB is enabled, where the frames may be modified on Tx
(by adding VLAN tag) which will fail the check on receive.  Then a fix
for QSFP+ modules, limit the speed setting to advertise only one speed
at a time since the QSFP+ modules do not support auto negotiation.
Lastly, resolve an issue where the driver will display incorrect info
for QSFP+ modules that were inserted after the driver has been loaded.

David Ertman provides to fixes for e1000e, one removes a comparison to
the boolean value true where evaluating the lvalue will produce the
same result.  The other fixes an error in the calculation of the
rar_entry_count, which causes a write of unkown/undefined register
space in the MAC to unknown/undefined register space in the PHY.

When reading a single page with cifs_readpage(), we make a call to
fscache_read_or_alloc_page() which once done, asynchronously calls
the completion function cifs_readpage_from_fscache_complete(). This
completion function unlocks the page once it has been populated from
cache. The module then attempts to unlock the page a second time in
cifs_readpage() which leads to warning messages.

In case of a successful call to fscache_read_or_alloc_page() we should skip
the second unlock_page() since this will be called by the
cifs_readpage_from_fscache_complete() once the page has been populated by
fscache.

With the modifications to cifs_readpage_worker(), we will need to re-grab the
page lock in cifs_write_begin().

The problem was first noticed when testing new fscache patches for cifs.

Sachin Prabhu a9e9b7bc15 cifs: Do not take a reference to the page in cifs_readpage_worker()
We do not need to take a reference to the pagecache in
cifs_readpage_worker() since the calling function will have already
taken one before passing the pointer to the page as an argument to the
function.

David Ertman c3a0dce35a e1000e: fix overrun of PHY RAR array
When copying the MAC RAR registers to PHY there is an error in the
calculation of the rar_entry_count, which causes a write of unknown/
undefined register space in the MAC to unknown/undefined register space in
the PHY.

This patch fixes the overrun with writing to the PHY RAR and also fixes the
ethtool offline register tests so that the correctly addressed registers
have the appropriate bitmasks for R/W and RO bits for affected parts.

Shawn Rader gets credit for finding and fixing the register overrun.

This patch resolves an issue where the driver will display incorrect info
for Q/SFP+ modules that were inserted after the driver has been loaded.

calling get_link_capabilities() which needs the PHY data in order to
determine the correct settings.

Emil Tantilov ed33ff66d8 ixgbe: limit setting speed to only one at a time for QSFP modules
QSFP+ modules do not support auto negotiation and should advertise only
one speed at a time.

This patch adds logic in ethtool to allow setting and reporting the
advertised speed at either 1Gbps or 10Gbps, but not both. Also limits
the speed set in ixgbe_sfp_link_config_subtask() to highest supported.
Previously the link was set to whatever the supported speeds were.
