Better to unregister the file system before destroying the kmem_cache
cache of the inodes, so that the inodes are freed before we are trying
to destroy it. Otherwise, kmem_cache yells that some objects are live.

Implement client side caching for NFSv4.2 extended attributes. The cache
is a per-inode hashtable, with name/value entries. There is one special
entry for the listxattr cache.

NFS inodes have a pointer to a cache structure. The cache structure is
allocated on demand, freed when the cache is invalidated.

Memory shrinkers keep the size in check. Large entries (> PAGE_SIZE)
are collected by a separate shrinker, and freed more aggressively
than others.

Until now, change attributes in change_info form were only returned by
directory operations. However, they are also used for the RFC 8276
extended attribute operations, which work on both directories
and regular files.  Modify update_changeattr to deal:

* Rename it to nfs4_update_changeattr and make it non-static.
* Don't always use INO_INVALID_DATA, this isn't needed for a
  directory that only had its extended attributes changed by us.
* Existing callers now always pass in INO_INVALID_DATA.

For the current callers of this function, behavior is unchanged.

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build

Clang 8 was chosen as a minimum version for this check because there
were some improvements around __builtin_constant_p in that release. In
reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume
that we have a working compiler.

====================
mlxsw: Various fixes

Fix two issues found by syzkaller.

Patch #1 removes inappropriate usage of WARN_ON() following memory
allocation failure. Constantly triggered when syzkaller injects faults.

Patch #2 fixes a use-after-free that can be triggered by 'devlink dev
info' following a failed devlink reload.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

In case devlink reload failed, it is possible to trigger a
use-after-free when querying the kernel for device info via 'devlink dev
info' [1].

This happens because as part of the reload error path the PCI command
interface is de-initialized and its mailboxes are freed. When the
devlink '->info_get()' callback is invoked the device is queried via the
command interface and the freed mailboxes are accessed.

Fix this by initializing the command interface once during probe and not
during every reload.

This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c')
and also allows user space to query the running firmware version (for
example) from the device after a failed reload.

net: macb: Wake-on-Lan magic packet fixes and GEM handling

Here is a split series to fix WoL magic-packet on the current macb driver. Only
fixes in this one based on current net/master.

Changes in v5:
- Addressed the error code returned by phylink_ethtool_set_wol() as suggested
  by Russell.
  If PHY handles WoL, MAC doesn't stay in the way.
- Removed Florian's tag on 3/5 because of the above changes.
- Correct the "Fixes" tag on 1/5.

Changes in v4:
- Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
  sent later.

Changes in v3:
- Revert some of the v2 changes done in macb_resume(). Now the resume function
  supports in-depth re-configuration of the controller in order to deal with
  deeper sleep states. Basically as it was before changes introduced by this
  series
- Tested for non-regression with our deeper Power Management mode which cuts
  power to the controller completely

Changes in v2:
- Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
  needed for keeping phy state consistent
- Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent
  putting the macb in runtime pm suspend mode when WoL is used
- Collect review tags on 3 first patches from Florian: Thanks!
- Review of macb_resume() function
- Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The calls to pm_runtime_force_suspend/resume() functions are only
relevant if the device is not configured to act as a WoL wakeup source.
