This reverts merge 0f75ef6a9cff49ff612f7ce0578bced9d0b38325 (and thus
effectively commits
7a1ade847596 ("keys: Provide KEYCTL_GRANT_PERMISSION")
2e12256b9a76 ("keys: Replace uid/gid/perm permissions checking with an ACL")
that the merge brought in).
It turns out that it breaks booting with an encrypted volume, and Eric
biggers reports that it also breaks the fscrypt tests [1] and loading of
in-kernel X.509 certificates [2].
The root cause of all the breakage is likely the same, but David Howells
is off email so rather than try to work it out it's getting reverted in
order to not impact the rest of the merge window.

The pinning of sensitive CR0 and CR4 bits caused a boot crash when loading
the kvm_intel module on a kernel compiled with CONFIG_PARAVIRT=n.
The reason is that the static key which controls the pinning is marked RO
after init. The kvm_intel module contains a CR4 write which requires to
update the static key entry list. That obviously does not work when the key
is in a RO section.
With CONFIG_PARAVIRT enabled this does not happen because the CR4 write
uses the paravirt indirection and the actual write function is built in.
As the key is intended to be immutable after init, move
native_write_cr0/4() out of line.
While at it consolidate the update of the cr4 shadow variable and store the
value right away when the pinning is initialized on a booting CPU. No point
in reading it back 20 instructions later. This allows to confine the static
key and the pinning variable to cpu/common and allows to mark them static.

When cross-compiling an out-of-tree build with an unclean source tree
directory, the build fails with:
/path/to/kernel/source/tree is not clean, please run 'make mrproper'
in the '/path/to/kernel/source/tree' directory.
However, doing so does not fix the problem, as "make mrproper" now
requires passing the target architecture to the make command, else it
won't remove $(srctree)/arch/$(SRCARCH)/include/generated.
"git ls-files -o" doesn't give a clue, as it doesn't list (empty)
directories, only files.
Improve usability by including the ARCH= option in the error output.

In old days, Kbuild always used an absolute path for $(srctree).
Since commit 890676c65d69 ("kbuild: Use relative path when building in
the source tree"), $(srctree) is '.' when O= was not passed from the
command line.
Yet, using absolute paths is useful in some cases even without O=, for
instance, to create a cscope file with absolute path tags.
'O=.' was known to work as a workaround to force Kbuild to use absolute
paths even when you are building in the source tree.
Since commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any
directory"), Kbuild is too clever to be tricked. Even if you pass 'O=.'
Kbuild notices you are building in the source tree, then use '.' for
$(srctree).
So, 'make O=. cscope' is no help to create absolute path tags.
We cannot force one or the other according to commit e93bc1a0cab3
("Revert "kbuild: specify absolute paths for cscope""). Both of
relative path and absolute path have pros and cons.
This commit adds a new flag KBUILD_ABS_SRCTREE to allow users to
choose the absolute path for $(srctree).
'make KBUILD_ABS_SRCTREE=1 cscope' will work as a replacement of
'make O=. cscope'.

It is only used in tools/testing/selftest/ to distinguish out-of-tree

is a weakly defined function in eventfd.c, remove the declaration to

As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and
MFD glue") said, these MMC controllers use the IP from Panasonic.
TMIO (Toshiba Mobile IO) MMC was the first upstreamed user of this IP.
The common driver code was split and expanded as 'tmio-mmc-core', then
it became historical misnomer since 'tmio' is not the name of this IP.
In the discussion [1], we decide to keep this name as-is at least in
Linux driver level because renaming everything is a big churn.
However, DT should not be oriented to a particular project even though
it is mainly developed in Linux communities.
This is the misfortune only in Linux. Let's stop exporting it to other
projects, where there is no good reason to call this hardware "TMIO".
Rename the file to renesas,sdhi.txt. In fact, all the information in
this file is specific to the Renesas platform.
This commit also removes the first paragraph entirely. The DT-binding
should describe the hardware. It is strange to talk about Linux driver
internals such as how the drivers are probed, how platform data are
handed off, etc.

It looks like the original idea behind always doing a re-initialization of
a removable SDIO card during system resume in mmc_sdio_resume(), is to try
to play safe to detect whether the card has been removed.
However, this seems like a really a bad idea as it will most likely screw
things up, especially when the card is expected to remain powered on during
system suspend by the SDIO func driver.
Let's fix this, simply by trusting that the detect work checks if the card
is alive and inserted, which is being scheduled at the PM_POST_SUSPEND
notification anyway.

To use the so called powered-on re-initialization of an SDIO card, the
power to the card must obviously have stayed on. If not, the initialization
will simply fail.
In the runtime suspend case, the card is always powered off. Hence, let's
drop the support for powered-on re-initialization during runtime resume, as
it doesn't make sense.
Moreover, during a HW reset, the point is to cut the power to the card and
then do fresh re-initialization. Therefore drop the support for powered-on
re-initialization during HW reset.

In some cases, using the 'truncate' command to extend a UDF file results
in a mismatch between the length of the file's extents (specifically, due
to incorrect length of the final NOT_ALLOCATED extent) and the information
(file) length. The discrepancy can prevent other operating systems
(i.e., Windows 10) from opening the file.
Two particular errors have been observed when extending a file:
1. The final extent is larger than it should be, having been rounded up
to a multiple of the block size.
B. The final extent is not shorter than it should be, due to not having
been updated when the file's information length was increased.

of the switchdev SWITCHDEV_ATTR_ID_BRIDGE_MROUTER attribute.
The current behavior is kept unchanged but a user can now prevent
the CPU conduit to be flooded with a lot of unregistered traffic that
the network stack needs to filter in software with e.g.:
echo 0 > /sys/class/net/br0/multicast_router

Commit 9903c8dc7342 changed TC_ETF defines to use _BITUL instead of BIT
but did not add the dependecy on linux/const.h. As a consequence,
importing the uapi headers into iproute2 causes builds to fail. Add
the dependency.
Fixes: 9903c8dc7342 ("etf: Don't use BIT() in UAPI headers.")

On commit ba2b232108d3 ("net: netsec: add XDP support") a static
declaration for netsec_set_tx_de() was added to make the diff easier
to read. Now that the patch is merged let's move the functions around
and get rid of that
