It's better to keep all hardware GGTT definitions separated from
the driver code. It also helps to avoid duplicated definitions.

The actual problem here is that it does not understand the special
%pOFn format string and assumes that it is a pointer followed by
the string "OFn", which would indeed not fit.
Slightly increasing the size of the buffer to its natural alignment
avoids the warning, as it is now long enough for the correct and

Last kernel release we introduce CONFIG_BLK_DEV_WRITE_MOUNTED. By
default this option is set. When it is set the long-standing behavior
of being able to write to mounted block devices is enabled.
But in order to guard against unintended corruption by writing to the
block device buffer cache CONFIG_BLK_DEV_WRITE_MOUNTED can be turned
off. In that case it isn't possible to write to mounted block devices
anymore.
A filesystem may open its block devices with BLK_OPEN_RESTRICT_WRITES
which disallows concurrent BLK_OPEN_WRITE access. When we still had the
bdev handle around we could recognize BLK_OPEN_RESTRICT_WRITES because
the mode was passed around. Since we managed to get rid of the bdev
handle we changed that logic to recognize BLK_OPEN_RESTRICT_WRITES based
on whether the file was opened writable and writes to that block device
are blocked. That logic doesn't work because we do allow
BLK_OPEN_RESTRICT_WRITES to be specified without BLK_OPEN_WRITE.
Fix the detection logic and use an FMODE_* bit. We could've also abused
O_EXCL as an indicator that BLK_OPEN_RESTRICT_WRITES has been requested.
For userspace open paths O_EXCL will never be retained but for internal
opens where we open files that are never installed into a file
descriptor table this is fine. But it would be a gamble that this
doesn't cause bugs. Note that BLK_OPEN_RESTRICT_WRITES is an internal
only flag that cannot directly be raised by userspace. It is implicitly
raised during mounting.
Passes xftests and blktests with CONFIG_BLK_DEV_WRITE_MOUNTED set and
unset.

Subtracting async_copy_bytes is correct in both peek and !peek cases,
because decrypted == async_copy_bytes + peeked for the peek case: peek
is always !ZC, and we can go through either the sync or async path. In
the async case, we add chunk to both decrypted and

Refactor xe_sync_entry_signal so it doesn't have to
modify xe_sched_job struct instead create a new helper function
to set user fence values for a job.
v2: Move the sync type check to xe_sched_job_init_user_fence(Lucas)

SLPC shutdown is called in reset and suspend paths. In the reset
path, it is possible that the H2G call gets lost as GuC is in the
process of being reset. There is no value in stopping SLPC when
it will happen anyways.
In the suspend path, we disable communication with GuC, so there
is no need to explicitly shutdown SLPC.
v2: Rebase

RISC-V perf driver does not yet support branch sampling. Although the
specification is in the works [0], it is best to disable such events
until support is available, otherwise we will get unexpected results.
Due to this reason, two riscv bpf testcases get_branch_snapshot and
perf_branches/perf_branches_hw fail.

'make vdso_install' installs debug vdso files to /lib/modules/*/vdso/.
Only for the compat vdso on riscv, the installation destination differs;
compat_vdso.so.dbg is installed to /lib/module/*/compat_vdso/.
To follow the standard install destination and simplify the vdso_install
logic, change the install destination to standard /lib/modules/*/vdso/.
