afa965a4 ("drm/rockchip: vop2: fix suspend/resume") uses
regmap_reinit_cache() to fix the suspend/resume issue with the VOP2
driver. During discussion it came up that we should rather use
regcache_sync() instead. As the original patch is already applied
fix this up in this follow-up patch.

Commit 41d351f2 ("drm/nouveau: stop using ttm_bo_wait")
converted from ttm_bo_wait_ctx() to dma_resv_wait_timeout().
However, dma_resv_wait_timeout() returns greater than zero on
success as opposed to ttm_bo_wait_ctx(). As a result, relocs
will fail and log errors even when it was a success.

Change the return code handling to match that of
nouveau_gem_ioctl_cpu_prep(), which was already using
dma_resv_wait_timeout() correctly.

During a suspend/resume cycle the VO power domain will be disabled and
the VOP2 registers will reset to their default values. After that the
cached register values will be out of sync and the read/modify/write
operations we do on the window registers will result in bogus values
written. Fix this by re-initializing the register cache each time we
enable the VOP2. With this the VOP2 will show a picture after a
suspend/resume cycle whereas without this the screen stays dark.

Commit 05e96e96 ("kbuild: use git-archive for source package

the common build rules.

With the previous commit, we got back to the situation where source
tarballs are compressed on-the-fly.
There is no reason to keep the separate compression rules.

Generate the comressed tar packages directly.

Since commit 05e96e96 ("kbuild: use git-archive for source package
creation"), a source tarball is created in two steps; create *.tar file
then compress it. I split the compression as a separate rule because I
just thought 'git archive' supported only gzip.

For other compression algorithms, I could pipe the two commands:

  $ git archive HEAD | xz > linux.tar.xz

I read git-archive(1) carefully, and I realized GIT had provided a
more elegant way:

  $ git -c tar.tar.xz.command=xz archive -o linux.tar.xz HEAD

This commit uses 'tar.tar.*.command' configuration to specify the
compression backend so we can compress a source tarball on-the-fly.

GIT commit 767cf4579f0e ("archive: implement configurable tar filters")
is more than a decade old, so it should be available on almost all build
environments.

Forwarding variadic argument lists can't be done by passing a va_list
to a function with signature foo(...) (as panic() has). It ends up
interpreting the va_list itself as a single argument instead of
iterating it. printf() happily accepts it of course, leading to corrupt
output.

Convert panic_show_mem() to a macro to allow forwarding the arguments.
The function is trivial enough that it's easier than trying to introduce
a vpanic() variant.

Similar to commit 4c9d410f ("initramfs: Check timestamp to prevent
broken cpio archive"), except asserts that the timestamp is
non-negative. This can happen when the KBUILD_BUILD_TIMESTAMP is a value
before UNIX epoch, which may be set when making reproducible builds that
don't want to look like they use a valid date.

While support for dates before 1970 might not be supported, this is more
about preventing undetected CPIO corruption. The printf's use a minimum
length format specifier, and will happily make the field longer than 8
characters if they need to.

So far io_req_complete_post() only covers DEFER_TASKRUN by completing
request via task work when the request is completed from IOWQ.

However, uring command could be completed from any context, and if io
uring is setup with DEFER_TASKRUN, the command is required to be
completed from current context, otherwise wait on IORING_ENTER_GETEVENTS
can't be wakeup, and may hang forever.

The issue can be observed on removing ublk device, but turns out it is
one generic issue for uring command & DEFER_TASKRUN, so solve it in
io_uring core code.

riscv establishes 2 virtual mappings:

- early_pg_dir maps the kernel which allows to discover the system
  memory
- swapper_pg_dir installs the final mapping (linear mapping included)

We used to map the dtb in early_pg_dir using DTB_EARLY_BASE_VA, and this
mapping was not carried over in swapper_pg_dir. It happens that
early_init_fdt_scan_reserved_mem() must be called before swapper_pg_dir is
setup otherwise we could allocate reserved memory defined in the dtb.
And this function initializes reserved_mem variable with addresses that
lie in the early_pg_dir dtb mapping: when those addresses are reused
with swapper_pg_dir, this mapping does not exist and then we trap.

The previous "fix" was incorrect as early_init_fdt_scan_reserved_mem()
must be called before swapper_pg_dir is set up otherwise we could
allocate in reserved memory defined in the dtb.

So move the dtb mapping in the fixmap region which is established in
early_pg_dir and handed over to swapper_pg_dir.

For gfx_rings the schedulers may not be initialized by
amdgpu_device_init_schedulers() due to ring->no_scheduler flag being set to
true and thus the timeout_wq is NULL. As a result, since all ASICs call
drm_sched_fault() unconditionally even for schedulers which have not been
initialized, it is simpler to use the ready condition which indicates whether
the given scheduler worker thread runs and whether the timeout_wq of the reset
domain has been initialized.
