jevents.c uses nftw() to enumerate files and outputs the corresponding
C structs in the order they are found.  This makes it sensitive to
directory ordering, so that the perf executable is not reproducible.

To avoid this, store all the files and directories found and then sort
them by their (relative) path.  (This maintains the parent-first
ordering that nftw() promises.)  Then apply the existing callbacks to
them in the sorted order.

Bug: https://xenbits.xen.org/xsa/advisory-350.html
Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2020-29569

When xen_blkif_disconnect() is called, the kernel thread behind the
block interface is stopped by calling kthread_stop(ring->xenblkd).
The ring->xenblkd thread pointer being non-NULL determines if the
thread has been already stopped.
Normally, the thread's function xen_blkif_schedule() sets the
ring->xenblkd to NULL, when the thread's main loop ends.

However, when the thread has not been started yet (i.e.
wake_up_process() has not been called on it), the xen_blkif_schedule()
function would not be called yet.

In such case the kthread_stop() call returns -EINTR and the
ring->xenblkd remains dangling.
When this happens, any consecutive call to xen_blkif_disconnect (for
example in frontend_changed() callback) leads to a kernel crash in
kthread_stop() (e.g. NULL pointer dereference in exit_creds()).

This is XSA-350.

Fortunately, some watch events could be ignored, depending on its

Due to db/dbx are authenticated variables, they needs manufacturer's

the only differences on syscall entry are a few instructions that mask
out the x32 flag and compare the syscall number.

The xen-privcmd driver, which can be modular, calls set_pte_at()
which in turn may call __sync_icache_dcache().

The call to __sync_icache_dcache() may be optimised out because it is

However, in a non-LPAE configuration there is no "special" bit and the

radeon requires firmware/microcode for the GPU in all chips, but for
newer chips (apparently R600 'Evergreen' onward) it also expects
firmware for the memory controller and other sub-blocks.

radeon attempts to gracefully fall back and disable some features if
the firmware is not available, but becomes unstable - the framebuffer
and/or system memory may be corrupted, or the display may stay black.

Therefore, perform a basic check for the existence of
/lib/firmware/{radeon,amdgpu} when a device is probed, and abort if it
is missing, except for the pre-R600 case.

firmware_class: Log every success and failure against given device

The hundreds of users of request_firmware() have nearly as many
different log formats for reporting failures.  They also have only the
vaguest hint as to what went wrong; only firmware_class really knows
that.  Therefore, add specific log messages for the failure modes that
aren't currently logged.

In case of a driver that tries multiple names, this may result in the
impression that it failed to initialise.  Therefore, also log successes.

This makes many error messages in drivers redundant, which will be
removed in later patches.

This does not cover the case where we fall back to a user-mode helper
(which is no longer enabled in Debian).

NOTE: hw-detect will depend on the "firmware: failed to load %s (%d)\n"

Here's a patch that simply uses hardcoded definitions instead of
doing the dynamic tests that require architecture-specific scripts.

I don't particularly like this approach because it restricts
portability and diverts from upstream. But, it is simpler, and this
really needs to be fixed somehow before etch (along with a rebuild of
linux-modules-extra-2.6), so I'm willing to live with it if my other
patch is deemed unacceptable.

My primary concern is that, in the future, the output of these scripts
will change and we (or our successors) will either not notice or
forget to update the hardcoded values.

Including the scripts in linux-kbuild will avoid this manual step
altogether, and allow for the possibility of other archs to provide
their own scripts in the future.
