Right now io_flush_timeouts() checks if the current number of events
is equal to ->timeout.target_seq, but this will miss some timeouts if
there have been more than 1 event added since the last time they were
flushed (possible in io_submit_flush_completions(), for example). Fix
it by recording the last sequence at which timeouts were flushed so
that the number of events seen can be compared to the number of events
needed without overflow.

The kbuild test robot reports that when building with W=1, GCC will warn
for a couple of missing prototypes in syscall.c:
| arch/arm64/kernel/syscall.c:157:6: warning: no previous prototype for 'do_el0_svc' [-Wmissing-prototypes]
| 157 | void do_el0_svc(struct pt_regs *regs)
| | ^~~~~~~~~~
| arch/arm64/kernel/syscall.c:164:6: warning: no previous prototype for 'do_el0_svc_compat' [-Wmissing-prototypes]
| 164 | void do_el0_svc_compat(struct pt_regs *regs)
| | ^~~~~~~~~~~~~~~~~
While this isn't a functional problem, as a general policy we should
include the prototype for functions wherever possible to catch any
accidental divergence between the prototype and implementation. Here we
can easily include <asm/exception.h>, so let's do so.
While there are a number of warnings elsewhere and some warnings enabled
under W=1 are of questionable benefit, this change helps to make the
code more robust as it evolved and reduces the noise somewhat, so it
seems worthwhile.

The last remaining usage of strlcpy() in USB-audio driver is the setup
of the card longname string. Basically we need to know whether any
non-empty string is set or not, and no real length is needed.
Refactor the code and use strscpy() instead. After this change,
strlcpy() is gone from all sound/* code.

USB-audio driver still contains two calls of strlcpy() because the
return size is evaluated. Basically it just checks whether the string
is copied or not, but since strcpy() may return a negative error code,
we should check the negative value and treat as filled.

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to
have been updated for use by the x86 VBIOS code, so we should be able to
continue using them for the moment.
Unfortunately, we require some hacks to do so, as the BeforeLinkTraining
IED script became a pointer to an array of scripts instead, without a
revbump of the relevant tables.
There's also some changes to SOR clock divider fiddling, which are
hopefully correct enough that things work as they should.
AFAIK, GA100 shouldn't have display, so it hasn't been added.

Fortunately, all the interrupts we need to bring up basic display support
are contained in a single leaf register, allowing this basic (but hackish)
implementation.
There's a bunch more invasive patches to come implementing all this in a
better/more complete way, but trying to get a minimal series out first.

This issue has generally been covered up by the presence of additional
expansion ROMs after the ones we're interested in, with header fetches
of subsequent images loading enough of the ROM to hide the issue.
Noticed on GA102, which lacks a type 0x70 image compared to TU102,.
