Per confirmation with RLC firmware team, the RLC should
be unhalted after all RLC related firmwares uploaded.
However, in fact the RLC is unhalted immediately after
RLCG firmware uploaded. And that may causes unexpected
PSP hang on loading the succeeding RLC save restore
list related firmwares.
So, we correct the firmware loading sequence to load
RLC save restore list related firmwares before RLCG
ucode. That will help to get around this issue.

Pull RISC-V fixes from Paul Walmsley:
"One important fix for RISC-V:
- Redirect any incoming syscall with an ID less than -1 to
sys_ni_syscall, rather than allowing them to fall through into the
syscall handler.
and two minor build fixes:
- Export __asm_copy_{from,to}_user() from where they are defined.
This fixes a build error triggered by some randconfigs.
- Export flush_icache_all(). I'd resisted this before, since
historically we didn't want modules to be able to flush the I$
directly; but apparently everyone else is doing it now"

This is needed by LKDTM (crash dump test module), it calls
flush_icache_range(), which on RISC-V turns into flush_icache_all(). On
other architectures, the actual implementation is exported, so follow
that precedence and export it here too.
Fixes build of CONFIG_LKDTM that fails with:
ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined!

Running "stress-ng --enosys 4 -t 20 -v" showed a large number of kernel oops
with "Unable to handle kernel paging request at virtual address" message. This
happens when enosys stressor starts testing random non-valid syscalls.
I forgot to redirect any syscall below -1 to sys_ni_syscall.
With the patch kernel oops messages are gone while running stress-ng enosys
stressor.

Fixes: 5340627e3f ("riscv: add support for SECCOMP and SECCOMP_FILTER")
Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
When support for !MMU was added, the declaration of
__asm_copy_to_user() & __asm_copy_from_user() were #ifdefed
out hence their EXPORT_SYMBOL() give an error message like:
.../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here
.../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here
Since these symbols are not defined with !MMU it's wrong to export them.
Same for __clear_user() (even though this one is also declared in
include/asm-generic/uaccess.h and thus doesn't give an error message).
Fix this by doing the EXPORT_SYMBOL() directly where these symbols
are defined: inside lib/uaccess.S itself.
Fixes: 6bd33e1ece ("riscv: fix compile failure with EXPORT_SYMBOL() & !MMU")

Pull io_uring fixes from Jens Axboe:
- Removal of now unused busy wqe list (Hillf)
- Add cond_resched() to io-wq work processing (Hillf)
- And then the series that I hinted at from last week, which removes
the sqe from the io_kiocb and keeps all sqe handling on the prep
side. This guarantees that an opcode can't do the wrong thing and
read the sqe more than once. This is unchanged from last week, no
issues have been observed with this in testing. Hence I really think
we should fold this into 5.5.
