## Description

In the Linux kernel, the following vulnerability has been resolved:
riscv: fix oops caused by irqsoff latency tracer
The trace\_hardirqs\_{on,off}() require the caller to setup frame pointer
properly. This because these two functions use macro 'CALLER\_ADDR1' (aka.
\_\_builtin\_return\_address(1)) to acquire caller info. If the $fp is used
for other purpose, the code generated this macro (as below) could trigger
memory access fault.
0xffffffff8011510e <+80>: ld a1,-16(s0)
0xffffffff80115112 <+84>: ld s2,-8(a1) # <-- paging fault here
The oops message during booting if compiled with 'irqoff' tracer enabled:

[ 0.046402][ T0] [<ffffffff80003b94>] restore\_all+0x12/0x6e
This because the $fp(aka. $s0) register is not used as frame pointer in the
assembly entry code.
resume\_kernel:
REG\_L s0, TASK\_TI\_PREEMPT\_COUNT(tp)
bnez s0, restore\_all
REG\_L s0, TASK\_TI\_FLAGS(tp)
andi s0, s0, \_TIF\_NEED\_RESCHED
beqz s0, restore\_all
call preempt\_schedule\_irq
j restore\_all
To fix above issue, here we add one extra level wrapper for function
trace\_hardirqs\_{on,off}() so they can be safely called by low level entry
code.
