[linuxsh-dev] siginfo, RTC initialization

[Jeremy S. <js...@mv...>]

Hi folks,

I'd like to apply the attached patches for a couple of problems I've
noticed in recent days.

(1) Sending signals via setup_rt_sigframe(): because __NR_rt_sigreturn is
> 127, the attempt to put it into R3 for the trap like
setup_sigframe() has a problem with sign-extension.  Corrected by adding
an extu.b instruction; copied same to setup_sigframe() for consistency.
Also, call setup for second and third arguments is incorrect, putting them
on stack rather than in r5/r6.  The patch to arch/sh/kernel/signal.c
attempts to fix these.

(2) In sh_rtc_gettimeofday() there is some code to check that the register
values are valid and reasonable; but in some cases I still get bogus
values into xtime at init.  The patch to arch/sh/kernel/rtc.c attempts to
tighten these checks.

Any objections to putting these in?  Anything I missed regarding these?

Thanks,
  --Jeremy
