sparc32: drop hardcoding trap_level in kgdb_trap 2016-05-21T00:55:41+00:00 Sam Ravnborg sam@ravnborg.org 2016-04-22T17:41:03+00:00 d097efa95059e6a36a365add3deaf43fcafc4067 Fix this so we pass the trap_level from the actual trap code like we do in sparc64. Add use on ENTRY(), ENDPROC() in the assembler function too. This fixes a bug where the hardcoded value for trap_level was the sparc64 value. As the generic code does not use the trap_level argument (for sparc32) - this patch does not have any functional impact. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

sparc: Fix system call tracing register handling. 2016-01-22T00:06:00+00:00 Mike Frysinger vapier@gentoo.org 2016-01-18T11:32:30+00:00 1a40b95374f680625318ab61d81958e949e0afe3 A system call trace trigger on entry allows the tracing process to inspect and potentially change the traced process's registers. Account for that by reloading the %g1 (syscall number) and %i0-%i5 (syscall argument) values. We need to be careful to revalidate the range of %g1, and reload the system call table entry it corresponds to into %l7. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: David S.
