2009-01-29sh: Fix up spurious syscall restarting.Paul Mundt
The T-bit manipulation for syscall error checking had the side effect of spuriously returning ERESTART* errno values over EINTR. So, we simplify the error checking a bit and leave the T-bit alone. Reported-by: Kaz Kojima <kkojima@rr.iij4u.or.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide asm/syscall.h for SH-5.Paul Mundt
This provides the asm/syscall.h implementation for sh64 parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Handle cases where setup{_rt,}_frame() fail on SH-5 signal delivery.Paul Mundt
Presently these cases are not handled properly due to the return value not being passed back. This needs to be correct to get proper behaviour out of things like the tracehook signal notifier, amongst others. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-08-02sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.Paul Mundt
This follows the changes in commits: 7d6d637dac2050f30a1b57b0a3dc5de4a10616ba 4f72c4279eab1e5f3ed1ac4e55d4527617582392 on powerpc. Adding in TIF_NOTIFY_RESUME, and cleaning up the syscall tracing to be more generic. This is an incremental step to turning on tracehook, as well as unifying more of the ptrace and signal code across the 32/64 split. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-16sh64: add missing #include <asm/fpu.h>'sAdrian Bunk
This patch fixes some compile errors due to missing save_fpu() prototypes on sh64 caused by commit 9bbafce2eec190ef7e44b0eb1095ba17ce6ad3af (sh: Fix occasional FPU register corruption under preempt). Signed-off-by: Adrian Bunk <adrian.bunk@movial.fi> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
