* sparc64: switch to generic kernel_thread()Al Viro2012-10-141-3/+8

* sparc64: clear syscall_noerror on the entry to syscall, not on the exitAl Viro2012-10-141-1/+0
| | | | | | | | | Move that sucker to just before TI_FPDEPTH and replace stb with sth in etrap_save(). Take current_ds to its old place, so that we don't push wsaved into TI_... flags. That allows to lose clearing syscall_noerror on return from syscall. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* sparc64: fix ptrace interaction with force_successful_syscall_return()Al Viro2012-10-101-18/+14
| | | | | | | | | we want syscall_trace_leave() called on exit from any syscall; skipping its call in case we'd done force_successful_syscall_return() is broken... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Kill off old sys_perfctr system call and state.David S. Miller2010-03-031-21/+2
| | | | | | | | People should be using the perf events interfaces, and the way these system call facilities used the %pcr conflicts with the usage of the NMI watchdog and perf events. Signed-off-by: David S. Miller <davem@davemloft.net>

* [CVE-2009-0029] Remove __attribute__((weak)) from sys_pipe/sys_pipe2Heiko Carstens2009-01-141-1/+1
| | | | | | | | | | | | | Remove __attribute__((weak)) from common code sys_pipe implemantation. IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations with the same name. Just rename them. For sys_pipe2 there is no architecture specific implementation. Cc: Richard Henderson <rth@twiddle.net> Cc: David S.

* sparc,sparc64: unify kernel/Sam Ravnborg2008-12-041-0/+279
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.
