* sh: ptrace single stepping cleanups.Paul Mundt2008-08-01
| | | | | | | | This converts the single stepping done by sh/sh64 ptrace implementations to use the generic user_enable/disable_single_step(), and subsequently rips out a lot of ptrace request cases that are now handled generically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: seccomp support.Paul Mundt2008-08-01
| | | | | | | This hooks up the seccomp thread flag and associated callback from the syscall tracer. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* kdump: sh: parse elfcorehdr command line argumentSimon Horman2008-08-01
| | | | | | | | | | | | A quick cut and paste from other architectures to allow SH to parse the elfcorehdr command line argument which is required for both is_kdump_kernel() and vmcore to function. (the former is as yet unused on SH). Tested compilation only Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Make sure AT_SYSINFO_EHDR is exposed to userspace in asm/auxvec.h.Paul Mundt2008-07-29
| | | | | | | | | | | | | | | | | | Presently this is protected by a CONFIG_VSYSCALL ifdef so we don't inadvertently trigger the creation of the gate VMA on CPUs where we don't enable the vDSO, which is obviously not visible to userspace. Fix this up by adding in an ifndef __KERNEL__ check at the same time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
