2009-04-04sh: Fix up DSP context save/restore.Michael Trimarchi
There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

2008-08-02sh: Fix up the audit arch endian specification.Paul Mundt
Presently this was always being set to AUDIT_ARCH_SH, which assumes big endian. Fix this up so that the architecture actually reflects what we're running on. 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>
2008-08-02sh: ptrace single stepping cleanups.Paul Mundt
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>
2008-08-02sh: seccomp support.Paul Mundt
This hooks up the seccomp thread flag and associated callback from the syscall tracer. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
