| * sh64: fix tracing of signals.Paul Mundt2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows the parisc change to ensure that tracehook_signal_handler() is aware of when we are single-stepping in order to ptrace_notify() appropriately. While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh64: Fixup build breakage from breakpoint handler rename.Paul Mundt2010-01-19
| | | | | | | | | | | | | | The breakpoint handler was renamed on sh32, but sh64 was overlooked in the conversion. Fix it up now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh64: Use the shared FPU state restorer.Paul Mundt2010-01-19
| | | | | | | | | | | | | | This kills off the sh64-specific state restorer and switches over to the generic one. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh64: Fix up the build for the thread_xstate changes.Paul Mundt2010-01-19
|/ | | | | | | This updates the sh64 processor info with the sh32 changes in order to tie in to the generic task_xstate management code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up FPU build for SH5Matt Fleming2009-12-14
| | | | | | | | After the recent FPU optimisation commit the signature of save_fpu() changed. "regs" wasn't used in the implementation of save_fpu() anyway. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Wire up HAVE_SYSCALL_TRACEPOINTS.Paul Mundt2009-09-16
| | | | | | | | This is necessary to get ftrace syscall tracing working again.. a fairly trivial and mechanical change. The one benefit is that this can also be enabled on sh64, despite not having its own ftrace port. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following compile error caused by commit c459dbf294b4a3d70490a468a7ca3907fb2c2f57 (sh: ptrace single stepping cleanups.): <-- snip --> ...

* sh: Fix up the audit arch endian specification.Paul Mundt2008-08-01
| | | | | | | | 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>
* sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.Paul Mundt2008-08-01
| | | | | | | | | | | | | | 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>
* 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>
* sh64: add missing #include <asm/fpu.h>'sAdrian Bunk2008-04-15
| | | | | | | | | | 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).
