2012-09-18sh: Fix up TIF_NOTIFY_RESUME sans TIF_SIGPENDING handling.Al Viro
As Al notes, we missed a TIF_NOTIFY_RESUME check which caused any handlers without TIF_SIGPENDING also set to skip the notification: Looks like while it is in the relevant masks *and* checked in do_notify_resume() both on 32bit and 64bit variants since commit ab99c733ae73cce31f2a2434f7099564e5a73d95 ("sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.") they are actually *not* reached without simulataneous SIGPENDING, since the actual glue in the callers had not been updated back then and still checks for _TIF_SIGPENDING alone when deciding whether to hit do_notify_resume() or not.

2012-06-13sh: use the new generic strnlen_user() functionPaul Mundt
This discards both the _32 and _64 versions in favour of the consolidated generic one. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-06-13sh: switch to generic strncpy_from_user().Paul Mundt
This kills off the special sh32/64 versions and adopts the generic version. It should be possible to optimize this for SH-4A unaligned loads, but this is a corner case that can be supported incrementally. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-14sh64: Invert page fault fast-path error path values.Paul Mundt
This brings the sh64 version in line with the sh32 one with regards to how errors are handled. Base work for further unification of the implementations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-14sh64: Utilize thread fault code encoding.Paul Mundt
This plugs in fault code encoding for the sh64 page fault, too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-19sh64: Fixup build breakage from breakpoint handler rename.Paul Mundt
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>
2010-01-19sh64: Use the shared FPU state restorer.Paul Mundt
This kills off the sh64-specific state restorer and switches over to the generic one. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-14sh: TS_RESTORE_SIGMASK conversion.Paul Mundt
Replace TIF_RESTORE_SIGMASK with TS_RESTORE_SIGMASK and define our own set_restore_sigmask() function. This saves the costly SMP-safe set_bit operation, which we do not need for the sigmask flag since TIF_SIGPENDING always has to be set too. Based on the x86 and powerpc change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-08sh: Kill off sh64's hand-rolled syscall tracer.Paul Mundt
This is no longer necessary, as there are now sufficient generic alternatives available. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-07sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt
Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-27sh: Use __INIT macro instead of .text.init.Tim Abbott
The sh architecture has some code in the .text.init section, but it does not reference that section in its linker scripts. This change moves this code from the .text.init section to the .init.text section, which is presumably where it belongs.

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>

2008-07-29sh: migrate to arch/sh/include/Paul Mundt
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
