2009-01-21sh: export the sh7343 JPU to user spaceMagnus Damm
This patch exports the sh7343 JPU to user space using uio_pdrv_genirq, very similar to the sh7722 JPU patch by Hayama-san. While at it fix up the end of the sh7722 JPU iomem resource. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: add UIO support for JPU on SH7722.Takanari Hayama

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>
