2008-07-28sh: Don't miss pending signals returning to user mode after signal processingStuart MENEFY1-1/+1
Without this patch, signals sent during architecture specific signal handling (typically as a result of the user's stack being inaccessible) are ignored.

2008-07-28sh: Show all clocks and their state in /proc/clocksMagnus Damm1-9/+5

2008-07-28sh: Merge sh7343 and sh7722 clock codeMagnus Damm3-130/+41
This code makes sh7343 share the sh7722 clock code. Instead of just using the good and very old sh7343 clock implmentation, switch to the new MSTPCR enabled clock code.

2008-07-28fix sh ptep_get_and_clear breakageAdrian Bunk1-1/+1
Commit 1ea0704e0da65b2b46f9142ff1391163aac24060 (mm: add a ptep_modify_prot transaction abstraction) triggered on sh build errors like the following: <-- snip --> ...

2008-07-28sh: Conditionally re-enable IRQs in fault path.Stuart Menefy2-6/+9
The current kernel behaviour is to reenable interrupts unconditionally when taking a page fault. This patch changes this to only enable them if interrupts were previously enabled. It also fixes a problem seen with this fix in place: the kernel previously flushed the vsyscall page when handling a signal, which is not only unncessary, but caused a possible sleep with interrupts disabled.
