c3b4adfa65 sh: Save NUMA node data in vmcore for crash dumps.
Presently the NUMA node data isn't saved on kexec. This implements a
simple arch_crash_save_vmcoreinfo() for saving off the relevant data.

4b59c97325 sh: module_alloc() should be using vmalloc_exec().
SH-X2 extended mode TLB allows for toggling of the exec bit, so make
sure we are using the right protection bits for module space there
also.

9e5e21170e sh: Fix up the audit arch endian specification.
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.

ab99c733ae sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.
This follows the changes in commits:

7d6d637dac
4f72c4279e

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.

c459dbf294 sh: ptrace single stepping cleanups.
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.

daf423db3b kdump: sh: parse elfcorehdr command line argument
A quick cut and paste from other architectures to allow SH
to parse the elfcorehdr command line argument which is required
for both is_kdump_kernel() and vmcore to function.
(the former is as yet unused on SH).

Tested compilation only

0b1689cfbb sh: Don't miss pending signals returning to user mode after signal processing
Without this patch, signals sent during architecture specific signal
handling (typically as a result of the user's stack being inaccessible)
are ignored.

This is the SH version of commit c3ff8ec31c

1312994c80 sh: Merge sh7343 and sh7722 clock code
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. SIU clocks are disabled on sh7343 for now.

With this change all SuperH Mobile devices now use the same clock code.
