SH never really supported a.out, so this was all just copied over blindly
from x86 way back when. As we don't reference linux/a.out.h anywhere in
the tree, these can now safely be killed off.

We haven't called in to __do_IRQ() in a long time, so it seems like a
reasonable time to switch this on by default.

Presently the NUMA node data isn't saved on kexec. This implements a
simple arch_crash_save_vmcoreinfo() for saving off the relevant data.

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.

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.

(20072fd0c93349e19527dd2fa9588b4335960e62 lost most of its changes
somehow, came from a mbox archive applied with git-am. No idea
what happened. This puts back the missing bits. --rmk)
The initial patch from Lothar, and Lennert make it into a cleaner
one, modified and tested on PXA320 by Eric Miao.
This patch moves the L2 cache operations out of proc-xsc3.S into
dedicated outer cache support code.
CACHE_XSC3L2 can be deselected so no L2 cache specific code will be
linked in, and that L2 enable bit will not be set, this applies to
the following cases:
a. _only_ PXA300/PXA310 support included and no L2 cache wanted
b. PXA320 support included, but want L2 be disabled
So the enabling of L2 depends on two things:
- CACHE_XSC3L2 is selected
- and L2 cache is present
Where the latter is only a safeguard (previous testing shows it works
OK even when this bit is turned on).
IXP series of processors with XScale3 cannot disable L2 cache for the
moment since they depend on the L2 cache for its coherent memory, so
IXP may always select CACHE_XSC3L2.
Other L2 relevant bits are always turned on (i.e. the original code
enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side
effects. Specifically, these bits are:
- OC bits in TTBASE register (table walk outer cache attributes)
- LLR Outer Cache Attributes (OC) in Auxiliary Control Register

That's the userland thread register, so we should never try to change
it like this.
Based upon glibc bug nptl/6577 and suggestions by Jakub Jelinek.

The story is that what we used to do when we actually used
smp_report_regs() is that if you specifically only wanted to have the
current cpu's registers dumped you would call "__show_regs()"
otherwise you would call show_regs() which also invoked
smp_report_regs().
Now that we killed off smp_report_regs() there is no longer any
reason to have these two routines, just show_regs() is sufficient.
Also kill off a stray declaration of show_regs() in sparc64_ksym.c

Some of them use 'bool' and whatnot and therefore are not
kosher for userspace, so don't export them there.

All the call sites are #if 0'd out and we have a much more
useful global cpu dumping facility these days. smp_report_regs()
is way too verbose to be usable.

It just clutters everything up and even though I wrote that hack I
can't remember having used it in the last 5 years or so.

We already have code that does this, but it is only currently attached
to sysrq-'y'.

Record one more level of stack frame program counter.
Particularly when lockdep and all sorts of spinlock debugging is
enabled, figuring out the caller of spin_lock() is difficult when the
cpu is stuck on the lock.

Correct sparc64's implementation of FUTEX_OP_ANDN to do a
bitwise negate of the oparg parameter before applying the
AND operation. All other archs that support FUTEX_OP_ANDN
either negate oparg explicitly (frv, ia64, mips, sh, x86),
or do so indirectly by using an and-not instruction (powerpc).
Since sparc64 has and-not, I chose to use that solution.
I've not found any use of FUTEX_OP_ANDN in glibc so the
impact of this bug is probably minor. But other user-space
components may try to use it so it should still get fixed.
