c46acb8e20 fix sh ptep_get_and_clear breakage
Commit 1ea0704e0d
(mm: add a ptep_modify_prot transaction abstraction)
triggered on sh build errors like the following:

<--  snip  -->

...
  CC      arch/sh/mm/pg-sh4.o
cc1: warnings being treated as errors
include2/asm/pgtable.h:139: error: 'ptep_get_and_clear' declared inline after being called
include2/asm/pgtable.h:139: error: previous declaration of 'ptep_get_and_clear' was here
make[2]: *** [arch/sh/mm/pg-sh4.o] Error 1

<--  snip  -->

Since there's no good reason for marking these global functions as
"inline" this patch therefore removes the inline's.

f2fb4e4f64 sh: Conditionally re-enable IRQs in fault path.
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.

9b14ec35f0 binfmt_elf_fdpic: Magical stack pointer index, for NEW_AUX_ENT compat.
While implementing binfmt_elf_fdpic on SH it quickly became apparent
that SH was the first platform to support both binfmt_elf_fdpic and
binfmt_elf, as well as the only of the FDPIC platforms to make use of the
auxvt.

Currently binfmt_elf_fdpic uses a special version of NEW_AUX_ENT() where
the first argument is the entry displacement after csp has been adjusted,
being reset after each adjustment. As we have no ability to sort this out
through the platform's ARCH_DLINFO, this index needs to be managed
entirely in create_elf_fdpic_tables(). Presently none of the platforms
that set their own auxvt entries are able to do so through their
respective ARCH_DLINFOs when using binfmt_elf_fdpic.

In addition to this, binfmt_elf_fdpic has been looking at
DLINFO_ARCH_ITEMS for the number of architecture-specific entries in the
auxvt. This is legacy cruft, and is not defined by any platforms in-tree,
even those that make heavy use of the auxvt. AT_VECTOR_SIZE_ARCH is
always available, and contains the number that is of interest here, so we
switch to using that unconditionally as well.

As this has direct bearing on how much stack is used, platforms that have
configurable (or dynamically adjustable) NEW_AUX_ENT calls need to either
make AT_VECTOR_SIZE_ARCH more fine-grained, or leave it as a worst-case
and live with some lost stack space if those entries aren't pushed (some
platforms may also need to purposely sacrifice some space here for
alignment considerations, as noted in the code -- although not an issue
for any FDPIC-capable platform today).
