There are other places where we want to have access to the trap/exception
number, so move out the lookup_exception_vector() helper. While we're at
it, refactor it slightly to return the vector instead.

This follows the powerpc commit f6a616800e68b61807d0f7bb0d5dc70665ef8046
'[POWERPC] Fix kernel stack allocation alignment'.
SH has traditionally forced the thread order to be relative to the page
size, so there were never any situations where the same bug was
triggered by slub. Regardless, the usage of > 8kB stacks for the larger
page sizes is overkill, so we switch to using slab allocations there,
as per the powerpc change.

linux/mmzone.h isn't exported, kill it off from asm/setup.h and simply
deal with it in the places that have a dependency instead.

These have been using overrides for ELF_CORE_COPY_TASK_REGS and
ELF_CORE_COPY_FPREGS while the generic versions can be used instead.
Presently the pt_regs are also duplicated across elf_core_copy_regs()
and elf_core_copy_task_regs(), this switches to simply copying out
through elf_core_copy_regs() instead.

Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control
page is used for not only code on some platform. For example in kexec
jump, it is used for data and stack too.

Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h
This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h),
but, I'd like to add sh2a specific file here, because
1. the values defined there are not suitable for sh2a.
2. I don't think there is "common" definition for these values.
Values are chosen by consideration of followings...
P1 is 0. perhaps no question.
P2 is from hardware manual, which says no-cache area starts at 20000000.
It means that P? space size=20000000.
P3 is P2+size since asm/ptrace.h uses P3 as a end of P2.
P4 is P3+size since asm/fixup.h uses P4 as a end of P3.

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

This follows the changes in commits:

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.

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.

Presently this is protected by a CONFIG_VSYSCALL ifdef so we don't
inadvertently trigger the creation of the gate VMA on CPUs where we don't
enable the vDSO, which is obviously not visible to userspace. Fix this up
by adding in an ifndef __KERNEL__ check at the same time.
