After the last architecture switched to generic hard irqs the config

for !CONFIG_GENERIC_HARDIRQS can be removed.

Several architectures have similar stack debugging config options.
They all pretty much do the same thing, some with slightly
differing help text.
This patch changes the architectures to instead enable a Kconfig
boolean, and then use that boolean in the generic Kconfig.debug
to present the actual menu option. This removes a bunch of
duplication and adds consistency across arches.

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

Add OProfile support for metag, using the perf backend, and falling back
to generic timer based sampling if perf counter interrupt support is
disabled.
The oprofile code prepends "metag/" to the perf pmu name to give
"metag/meta2" which is more consistent with other oprofile arch names.
The backtrace code makes use of <asm/stacktrace.h> for kernel
backtracing, and a simple frame pointer walk for userland backtracing.

We have CONFIG_SYMBOL_PREFIX, which three archs define to the string
"_". But Al Viro broke this in "consolidate cond_syscall and
SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to
do so.
Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to
prefix it so something. So various places define helpers which are
defined to nothing if CONFIG_SYMBOL_PREFIX isn't set:
1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX.
2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym)
3) include/linux/export.h defines MODULE_SYMBOL_PREFIX.
4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7)
5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym)
6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX
7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if
CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version
for pasting.
(arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too).
Let's solve this properly:
1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX.
2) Make linux/export.h usable from asm.
3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().
4) Make everyone use them.
