Many of these symbols went away completely, or we just never cared about
them in the first place. Trim the exports down to the essential set.Signed-off-by: Paul Mundt

These were previously hidden in sh_ksyms_32, despite also being needed
for sh64 now that the cache.c code is shared.Signed-off-by: Paul Mundt

This wires up clear_user_highpage() on SH-4 and subsequently converts the
SH7705 32kB cache mode over to using it. Now that the SH-4 implementation
handles all of the dcache purging directly in the aliasing case, there is
no need to do this in the default clear_page() implementation.Signed-off-by: Paul Mundt

The function prototype for mcount is not defined if we are not building
with ftrace support enabled, so use DECLARE_EXPORT() to stub one in.Signed-off-by: Paul Mundt
-
This adds a general CONFIG_MCOUNT in order to permit mcount generation
without ftrace support. This is primarily for allowing platforms to
enable aggressive stack overflow checking without having to enable ftrace
support. Based on the sparc64 implementation.Signed-off-by: Paul Mundt

This converts a few places that were using the old irq_desc[] array over
to the shiny new irq_to_desc() helper. Preperatory work for sparse irq

This moves in the necessary libgcc bits for SUPERH32 and drops the
libgcc linking for the regular targets. This in turn allows us to rip
out quite a few hacks both in sh_ksyms_32 and arch/sh/Makefile.Signed-off-by: Paul Mundt

Presently there is very little standing in the way of using an SH-4
toolchain for building an SH-2 kernel, and vice versa. Binutils itself
has no limitations whatsoever and supports explicit ISA hinting, which
we already use with varying degrees of success today.This leaves GCC as the odd one out, due to a rather dubious policy
decision by the GCC folks to not include all of the CPU family variants
in the default list of multilib targets in GCC4. Despite best efforts to
the contrary, libgcc itself already contains awareness of the various CPU
types and remains generally usable, allowing it to safely be referenced
even on a mismatched target (and indeed, explicit ISA tuning by binutils
keeps us honest in terms of ensuring that we do not link incompatible
objects in).In order to support this, a couple of changes had to be made. Firstly,
the introduction of MAYBE_DECLARE_EXPORT(), which provides a __weak
extern reference for libgcc resident routines when finer-grained
-m based tuning is not supported by the toolchain. This
fixes up the __sdivsi3_i4i and __udivsi3_i4i references when dealing
with SH-2 kernels linked with an SH-4 libgcc. Secondly, in case where we
are unable to find a suitable match for CPU family tuning but still
have a toolchain that defaults to FP instruction generation, a suitable
nofpu target must be selected. This is accomplished by selecting the
first nofpu multilib target supported by the toolchain, which is
also necessary for selecting the proper libgcc to link against.Signed-off-by: Paul Mundt

Semaphores are no longer performance-critical, so a generic C
implementation is better for maintainability, debuggability and
extensibility. Thanks to Peter Zijlstra for fixing the lockdep
warning. Thanks to Harvey Harrison for pointing out that the
unlikely() was unnecessary.Signed-off-by: Matthew Wilcox
