2009-10-27sh: Clean up more superfluous symbol exports.Paul Mundt
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 <lethal@linux-sh.org>
2009-10-27sh64: cache flush symbol exports.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 <lethal@linux-sh.org>

2009-07-27sh: wire up clear_user_highpage() for sh4, convert sh7705.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.

2009-07-11sh: Use DECLARE_EXPORT() for mcount symbol export.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 <lethal@linux-sh.org>
2009-07-11sh: Decouple mcount from ftrace.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 <lethal@linux-sh.org>
2009-05-22sh: irq: Convert from irq_desc[] to irq_to_desc().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 support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-03sh: remove obsolete no_irq_typeThomas Gleixner

2008-12-22sh: More movmem alias symbol exports for older compilers.Paul Mundt

2008-12-22sh: Add exports for __udivsi3/__sdivsi3 and the _i4 versions.Paul Mundt
Needed by older compilers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Migrate necessary libgcc bits in to arch/sh/lib for SUPERH32.Paul Mundt
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 <lethal@linux-sh.org>
2008-10-31sh: FTRACE renamed to FUNCTION_TRACER.Paul Mundt

2008-10-28sh: Fix FPU tuning on toolchains with mismatched multilib targets.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<cpu-family> 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 <lethal@linux-sh.org>
2008-09-21sh: ftrace support.Paul Mundt
This adds support for ftrace to SH. This only includes CONFIG_FTRACE, and does not handle dynamic ftrace presently. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-04-17Generic semaphore implementationMatthew Wilcox
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.
