There is no reason we can't make the saved fp registers the same for all m68k types and ColdFire. There is a little wasted space, but the code consistency and cleanliness is a big win. sigcontext.h is an exported header, but currently there is no in-mainline users of the !__uClinux__ and __mcoldfire__ case that this change effects. Even better this change actually makes this structure consistent with the out-of-mainline ColdFire/MMU code.

LibSegFault uses piggybacks sc_fpstate field of the `struct sigcontext' and this patch avoids LibSegFault overflowing this field. Also this removes an unnecessary divergence from classic m68k.

The following patch defines sigcontext ABI of ColdFire. Due to ISA restrictions ColdFire needs different rt_sigreturn trampoline. And due to ColdFire FP registers being 8-bytes instead of 12-bytes on m68k, sigcontext and fpregset structures should be updated. Regarding the sc_fpstate[16+6*8] field, it would've been enough 16 bytes to store ColdFire's FP state. To accomodate GLIBC's libSegFault it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered FP registers). I set it to 16+6*8 to provide some extra space for any future changes in the ColdFire FPU.

It is trivial to merge the non-MMU and MMU versions of sigcontext.h. Without a single file "make headers_install" is broken for m68k (since each of the sub-varients of sigconext.h are not installed). Signed-off-by: NGreg Ungerer <gerg@uclinux.org>

Merge header files for m68k and m68knommu to the single location: arch/m68k/include/asm The majority of this patch was the result of the script that is included in the changelog below. The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named <file>_mm.h [mm for memory manager] The m68knommu file is named <file>_no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.
