f22ab814a2
This patch contains the following cleanups for the asm/ptrace.h
userspace headers:
- include/asm-generic/Kbuild.asm already lists ptrace.h, remove
the superfluous listings in the Kbuild files of the following
architectures:
- cris
- frv
- powerpc
- x86
- don't expose function prototypes and macros to userspace:
- arm
- blackfin
- cris
- mn10300
- parisc
- remove #ifdef CONFIG_'s around #define's:
- blackfin
- m68knommu
- sh: AFAIK __SH5__ should work in both kernel and userspace,
no need to leak CONFIG_SUPERH64 to userspace
- xtensa: cosmetical change to remove empty
#ifndef __ASSEMBLY__ #else #endif
from the userspace headers
Not changed by this patch is the fact that the following architectures
have a different struct pt_regs depending on CONFIG_ variables:
- h8300
- m68knommu
- mips
This does not work in userspace.
