Additional fixes for processors without ISA_DSP_LEVEL2.
sigcontext_t does not have dummy_acc1h, dummy_acc1l members any longer.
This patch is against v2.6.19.1 kernel.

Subject: [PATCH 2.6.19] m32r: Make userspace headers platform-independent
Date: Wed, 06 Dec 2006 19:00:01 +0900
> The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa
> configuration" for userspace application programs, such as glibc, gdb, etc.
>
> This is because the recent kernel do not include linux/config.h not to
> expose kernel headers for userspace.
>
> To fix the above compile errors, this patch fixes two headers ptrace.h
> and sigcontext.h for m32r and makes them platform-independent.
