Subject: [RFC 04/17] asm-generic: introduce asm/bitsperlong.h
Content-Disposition: inline; filename=0020-define-__BITS_PER_LONG-64-on-all-64-bit-architectu.patch
X-Provags-ID: V01U2FsdGVkX1/jLb8P+uRl1RcCf5V+QdVp81YPPHSqBrYSMpY

This provides a reliable way for asm-generic/types.h and other
files to find out if it is running on a 32 or 64 bit platform.
We cannot use CONFIG_64BIT for this in headers that are included
from user space because CONFIG symbols are not available there.
We also cannot do it inside of asm/types.h because some headers
need the word size but cannot include types.h.
The solution is to introduce a new header <asm/bitsperlong.h>
that defines both __BITS_PER_LONG for user space and
BITS_PER_LONG for usage in the kernel. The asm-generic
version falls back to 32 bit unless the architecture overrides
it, which I did for all 64 bit platforms.

All the m68knommu includes have merged into the m68k includes.
There is no arch/m68knommu/include directory any more.
