[PATCH v5 01/27] kvm: stop including asm-generic/bitops/le.h directly

From: Akinobu Mita <akinobu.mita@gmail.com>
Date: 2011-01-22 13:13:26
Also in: kvm, lkml
Subsystem: kernel virtual machine (kvm), the rest · Maintainers: Paolo Bonzini, Linus Torvalds

asm-generic/bitops/le.h is only intended to be included directly from
asm-generic/bitops/ext2-non-atomic.h or asm-generic/bitops/minix-le.h
which implements generic ext2 or minix bit operations.

This stops including asm-generic/bitops/le.h directly and use ext2
non-atomic bit operations instead.

It seems odd to use ext2_set_bit() on kvm, but it will replaced with
__set_bit_le() after introducing little endian bit operations
for all architectures.  This indirect step is necessary to maintain
bisectability for some architectures which have their own little-endian
bit operations.
