lib: Add self-test for atomic64_t This patch adds self-test on boot code for atomic64_t. This has been used to test the later changes in this patchset.

bug.h: add include of it to various implicit C users With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

x86, atomic64: In selftest, distinguish x86-64 from 586+ The x86-64 implementation of the atomics is totally different from the i586+ implementation, which makes it quite confusing to call it "586+". Also fix indentation, and add "i" for "i386" and "i586" as used elsewhere in the kernel. Signed-off-by: H.
