Subject: [PATCH 3/5] locking/atomic: centralize generated headers
The generated atomic headers are only intended to be included directly
by <linux/atomic.h>, but are spread across include/linux/ and
include/asm-generic/, where people mnay be encouraged to include them.
This patch centralizes them under include/linux/atomic/.
Other than the header guards and hashes, there is no change to any of
the generated headers as a result of this patch.
