lib/atomic64_test.c: add a test that atomic64_inc_not_zero() returns an int
atomic64_inc_not_zero() returns a "truth value" which in C is traditionally an int. That means callers are likely to expect the result will fit in an int.
If an implementation returns a "true" value which does not fit in an int, then there's a possibility that callers will truncate it when they store it in an int.
In fact this happened in practice, see commit 966d2b04e070 ("percpu-refcount: fix reference leak during percpu-atomic transition").
So add a test that the result fits in an int, even when the input doesn't. This catches the case where an implementation just passes the non-zero input value out as the result.

atomic64: no need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
This came to light when implementing native 64-bit atomics for ARCv2.
The atomic64 self-test code uses CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE to check whether atomic64_dec_if_positive() is available. It seems it was needed when not every arch defined it. However as of current code the Kconfig option seems needless
- for CONFIG_GENERIC_ATOMIC64 it is auto-enabled in lib/Kconfig and a generic definition of API is present lib/atomic64.c - arches with native 64-bit atomics select it in arch/*/Kconfig and define the API in their headers
So I see no point in keeping the Kconfig option
Compile tested for: - blackfin (CONFIG_GENERIC_ATOMIC64) - x86 (!CONFIG_GENERIC_ATOMIC64) - ia64

x86/headers: Don't include asm/processor.h in asm/atomic.h
asm/atomic.h doesn't really need asm/processor.h anymore. Everything it uses has moved to other header files. So remove that include.
processor.h is a nasty header that includes lots of other headers and makes it prone to include loops. Removing the include here makes asm/atomic.h a "leaf" header that can be safely included in most other headers.
The only fallout is in the lib/atomic tester which relied on this implicit include. Give it an explicit include. (the include is in ifdef because the user is also in ifdef)

x86, atomic64: In selftest, distinguish x86-64 from 586+

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.
