amd64: add atomic_fcmpset
==
sparc64: add atomic_fcmpset
==
Implement atomic_fcmpset_* for arm and arm64.
==
Add atomic_fcmpset_*() inlines for powerpc
Summary: atomic_fcmpset_*() is analogous to atomic_cmpset(), but saves off the read value from the target memory location into the 'old' pointer in the case of failure.
==
i386: add atomic_fcmpset
==
Don't retry a lost reservation in atomic_fcmpset()
The desired behavior of atomic_fcmpset_() is to always exit on error. Instead of retrying on lost reservation, leave the retry to the caller, and return

Add atomic_fcmpset_*() inlines for MIPS
atomic_fcmpset_*() is analogous to atomic_cmpset(), but saves off the read value from the target memory location into the 'old' pointer.

i386: fixup fcmpset
An incorrect output specifier was used which worked with clang by accident, but breaks with the in-tree gcc version.
While here plug a whitespace nit.
==
Implement atomic_fcmpset_*() for RISC-V.
==
Use 64bit store instruction in atomic_fcmpset_64.
