| * | MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC. | David Daney | 2009-09-17 | 1 | -17/+17 |
| | | | | | | | | | | | | | | | | | | On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.

| | | | | | | | | This is useful for IDT RC32332, RC32334 and NEC VR5500 processors which do not implement the full MIPS32 / MIPS64 architecture. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> | ||||
