UAPI: Place comments in empty arch Kbuilds to make them non-empty Place comments in: arch/mips/include/asm/Kbuild arch/tile/include/arch/Kbuild to make them non-empty so that the patch program doesn't remove them when it reduces them to nothing. Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.

# MIPS headers
mips: generate uapi header and system call table files System call table generation script must be run to gener- ate unistd_(nr_)n64/n32/o32.h and syscall_table_32_o32/ 64_n64/64_n32/64-o32.h files. This patch will have changes which will invokes the script. This patch will generate unistd_(nr_)n64/n32/o32.h and syscall_table_32_o32/64_n64/64-n32/64-o32.h files by the syscall table generation script invoked by parisc/Make- file and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/scall32-o32/64-n64/64-n32/- 64-o32.Sfile.

MIPS: Use queued read/write locks (qrwlock) This patch switches MIPS to make use of generically implemented queued read/write locks, rather than the custom implementation used previously. This allows us to drop a whole load of inline assembly, share more generic code, and is also a performance win. Results from running the AIM7 short workload on a MIPS Creator Ci40 (ie. 2 core 2 thread interAptiv CPU clocked at 546MHz) with v4.12-rc4 pistachio_defconfig, with ftrace disabled due to a current bug, and both with & without use of queued rwlocks & spinlocks: Forks | v4.12-rc4 | +qlocks | Change -------|-----------|----------|-------- 10 | 52630.32 | 53316.31 | +1.01% 20 | 51777.80 | 52623.15 | +1.02% 30 | 51645.92 | 52517.26 | +1.02% 40 | 51634.88 | 52419.89 | +1.02% 50 | 51506.75 | 52307.81 | +1.02% 60 | 51500.74 | 52322.72 | +1.02% 70 | 51434.81 | 52288.60 | +1.02% 80 | 51423.22 | 52434.85 | +1.02% 90 | 51428.65 | 52410.10 | +1.02% The kernels used for these tests also had my "MIPS: Hardcode cpu_has_* where known at compile time due to ISA" patch applied, which allows the kernel_uses_llsc checks in cmpxchg() & xchg() to be optimised away at compile time.

MIPS: Remove asm/user.h The struct user definition in this file is not used anywhere (the ELF core dumper does not use that format). Therefore, remove the header and instead enable the asm-generic user.h which is an empty header to satisfy a few generic headers which still try to include user.h.
