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: Retire kvm paravirt paravirt machine was introduced for Cavium's partial virtualization technology, however, it's host side support and QEMU support never landed in upstream. As Cavium was acquired by Marvel and they have no intention to maintain their MIPS product line, also paravirt is unlikely to be utilized by community users, it's time to retire it if nobody steps in to maintain it.

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.
