2020-07-01arch: remove unicore32 portMike Rapoport
The unicore32 port do not seem maintained for a long time now, there is no upstream toolchain that can create unicore32 binaries and all the links to prebuilt toolchains for unicore32 are dead. Even compilers that were available are not supported by the kernel anymore. Guenter Roeck says: I have stopped building unicore32 images since v4.19 since there is no available compiler that is still supported by the kernel. I am surprised that support for it has not been removed from the kernel. Remove unicore32 port.

2020-05-25Documentation/features: Refresh the arch support status filesBjörn Töpel
I was manually editing the arch-support.txt for eBPF-JIT, when I realized the refresh script [1] has not been run for a while. Let's fix that, so that the entries are more up-to-date.

2019-07-30Documentation/features/locking: update listsMark Rutland
The locking feature lists don't match reality as of v5.3-rc1: * arm64 moved to queued spinlocks in commit: c11090474d70590170cf5fa6afe85864ab494b37 ("arm64: locking: Replace ticket lock implementation with qspinlock") * xtensa moved to queued spinlocks and rwlocks in commit: 579afe866f52adcd921272a224ab36733051059c ("xtensa: use generic spinlock/rwlock implementation") * architecture-specific rwsem support was removed in commit: 46ad0840b1584b92b5ff2cc3ed0b011dd6b8e0f1 ("locking/rwsem: Remove arch specific rwsem files") So update the feature lists accordingly, and remove the now redundant rwsem-optimized list.

2018-05-08Documentation/features/locking: Use '!RWSEM_GENERIC_SPINLOCK' as Kconfig for ↵Andrea Parri
'rwsem-optimized' Uses '!RWSEM_GENERIC_SPINLOCK' in place of 'Optimized asm/rwsem.h' as Kconfig for 'rwsem-optimized': the new Kconfig expresses this feature equivalently, while also enabling the script 'features-refresh.sh' to operate on the corresponding arch support status file. Also refreshes the status matrix by using the script 'features-refresh.sh'.

2018-03-26Documentation: arch-support: remove obsolete architecturesArnd Bergmann
A number of architecture ports are obsolete and getting dropped, so we no longer want to track the respective features. We already removed the lines for metag and mn10300, this does the same edits for all the others. For the remaining 21 architectures, this shows how many are known to implement each given feature: 19 time/modern-timekeeping/arch-support.txt 19 time/clockevents/arch-support.txt 15 core/tracehook/arch-support.txt 14 core/generic-idle-thread/arch-support.txt 13 locking/lockdep/arch-support.txt 12 io/dma-api-debug/arch-support.txt 11 debug/kgdb/arch-support.txt 10 time/virt-cpuacct/arch-support.txt 9 debug/kretprobes/arch-support.txt 9 debug/kprobes/arch-support.txt 8 vm/THP/arch-support.txt 8 vm/pte_special/arch-support.txt 8 vm/numa-memblock/arch-support.txt 8 io/sg-chain/arch-support.txt 7 perf/kprobes-event/arch-support.txt 7 locking/rwsem-optimized/arch-support.txt 7 debug/gcov-profile-all/arch-support.txt 7 core/jump-labels/arch-support.txt 7 core/BPF-JIT/arch-support.txt 6 vm/ELF-ASLR/arch-support.txt 6 time/context-tracking/arch-support.txt 6 seccomp/seccomp-filter/arch-support.txt 6 debug/stackprotector/arch-support.txt 5 time/irq-time-acct/arch-support.txt 5 io/dma-contiguous/arch-support.txt 5 debug/uprobes/arch-support.txt 4 vm/ioremap_prot/arch-support.txt 4 time/arch-tick-broadcast/arch-support.txt 4 perf/perf-stackdump/arch-support.txt 4 perf/perf-regs/arch-support.txt 3 debug/KASAN/arch-support.txt 2 vm/PG_uncached/arch-support.txt 2 vm/huge-vmap/arch-support.txt 2 sched/numa-balancing/arch-support.txt 2 sched/membarrier-sync-core/arch-support.txt 2 locking/cmpxchg-local/arch-support.txt 2 debug/optprobes/arch-support.txt 2 debug/kprobes-on-ftrace/arch-support.txt 1 vm/TLB/arch-support.txt 1 locking/queued-spinlocks/arch-support.txt 1 locking/queued-rwlocks/arch-support.txt 1 debug/user-ret-profiler/arch-support.txt 0 lib/strncasecmp/arch-support.txt Note that the list does not include riscv or nds32 yet, these still need to be added.
