* Documentation: arch-support: remove obsolete architecturesArnd Bergmann2018-03-261-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Documentation/features/vm: Meta2 is capable of THPJames Hogan2015-09-071-1/+1
| | | | | | | | | | | | | Change metag Transparent Huge Pages (THP) support from .. to TODO. Meta2 has variable sized pages, between 4KB and 4MB, specified at the 1st level page table level, and already supports hugetlbfs, so supporting THP is theoretically possible too.
