Documentation: arch-support: remove obsolete architectures

2018-03-26T13:56:10Z

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.

xtensa: add support for KASAN

2017-12-17T06:37:12Z

Cover kernel addresses above 0x90000000 by the shadow map. Enable HAVE_ARCH_KASAN when MMU is enabled. Provide kasan_early_init that fills shadow map with writable copies of kasan_zero_page. Call kasan_early_init right after mmu initialization in the setup_arch. Provide kasan_init that allocates proper shadow map pages from the memblock and puts these pages into the shadow map for addresses from VMALLOC area to the end of KSEG. Call kasan_init right after memblock initialization. Don't use KASAN for the boot code, MMU and KASAN initialization and page fault handler. Make kernel stack size 4 times larger when KASAN is enabled to avoid stack overflows. GCC 7.3, 8 or newer is required to build the xtensa kernel with KASAN. Signed-off-by: Max Filippov
