xtensa: implement jump_label support2018-12-20T22:44:38ZMax Filippovjcmvbkbc@gmail.com2018-12-20T03:48:37Zurn:sha1:64711f9a47d4defa90417f5e8db8ed0060bc3275
Use 3-byte 'nop' and 'j' instructions that are always present. Don't let
assembler mark a spot right after patchable 'j' instruction as
unreachable and later put literals or padding bytes there. Add separate
implementations of patch_text for SMP and UP cases, avoiding use of
atomics on UP.

Documentation/features/core: Add arch support status files for 'cBPF-JIT' and 'eBPF-JIT'2018-05-08T15:28:20ZAndrea Parriandrea.parri@amarulasolutions.com2018-05-07T10:43:40Zurn:sha1:b466865916d554bbdeaa4d440add7e9e959a5433
Commit 6077776b5908e split 'HAVE_BPF_JIT' into cBPF and eBPF variant.
Adds arch support status files for the new variants, and removes the
status file corresponding to 'HAVE_BPT_JIT'. The new status matrices
were auto-generated using the script 'features-refresh.sh'.

Documentation: arch-support: remove obsolete architectures2018-03-26T13:56:10ZArnd Bergmannarnd@arndb.de2018-03-09T11:02:36Zurn:sha1:1ea5afd42a16058f9301a46c8969787c7baa7eea
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:
