• 64711f9a4   xtensa: implement jump_label support ... Browse Code »

  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.

  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'.

• 1ea5afd42   Documentation: arch-support: remove obsolete architectures ... Browse Code »

  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:
