arch: remove unicore32 port

2020-07-01T09:09:13Z

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. Signed-off-by: Mike Rapoport Acked-by: Arnd Bergmann Acked-by: Guenter Roeck

Documentation/features: Refresh the arch support status files

2020-05-25T16:17:11Z

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.

xtensa: implement jump_label support

2018-12-20T22:44:38Z

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. Signed-off-by: Max Filippov

Documentation/features/core: Add arch support status files for 'cBPF-JIT' and 'eBPF-JIT'

2018-05-08T15:28:20Z

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'. Signed-off-by: Andrea Parri Cc: Ingo Molnar Cc: Jonathan Corbet Cc: Andrew Morton Signed-off-by: Jonathan Corbet
