ARM: 9158/1: leave it to core code to manage thread_info::cpu

2021-12-17T11:34:31+00:00

Since commit bcf9033e5449 ("sched: move CPU field back into thread_info
if THREAD_INFO_IN_TASK=y"), the CPU field in thread_info went back to
being managed by the core code, so we no longer have to keep it in sync
in arch code.

While at it, mark THREAD_INFO_IN_TASK as done for ARM in the
documentation.

parisc: Move thread_info into task struct

2021-11-01T06:35:59+00:00

This implements the CONFIG_THREAD_INFO_IN_TASK option.

With this change:
- before thread_info was part of the stack and located at the beginning of the stack
- now the thread_info struct is moved and located inside the task_struct structure
- the stack is allocated and handled like the major other platforms
- drop the cpu field of thread_info and use instead the one in task_struct

arch: remove unicore32 port

2020-07-01T09:09:13+00:00

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.

Documentation/features: Refresh the arch support status files

2020-05-25T16:17:11+00:00

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.
