Documentation/features: Use loongarch instead of loong

2022-12-05T09:50:12+00:00

The official arch name is LoongArch [1], we should use small letter
loongarch instead of loong in Documentation/features, just use the
features-refresh.sh to refresh all the related files.

Documentation/features: Update the arch support status files

2022-06-09T15:35:57+00:00

The arch support status files don't match reality as of v5.19-rc1,
use the features-refresh.sh to refresh all the arch-support.txt files
in place.  The main effect is to add entries for the new loong
architecture.

Merge branch 'remove-h8300' of git://git.infradead.org/users/hch/misc into asm-generic

2022-04-04T12:42:49+00:00

* 'remove-h8300' of git://git.infradead.org/users/hch/misc:
  remove the h8300 architecture

This is clearly the least actively maintained architecture we have at
the moment, and probably the least useful. It is now the only one that
does not support MMUs at all, and most of the boards only support 4MB
of RAM, out of which the defconfig kernel needs more than half just
for .text/.data.

Guenter Roeck did the original patch to remove the architecture in 2013
after it had already been obsolete for a while, and Yoshinori Sato brought
it back in a much more modern form in 2015. Looking at the git history
since the reinstantiation, it's clear that almost all commits in the tree
are build fixes or cross-architecture cleanups:

nds32: Remove the architecture

2022-03-07T12:54:59+00:00

The nds32 architecture, also known as AndeStar V3, is a custom 32-bit
RISC target designed by Andes Technologies. Support was added to the
kernel in 2016 as the replacement RISC-V based V5 processors were
already announced, and maintained by (current or former) Andes
employees.

As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.

While the port is still in a reasonably good shape, it only gets
worse over time without active maintainers, so it seems best
to remove it before it becomes unusable. As always, if it turns
out that there are mainline users after all, and they volunteer
to maintain the port in the future, the removal can be reverted.

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.
