riscv: defconfig: Enable CONFIG_CLK_SOPHGO_CV1800 (2024-05-13 14:26:34 -0700)
----------------------------------------------------------------
RISC-V Patches for the 6.10 Merge Window, Part 1
* Support for byte/half-word compare-and-exchange, emulated via LR/SC
loops.
* Support for Rust.
* Support for Zihintpause in hwprobe.
* Support for the PR_RISCV_SET_ICACHE_FLUSH_CTX prctl().
* Support for lockless lockrefs.
----------------------------------------------------------------
This was really meant to be last week's PR, but due to a handful of small
issues. There's a pair of driver build fixes that are already on the lists and
a report of a ftrace failure that might be triggered by the ftrace/AIA fix, but
seems like we're better off with these than without. I've got a few other
smaller things queued up for Friday, but I figured it'd be best to get this
moving because there's a handful of merge conflicts.
This first one isn't showing up in a in-flight merge `git diff`, but it looks
pretty straight-forward

There's also one in the IMSIC driver where there's really no way for git to
pick up the conflict, as it's a far-away API change. Here's my resolution,

I think this is actually the wrong resolution, and the \ should be kept
as it was added as a fix in commit 01848eee20c6 ("docs: rust: fix improper
rendering in Arch Support page").

Conor.

I am confused.
This commit was applied two months ago by myself,
and it already existed in the mainline.
After this pull request, I do not see no such a commit
applied by Palmer.
Why did this show up in 'git request-pull' ?
The following is the commit in question.
commit 0316e4b04e0156633df7474bae8e8b0791ce028f
Author: Masahiro Yamada <[email protected]>
AuthorDate: Sat Mar 23 18:06:15 2024 +0900

export.h: remove include/asm-generic/export.h
Commit 3a6dd5f614a1 ("riscv: remove unneeded #include
<asm-generic/export.h>") removed the last use of
include/asm-generic/export.h.
This deprecated header can go away.

OK, thanks.
I think I was misunderstanding the effect of "git log -- <path>"
When "-- include/asm-generic" is passed, 36d37f11f555 is hidden.
$ git log --oneline --author=Masahiro | grep include/asm-generic/export.h
0316e4b04e01 export.h: remove include/asm-generic/export.h
36d37f11f555 export.h: remove include/asm-generic/export.h
$ git log --oneline --author=Masahiro -- include/asm-generic/ | grep
include/asm-generic/export.h
0316e4b04e01 export.h: remove include/asm-generic/export.h
"man git-log" explains why:
<path>...
Show only commits that are enough to explain how the files that match the
specified paths came to be. See History Simplification below for details
