[PATCH] rust: kbuild: rebuild if `.clippy.toml` changes

by Miguel Ojeda

We rarely modify `.clippy.toml`, but currently we do not rebuild if that happens, thus it is easy to miss possible changes in lints. Thus rebuild in case of changes.

[PATCH] arm64: dts: rockchip: Add missing SFC power-domains to rk3576

by Sebastian Reichel

Add the power-domains for the RK3576 SFC nodes according to the TRM part 1. This fixes potential SErrors when accessing the SFC registers without other peripherals (e.g. eMMC) doing a prior power-domain enable. For example this is easy to trigger on the Rock 4D, which enables the SFC0 interface, but does not enable the eMMC interface at the moment. Cc: stable(a)vger.kernel.org Fixes: 36299757129c8 ("arm64: dts: rockchip: Add SFC nodes for rk3576") Signed-off-by: Sebastian Reichel <sebastian.reichel(a)collabora.com> --- I finally managed to get some RK3576 boards integrated to our CI pipeline and promptly got some SError on Rock 4D with the extra test coverage :( As we hope to get some of those boards for KernelCI, it would be good to get this fixed in all affected trees. It seemed enough to just describe the power-domain in DT (i.e. that fixed the SError for the arm64 defconfig when booting the Rock 4D). If we see further problems (I haven't so far), we might need something like [0] for the FSPI driver.

[PATCH 6.6/6.1 ] hwpoison, memory_hotplug: lock folio before unmap hwpoisoned folio

by Xiangyu Chen

From: Ma Wupeng <mawupeng1(a)huawei.com> commit af288a426c3e3552b62595c6138ec6371a17dbba upstream. Commit b15c87263a69 ("hwpoison, memory_hotplug: allow hwpoisoned pages to be offlined) add page poison checks in do_migrate_range in order to make offline hwpoisoned page possible by introducing isolate_lru_page and try_to_unmap for hwpoisoned page.
