Subject: [PATCH 00/10] timers/cpuidle: Fixes and cleanups
Date: Fri, 11 Aug 2023 19:00:39 +0200	[thread overview]
Message-ID: <20230811170049.308866-1-frederic@kernel.org> (raw)

Hi,

The first part of the series is cpuidle callback fixes against timers,
some of which haven't been Signed by Peter yet.

Another part is removing the overhead of useless TIF_NR_POLLING clearing.

The rest is comments.

HEAD: b66dd12bb29cca558b9323f2b270a7dae8f56c48

Thanks,
	Frederic
