Subject: [PATCH 0/7] x86/mm: Clean up and use temportary_mm more
Date: Tue, 19 Nov 2024 17:25:27 +0100	[thread overview]
Message-ID: <20241119162527.952745944@infradead.org> (raw)

Hi,

These are most of the patches I had in x86/lazy and are the preparatory patches
for x86 to eventually run witn MMU_LAZY_TLB_REFCOUNT=n.

The rebase and submission prompted by Rik's recent context switch optimization
which touched unuse_temporary_mm() in a way incompatible with these patches.

I'll see if I can find time this merge window to also finish that last patch
so that x86 can indeed switch to MMU_LAZY_TLB_REFCOUNT=n, that too should help
with context switch times.
