Subject: [PATCH 0/2] Allow nesting of lazy MMU mode
Date: Thu, 12 Oct 2023 20:54:13 +0100 [thread overview]
Message-ID: <20231012195415.282357-1-willy@infradead.org> (raw)
Dave Woodhouse reported that we now nest calls to
arch_enter_lazy_mmu_mode(). That was inadvertent, but in principle we
should allow it. On further investigation, Juergen already fixed it
for Xen, but didn't tell anyone. Fix it for Sparc & PowerPC too.
This may or may not help fix the problem that Erhard reported.
