Subject: [RESEND PATCH 0/4] Rework sparc32 page-table layout
Date: Tue, 14 Apr 2020 22:40:07 +0100 [thread overview]
Message-ID: <20200414214011.2699-1-will@kernel.org> (raw)
Hi all,
This is a reposting of the patch series I sent previously to rework the
sparc32 page-table layout so that 'pmd_t' can be used safely with
READ_ONCE():
https://lore.kernel.org/lkml/20200324104005.11279-1-will@kernel.org
This is blocking the READ_ONCE() rework, which in turn allows us to
bump the minimum GCC version for building the kernel up to 4.8.
Cheers,
Will
