Subject: [PATCH 0/5] Minor improvements to the compat vdso and sigpage
Date: Thu, 18 Mar 2021 17:07:33 +0000 [thread overview]
Message-ID: <20210318170738.7756-1-will@kernel.org> (raw)
Hi all,
Here are a few small improvements to the compat vDSO and sigpage
implementation for arm64 which I cooked up when comparing the code with
the native 32-bit counterpart.
Cheers,
Will

arm64: vdso: Use GFP_KERNEL for allocating compat vdso and signal
pages
arm64: vdso: Remove redundant calls to flush_dcache_page()
arm64: compat: Allow signal page to be remapped
arm64: vdso: Avoid ISB after reading from cntvct_el0
arm64: compat: Poison the compat sigpage
