Subject: [GIT PULL] x86/sgx for 6.2
Date: Mon, 12 Dec 2022 11:15:25 -0800 [thread overview]
Message-ID: <20221212191525.553277-1-dave.hansen@linux.intel.com> (raw)
Hi Linus,
Please pull some x86/sgx changes for v6.2.
The biggest deal in this series is support for a new hardware feature
that allows enclaves to detect and mitigate single-stepping attacks.
There's also a minor performance tweak and a little piece of the
kmap_atomic()=>kmap_local() transition.
