Subject: [PATCH v2 0/2] x86: Secure Memory Encryption (SME) fixes 2017-07-26
Date: Fri, 28 Jul 2017 11:01:15 -0500 [thread overview]
Message-ID: <cover.1501186516.git.thomas.lendacky@amd.com> (raw)
This patch series addresses some issues found during further testing of
Secure Memory Encryption (SME).
The following fixes are included in this update series:
- Fix a cache-related memory corruption when kexec is invoked in
successive instances
- Remove the encryption mask from the protection properties returned
by arch_apei_get_mem_attribute() when SME is active
---
This patch series is based off of the master branch of tip:
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git master
Commit 8333bcad393c ("Merge branch 'x86/asm'")
Cc: <kexec@lists.infradead.org>
Changes since v1:
- Patch #1:
- Only issue wbinvd if SME is active
- Patch #2:
- Create a no encryption version of the PAGE_KERNEL protection type
and use that in arch_apei_get_mem_attribute()
- General comment and patch description clean up
