Subject: [PATCH 0/3] x86/mm/encrypt: Simplify pgtable helpers
Date: Tue, 12 Dec 2017 14:45:41 +0300 [thread overview]
Message-ID: <20171212114544.56680-1-kirill.shutemov@linux.intel.com> (raw)
This patchset simplifies sme_populate_pgd(), sme_populate_pgd_large() and
sme_pgtable_calc() functions.
As a side effect, the patchset makes encryption code ready to boot-time
switching between paging modes.
The patchset is build on top of Tom's "x86: SME: BSP/SME microcode update
fix" patchset.
It was only build-tested. Tom, could you please get it tested properly?
