Subject: [PATCH v2 0/1] arm/arm64: add support for folded p4d page tables
Date: Mon, 13 Jan 2020 13:13:22 +0200	[thread overview]
Message-ID: <20200113111323.10463-1-rppt@kernel.org> (raw)

From: Mike Rapoport <rppt@linux.ibm.com>

Hi,

This is a part of clean up of the page table manipulation code that aims to
remove asm-generic/5level-fixup.h and asm-generic/pgtable-nop4d-hack.h

There is a single patch for both arm and arm64 because doing the conversion
separately would mean breaking the shared mmu bits in virt/kvm/arm.

v2:
* fix build error for arch/arm64/mm/dump.c
* simplify p4d unfolding in arch/arm64/mm/kasan_init.c
