Subject: [PATCH v3 03/14] hexagon: remove __ARCH_USE_5LEVEL_HACK
Date: Thu, 27 Feb 2020 08:45:57 +0000 [thread overview]
Message-ID: <20200227084608.18223-4-rppt@kernel.org> (raw)
In-Reply-To: <20200227084608.18223-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The hexagon architecture has 2 level page tables and as such most of the
page table folding is already implemented in asm-generic/pgtable-nopmd.h.
Fixup the only place in arch/hexagon to unfold the p4d level and remove
__ARCH_USE_5LEVEL_HACK.

Subject: [PATCH v3 03/14] hexagon: remove __ARCH_USE_5LEVEL_HACK
Date: Thu, 27 Feb 2020 10:45:57 +0200 [thread overview]
Message-ID: <20200227084608.18223-4-rppt@kernel.org> (raw)
In-Reply-To: <20200227084608.18223-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The hexagon architecture has 2 level page tables and as such most of the
page table folding is already implemented in asm-generic/pgtable-nopmd.h.
Fixup the only place in arch/hexagon to unfold the p4d level and remove
__ARCH_USE_5LEVEL_HACK.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
