Subject: [patch 113/200] arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
Date: Mon, 14 Dec 2020 19:09:55 -0800	[thread overview]
Message-ID: <20201215030955.RzGlA2IWP%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201214190237.a17b70ae14f129e2dca3d204@linux-foundation.org>

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL

ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence  of struct page associated with a pfn when there are holes
in the memory map.

However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.

The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.

Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.
