Subject: [PATCH AUTOSEL 4.14 09/13] parisc: Use absolute_pointer() to define PAGE0

From: Helge Deller <deller@....de>

[ Upstream commit 90cc7bed1ed19f869ae7221a6b41887fe762a6a3 ]

Use absolute_pointer() wrapper for PAGE0 to avoid this compiler warning:

  arch/parisc/kernel/setup.c: In function 'start_parisc':
  error: '__builtin_memcmp_eq' specified bound 8 exceeds source size 0
