[PATCH] parisc: fix compilation errrors

From: Qian Cai
Date: Thu Aug 15 2019 - 16:53:36 EST


The commit 0cfaee2af3a0 ("include/asm-generic/5level-fixup.h: fix
variable 'p4d' set but not used") converted a few functions from macros
to static inline, which causes parisc to complain,

In file included from ./include/asm-generic/4level-fixup.h:38:0,
from ./arch/parisc/include/asm/pgtable.h:5,
from ./arch/parisc/include/asm/io.h:6,
from ./include/linux/io.h:13,
from sound/core/memory.c:9:
./include/asm-generic/5level-fixup.h:14:18: error: unknown type name
'pgd_t'; did you mean 'pid_t'?
#define p4d_t pgd_t
^
./include/asm-generic/5level-fixup.h:24:28: note: in expansion of macro
'p4d_t'
static inline int p4d_none(p4d_t p4d)
^~~~~

It is because "4level-fixup.h" is included before "asm/page.h" where
"pgd_t" is defined.
