4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Lamparter <chunkeey@xxxxxxxxx>
commit d0757237d7b18b1ce74293be7c077d86f7a732e8 upstream.
This patch fixes a recent compilation regression in ocm:
ocm.c: In function ‘ocm_init_node’:
ocm.c:182:18: error: invalid operands to binary |
(have ‘int’ and ‘pgprot_t’ {aka ‘struct <anonymous>’})
_PAGE_EXEC | PAGE_KERNEL_NCG);
^
ocm.c:197:17: error: invalid operands to binary |
(have ‘int’ and ‘pgprot_t’ {aka ‘struct <anonymous>’})
_PAGE_EXEC | PAGE_KERNEL);
^
Fixes: 56f3c1413f5c ("powerpc/mm: properly set PAGE_KERNEL flags in ioremap()")
