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); ^
