Subject[PATCH] s390: Add missing PAGE_SHARED as an alias for PAGE_RW
Date
s390 allmodconfig:

drivers/gpu/drm/udl/udl_fb.c:237:52: error: 'PAGE_SHARED' undeclared (first use in this function)
drivers/media/pci/zoran/zoran_driver.c:2955:14: error: 'PAGE_SHARED' undeclared (first use in this function)

drivers/video/vfb.c:431:52: error: 'PAGE_SHARED' undeclared (first use in this function)

According to an email from Martin a few years ago, the equivalent define
for s390 is PAGE_RW, so make PAGE_SHARED an alias for PAGE_RW.
