[PATCH v3 18/19] arch/sparc: Implement with generic helpers

Thomas Zimmermann
2023-04-17T12:59:02Z

Replace sparc64's fb_pgprotect() with the generic one
from <asm-generic/fb.h>. On sparc, pgprot_writecombine() and
pgprot_noncached() are the same; hence no functional changes

v3:
* use default implementation for fb_pgprotect() on
sparc64 (Arnd)
v2:
* restore the original fb_pgprotect()
