Date: Mon, 11 Mar 2019 15:55:03 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Guo Ren <ren_guo@...ky.com>, Sasha Levin <sashal@...nel.org> Subject: [PATCH AUTOSEL 4.20 39/52] csky: Fixup _PAGE_GLOBAL bit for 610 tlb entry From: Guo Ren <ren_guo@...ky.com> [ Upstream commit 62eebea655d4be5a20fd563abfd7656724cdcd00 ] C-SKY CPU 8xx's _PAGE_GLOBAL is BIT(0), but 610's _PAGE_GLOBAL is BIT(6). Use _PAGE_GLOBAL macro instead of bad magic number.
