From adc235aff6fcf5ae4d8dc00faf30a07632b9725b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 16 Nov 2015 17:32:15 +0100 Subject: [PATCH] arm64: do not include ptrace.h from compat.h including ptrace.h brings a definition of BITS_PER_PAGE into device drivers and cause a build warning in allmodconfig builds: drivers/block/drbd/drbd_bitmap.c:482:0: warning: "BITS_PER_PAGE" redefined #define BITS_PER_PAGE (1UL << (PAGE_SHIFT + 3)) This uses a slightly different way to express current_pt_regs() that avoids the use of the header and gets away with the already included asm/ptrace.h.
