Date: Sun, 07 Oct 2012 00:20:16 +0000 [thread overview]
Message-ID: <20121007002016.GA5678@localhost> (raw)
Hi Cyrill,
FYI, there are new compile warnings show up in
commit: 20e61e149ba9a4fe4c4867a76e399879d802e669 prctl: use access_ok() instead of TASK_SIZE in prctl_set_mm()
config: m68k-allmodconfig
All warnings:
kernel/sys.c: In function 'prctl_set_mm':
kernel/sys.c:1868:2: warning: passing argument 2 of 'access_ok' makes pointer from integer without a cast [enabled by default]
arch/m68k/include/asm/uaccess_mm.h:17:19: note: expected 'const void *' but argument is of type 'long unsigned int'
