Hi all,
After merging the vfs tree, today's linux-next build (sparc_defconfig)
failed like this:
arch/sparc/lib/memset.S: Assembler messages:
arch/sparc/lib/memset.S:149: Error: Unknown opcode: `ext(12b, 13b,21f)'
Caused by commit
0e0bbae08a6e ("sparc32: switch __bzero() away from range exception table entries")
merging badly with commit
7780918b3648 ("sparc32: fix a user-triggerable oops in clear_user()")
from the sparc tree.
The sparc tree commit above appears as commit
80537bbf19d6 ("sparc32: fix a user-triggerable oops in clear_user()")
in the vfs tree as well. The patch adds one line which is later removed
by commit
0e0bbae08a6e ("sparc32: switch __bzero() away from range exception table entries")
in the vfs tree, but the git merge puts the line back again :-(
I have added the following fix to the vfs tree merge
