[PATCH v2 3/4] powerpc/64: make buildable without CONFIG_COMPAT

There are numerous references to 32bit functions in generic and 64bit code so ifdef them out. Signed-off-by: Michal Suchanek --- v2: - fix 32bit ifdef condition in signal.c - simplify the compat ifdef condition in vdso.c - 64bit is redundant - simplify the compat ifdef condition in callchain.c

[PATCH v2 1/4] fs: always build llseek.

64bit !COMPAT does not build because the llseek syscall is in the tables. Signed-off-by: Michal Suchanek --- fs/read_write.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/fs/read_write.c b/fs/read_write.c index 5bbf587f5bc1..9db56931eb26 100644 --- a/fs/read_write.c +++ b/fs/read_write.c
