X-Git-Tag: microblaze-v5.13~334^2~2
X-Git-Url: http://git.monstr.eu/?p=linux-2.6-microblaze.git;a=commitdiff_plain;h=adc5d8757288a3a5628436d16e78fb696d802e39

signal: Add missing __user annotation to copy_siginfo_from_user_any

copy_siginfo_from_user_any() takes a userspace pointer as second
argument; annotate the parameter type accordingly.
