Subject: MIPS: lib: strnlen_user: Use macro to build the strnlen_user symbol
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c48be43eb5248ff96dacda58f9e51ee8bfd058ac;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

MIPS: lib: strnlen_user: Use macro to build the strnlen_user symbol

Build the __strnlen_user symbol using a macro. In EVA mode we will
need to use similar code to do the userspace load operations so
it is better if we use a macro to avoid code duplications.
