Subject: vdso/gettimeofday: Rename __arch_get_vdso_u_timens_data()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d453fff35806b1108ae7709de0521bd42770b13;p=thirdparty%2Fkernel%2Flinux.git

vdso/gettimeofday: Rename __arch_get_vdso_u_timens_data()

Originally this function was supposed to work the same way as
__arch_get_vdso_u_time_data() and be overridden on some architectures.
However the actually used implementation, which just adds PAGE_SIZE, does
not need this override mechanism.

Adjust the name to reflect the true nature of the function.
