Subject: vdso: Remove timekeeper argument of __arch_update_vsyscall()
X-Git-Tag: v6.13-rc1~172^2~41
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=39c089a01a7e431383710a566864644cbbc0f8fe;p=thirdparty%2Fkernel%2Flinux.git

vdso: Remove timekeeper argument of __arch_update_vsyscall()

No implementation of this hook uses the passed in timekeeper anymore.

This avoids including a non-VDSO header while building the VDSO, which can
lead to compilation errors.
