This patch triggers:

Building loongarch:defconfig ... failed
--------------
Error log:
arch/loongarch/kernel/vdso.c: In function 'vvar_fault':
arch/loongarch/kernel/vdso.c:54:36: error: implicit declaration of function 'find_timens_vvar_page'

because the missing function is not generic in v6.1.y.

Reverting the patch on its own does not work because commit a67d4a02bf43
("LoongArch: Don't crash in stack_top() for tasks without vDSO") depends on it.
Reverting both patches fixes the problem.

Copying the authors of both patches for advice.
