Subject: linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

arch/arm/kernel/vdso.c: In function 'tk_is_cntvct':
arch/arm/kernel/vdso.c:273:15: error: 'const struct timekeeper' has no member named 'tkr'
  if (strcmp(tk->tkr.clock->name, "arch_sys_counter") != 0)
               ^
arch/arm/kernel/vdso.c: In function 'update_vsyscall':
arch/arm/kernel/vdso.c:319:32: error: 'struct timekeeper' has no member named 'tkr'
   vdso_data->cs_cycle_last = tk->tkr.cycle_last;
                                ^
arch/arm/kernel/vdso.c:321:36: error: 'struct timekeeper' has no member named 'tkr'
   vdso_data->xtime_clock_snsec = tk->tkr.xtime_nsec;
                                    ^
arch/arm/kernel/vdso.c:322:27: error: 'struct timekeeper' has no member named 'tkr'
   vdso_data->cs_mult  = tk->tkr.mult;
                           ^
arch/arm/kernel/vdso.c:323:28: error: 'struct timekeeper' has no member named 'tkr'
   vdso_data->cs_shift  = tk->tkr.shift;
                            ^
arch/arm/kernel/vdso.c:324:27: error: 'struct timekeeper' has no member named 'tkr'
   vdso_data->cs_mask  = tk->tkr.mask;
                           ^

Caused by commit 876e78818def ("time: Rename timekeeper::tkr to
timekeeper::tkr_mono") from the tip tree interacting with commit
ecf99a439105 ("ARM: 8331/1: VDSO initialization, mapping, and
synchronization") from the arm tree.

I added this merge fix patch for today (is that all that is needed?):
