linux-next: build failure after merge of the tiny tree

Hi Josh,

After merging the tiny tree, today's linux-next build (powerpc64 allnoconfig)
failed like this:

arch/powerpc/kernel/built-in.o: In function `sys_call_table':
(.rodata+0xd58): undefined reference to `.compat_sys_adjtimex'
arch/powerpc/kernel/built-in.o: In function `sys_call_table':
(.rodata+0x1b48): undefined reference to `.compat_sys_clock_adjtime'

Caused by commit be1e48a8e48f ("kernel: time: Compile out NTP support").

I have reverted that commit for today.

Good catch, thanks.  Not clear why that build failure didn't show up on
x86.

Looks like the two compat syscalls need cond_syscall lines as well.
I'll add those to the patch.

Done in current tiny/next.

Strange.  That commit compiled just fine here with several
configurations; I'll investigate what's up with ppc64_defconfig.
Will revert for now.

Hi Josh,

After merging the tiny tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit b37a3fee8450 ("mm: Disable mm/balloon_compaction.c
completely when !CONFIG_VIRTIO_BALLOON").

I have reverted that commit for today.
