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

Hi all,

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

drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c: In function 'bnxt_ptp_init':
drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:1141:13: error: implicit declaration of function 'boot_cpu_has'; did you mean 'boot_cpu_init'? [-Wimplicit-function-declaration]

      |             ^~~~~~~~~~~~

 1141 |             boot_cpu_has(X86_FEATURE_ART))
      |                          ^~~~~~~~~~~~~~~

drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:1141:26: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  c470195b989f ("bnxt_en: Add PTP .getcrosststamp() interface to get device/host times")

boot_cpu_has() only exists for X86 ...

I have applied the folloring hack for today:
