Subject: powerpc/mm: Move tlbcam_sz() and make it static
X-Git-Tag: v5.17-rc1~84^2~139
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ff47a95d1a67477e9bc2049a840d93b68508e079;p=thirdparty%2Flinux.git

powerpc/mm: Move tlbcam_sz() and make it static

Building with W=1 we see a warning:
  linux/arch/powerpc/mm/nohash/fsl_book3e.c:63:15: error: no previous prototype for ‘tlbcam_sz’

tlbcam_sz() is not used outside this file, so we can make it static.
However it's only used inside #ifdef CONFIG_PPC32, so move it within
that ifdef, otherwise we would get a defined but not used error.
