Subject: ia64: remove 'ifdef CONFIG_ZONE_DMA32' statements
X-Git-Tag: v5.15~2223^2~92
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5d37fc0b087fb276a257034c5a1dfdbfaa08be66;p=platform%2Fkernel%2Flinux-starfive.git

ia64: remove 'ifdef CONFIG_ZONE_DMA32' statements

After the removal of SN2 platform (commit cf07cb1ff4ea ("ia64: remove
support for the SGI SN2 platform") IA-64 always has ZONE_DMA32 and there is
no point to guard code with this configuration option.

Remove ifdefery associated with CONFIG_ZONE_DMA32
