Subject: [ARM] kmap: fix build errors with DEBUG_HIGHMEM enabled
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4ff1fa278b0bd1b2dd3c42efc0cb86788ffe05d5;p=openwrt%2Fstaging%2Fblogic.git

[ARM] kmap: fix build errors with DEBUG_HIGHMEM enabled

d451564 broke ARM by requiring KM_IRQ_PTE, KM_NMI and KM_NMI_PTE to
always be defined.  Solve this by providing invalid definitions for
these constants, but only if CONFIG_DEBUG_HIGHMEM is enabled.
