Subject: highmem: Export totalhigh_pages.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db7a94d60f871ce6a52e97d82dea476cee0c4ea0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

highmem: Export totalhigh_pages.

Hash et al. sizing code in SCTP wants to make the
calculation totalram_pages - totalhigh_pages, just
like TCP.  But this requires an export for the
CONFIG_HIGHMEM case to work.
