[PATCH 04/26] mm/vmalloc: Add empty <asm/vmalloc.h> headers and use them from <linux/vmalloc.h>

19 Oct 2020

From: Ingo Molnar mingo@kernel.org
mainline inclusion
from mainline v5.6-rc1
commit 1f059dfdf5d170dccbac92193be2fee3c1763384
category: feature
bugzilla: NA
CVE: NA
---------------------------
In the x86 MM code we'd like to untangle various types of historic
header dependency spaghetti, but for this we'd need to pass to
the generic vmalloc code various vmalloc related defines that
customarily come via the <asm/page.h> low level arch header.
