Subject: [PATCH 16/21] staging/zsmalloc: don't use pgtable-mapping from modules
Date: Tue, 23 Apr 2013 18:30:48 +0200 [thread overview]
Message-ID: <1366734653-488286-17-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1366734653-488286-1-git-send-email-arnd@arndb.de>
Building zsmalloc as a module does not work on ARM because it uses
an interface that is not exported:
ERROR: "flush_tlb_kernel_range" [drivers/staging/zsmalloc/zsmalloc.ko] undefined!
Since this is only used as a performance optimization and only on ARM,
we can avoid the problem simply by not using that optimization when
building zsmalloc it is a loadable module.
flush_tlb_kernel_range is often an inline function, but out of the
architectures that use an extern function, only powerpc exports
it.
