Subject: linux-next: build failure after merge of the akpm tree
Date: Tue, 2 Jun 2020 19:57:41 +1000 [thread overview]
Message-ID: <20200602195741.4faaa348@canb.auug.org.au> (raw)

Hi all,
After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
ERROR: modpost: ".probe_user_write" [arch/powerpc/kvm/kvm-hv.ko] undefined!
Caused by patch
"maccess: unexport probe_kernel_write and probe_user_write"
"These two functions are not used by any modular code." turns out to
not be true :-(
I have added this patch:
