Hi all,

After the following patch, we are unable to build the 4.14 tree with EL6 -=
=20
which uses gcc 4.4.7

The failure logs are as follows:
BUILDSTDERR: arch/x86/kernel/head64.c: In function 'copy_bootdata':
BUILDSTDERR: ./arch/x86/include/asm/mem_encrypt.h:59: sorry, unimplemented:=
=20
inlining failed in call to 'sme_map_bootdata': function not inlinable
BUILDSTDERR: arch/x86/kernel/head64.c:294: sorry, unimplemented: called fro=
m=20
here
BUILDSTDERR: ./arch/x86/include/asm/mem_encrypt.h:60: sorry, unimplemented:=
=20
inlining failed in call to 'sme_unmap_bootdata': function not inlinable
BUILDSTDERR: arch/x86/kernel/head64.c:310: sorry, unimplemented: called fro=
m=20
here

Patch in question:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/
commit/arch/x86/include/asm/mem_encrypt.h?
h=3Dlinux-4.14.y&id=3De0f82cbde41353ddf63935175583ceb5580cce87

I can confirm that this builds fine with EL7.
