4.4-stable review patch. If anyone has any objections, please let me know.
fyi, I bisected a regression down to this commit. This apparently causes an ADR_PREL_PG_HI21 relocation to be added to the sha{1,2}_ce modules. Back in 4.4 ADR_PREL_PG_HI21 relocations were forbidden if built with CONFIG_ARM64_ERRATUM_843419=y, so now the sha{1,2}_ce modules fail to load:
[ 37.866250] module sha1_ce: unsupported RELA relocation: 275
Looks like it should be an issue for 4.14.y as well, but I haven't yet tested it.
This regression appears to be limited to 4.4.y. I didn't find it when testing 4.9.y, and a 2nd bisection determined that it is because 4.9.y+ also contains a backport of commit 41c066f ("arm64: assembler: make adr_l work in modules under KASLR"). That was pulled from 4.4.y because it caused a build failure:

Shall I submit a revert of this patch for 4.4.y, or is it worth trying to get a backport of 41c066f to work?
Which ever you think would be best is fine.
