This is the start of the stable review cycle for the 4.4.213 release. There are 53 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.
Responses should be made by Wed, 05 Feb 2020 16:17:59 +0000. Anything received after that time might be too late.
We're seeing an issue with 4.4.213-rc1 (36670370c48b) and 4.4.213-rc2 (758a39807529) with our 4 am335x configurations [0]:
AS arch/arm/kernel/hyp-stub.o arch/arm/kernel/hyp-stub.S: CC arch/arm/mach-omap2/sram.o Assembler messages: AS arch/arm/kernel/smccc-call.o arch/arm/kernel/hyp-stub.S:147: Error: selected processor does not support `ubfx r7,r7,#16,#4' in ARM mode scripts/Makefile.build:375: recipe for target 'arch/arm/kernel/hyp-stub.o' failed make[1]: *** [arch/arm/kernel/hyp-stub.o] Error 1
The culprit seems to be: 15163bcee7b5 ("ARM: 8955/1: virt: Relax arch timer version check during early boot") Reverting the same resolves the build issue.

Thanks, I'll go drop that patch from 4.4 and 4.9 trees.
I believe it is more likely than not to break 4.19 (and possibly mainline), too, but I have not yet done required testing.
Best regards, Pavel
