These commits allow identifying the microcode level [MCL] of a [Z] system, hence let's one [IBM] know if the level includes mitigation for Spectre or not. Both commits are in mailine as of v4.12-rc1. == Fixes == 09214545c4a4 ("s390/bitops: add for_each_set_bit_inv helper") 157467ba9fb7 ("s390/cpuinfo: show facilities as reported by stfle") == Regression Potential == Low. These fixes are specific to s390. == Original Bug Description == Please backport this upstream commit: commit 157467ba9fb7e379f0540707dd89111de441e45e Author: Heiko Carstens <[email protected]> Date: Sat Feb 25 12:16:48 2017 +0100 s390/cpuinfo: show facilities as reported by stfle Add a new line to /proc/cpuinfo which shows all available facilities as reported by the stfle instruction: > cat /proc/cpuinfo ... facilities : 0 1 2 3 4 6 7 ... ... As pre-req, also apply commit 9194bc62e6314f4d8cef60e80070ca2bb4182e99 Author: Heiko Carstens <[email protected]> Date: Sat Feb 25 12:16:31 2017 +0100 s390/bitops: add for_each_set_bit_inv helper Same helper function like for_each_set_bit in generic code. which introduces for_each_set_bit_inv() that is used to process the facilities bits.
