[ Upstream commit 706d51681d636a0c4a5ef53395ec3b803e45ed4d ]

Changes from upstream:

1. Use bit 30 of word 7 in cpufeatures for X86_FEATURE_IBRS_ENHANCED as bit 29 is now used by L1TF.
2. Fix some trivial line fuzzing.

Based on kernel version:

Linux 4.9.135

This format is very odd, shouldn't it go all below the original --- line?

Please fix up and resend properly. Also, why 4.9? What is wrong with 4.18.y, 4.14.y, and 4.4.y? Just picking one random kernel in the middle of the stable releases seems foolish for those users of newer kernels, right?

thanks,
