From: Sandipan Das Date: Mon, 25 Mar 2024 07:31:44 +0000 (+0530) Subject: x86/cpufeatures: Add new word for scattered features X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=571d80f8a4581ba48fd3dc834e91139ec95abe52;p=users%2Fdwmw2%2Flinux.git x86/cpufeatures: Add new word for scattered features commit 7f274e609f3d5f45c22b1dd59053f6764458b492 upstream. Add a new word for scattered features because all free bits among the existing Linux-defined auxiliary flags have been exhausted.
