From: Zenghui Yu <yuzenghui@huawei.com> mainline inclusion from mainline-v6.2-rc4 commit eb9a85261e297292c4cc44b628c1373c996cedc2 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8E73O CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... ------------------------------------------------- We currently guard REGSET_{SSVE, ZA} using ARM64_SVE for no good reason. Both enumerations would be pointless without ARM64_SME and create two empty entries in aarch64_regsets[] which would then become part of a process's native regset view (they should be ignored though). Switch to use ARM64_SME instead.
