Subject: [PATCH] i386/cpu: Clear FEAT_XSAVE_XSS_LO/HI leafs when
|
|
CPUID_EXT_XSAVE is not available
|
|
|
|
commit 81f5cad3858f27623b1b14467926032d229b76cc upstream.
|
|
|
|
Leaf FEAT_XSAVE_XSS_LO and FEAT_XSAVE_XSS_HI also need to be cleared
|
|
when CPUID_EXT_XSAVE is not set.
|
|
|
|
Fixes: 301e90675c3f ("target/i386: Enable support for XSAVES based features")
