Subject: [PATCH] i386/cpu: Mask with XCR0/XSS mask for FEAT_XSAVE_XCR0_HI and
|
|
FEAT_XSAVE_XSS_HI leafs
|
|
|
|
commit a11a365159b944e05be76f3ec3b98c8b38cb70fd upstream.
|
|
|
|
The value of FEAT_XSAVE_XCR0_HI leaf and FEAT_XSAVE_XSS_HI leaf also
|
|
need to be masked by XCR0 and XSS mask respectively, to make it
|
|
logically correct.
