+Subject: Fix AVX detection
+
+The old/faulty code would try to use AVX/AVX2 if either the SSE bit or
+the AVX bit were set in XCR0, but did not check if both bits were set.
+
+In most cases, this still worked, but on some machines, enabling linux
+kernel mitigations for the "gather data sampling" vulnerability results
+in only the SSE bit but not the AVX bit being set, thus resulting in an
+illegal instruction and crashing the application.
+
+Fix this by checking that both bits are set.
+
+Fixes: 4bbb590 ("Proper check of CPU's AVX2 feature support (with MSVC support)")
