Subject: [PATCH] get_tss_base_addr() should return gpa_t type.
Date: Sun, 25 Oct 2009 17:42:02 +0200 [thread overview]
Message-ID: <20091025154202.GY29477@redhat.com> (raw)
If TSS we are switching to resides in high memory task switch will fail
since address will be truncated. Windows2k3 does this sometimes when
running with more then 4G
