Subject: [PATCH v3 0/2] Clear .bss for VP guests
Date: Thu, 25 Feb 2016 10:16:33 -0500 [thread overview]
Message-ID: <1456413395-7679-1-git-send-email-boris.ostrovsky@oracle.com> (raw)
PV guests need to have their .bss zeroed out since it is not guaranteed
to be cleared by Xen's domain builder
v3:
* Use existing macros for selecting mode-appropriate instructions/registers
* Use 32-bit registers in XOR
* Split removal of mode-selecting ifdefs into a separate patch

xen/x86: Drop mode-selecting ifdefs in startup_xen()
