similar to: [PATCH] change BUILD_BUG_ON()

The SeaBIOS ROM image may validly exceed 128k in size, it''s only our interface code that so far assumed that it wouldn''t. Remove that restriction by setting the base address depending on image size. Add a check to HVM loader so that too big images won''t result in silent guest failure anymore. Uncomment the intended build-time size check for rombios, moving it into a

Hello, The email (thread) below from xen-devel mailinglist indicates the changesets that should fix the bug that causes the lenny 2.6.26 xen kernel to crash on newer xen hypervisors. The workaround for this bug has been to use pci=nomsi on the dom0 kernel cmdline, but it would be better to apply the actual fix to the xen kernel in lenny. More information on xen-devel (archives). -- Pasi

Commit 111e7b15cf10f6 ("x86/ioperm: Extend IOPL config to control ioperm() as well") reworked the iopl syscall to use I/O bitmaps. Unfortunately this broke Xen PV domains using that syscall as there is currently no I/O bitmap support in PV domains. Add I/O bitmap support via a new paravirt function update_io_bitmap which Xen PV domains can use to update their I/O bitmaps via a
