/*
* Initializing the BIOS on a video card on a bus without
* a south bridge (subtractive decode agent) can result in
* master aborts as the BIOS probes the capabilities of the
* card. XFree86 does such initialization. If the error
* is a master abort (No DevSel as PCI Master) and the command
* is an I/O read or write below the address where we start
* assigning PCI I/O spaces (SRM uses 0x1000), then mark the
* error as dismissable so starting XFree86 doesn't result
* in a series of uncorrectable errors being reported. Also
* dismiss master aborts to VGA frame buffer space
* (0xA0000 - 0xC0000) and legacy BIOS space (0xC0000 - 0x100000)
* for the same reason.
*
* Also mark the error dismissible if it looks like the right
* error but only the Lost bit is set. Since the BIOS initialization
* can cause multiple master aborts and the error interrupt can
* be handled on a different CPU than the BIOS code is run on,
* it is possible for a second master abort to occur between the
* time the PALcode reads PERROR and the time it writes PERROR
* to acknowledge the error. If this timing happens, a second
* error will be signalled after the first, and if no additional
* errors occur, will look like a Lost error with no additional
