core: Preserve IF through call16() 2010-06-21T17:03:03+00:00 H. Peter Anvin hpa@zytor.com 2010-06-21T17:03:03+00:00 4e7d836b8cdc0e785ac6e0a78b258c4e193d2222 An intcall should always be invoked with interrupts off, but that is not necessarily the case for a near or far call; in fact it is quite the exception. As such, do not filter IF in our register image, and for our own internal call16() interface, propagate the protected-mode IF value into real mode, just as we do for the pm_call interface.

core: move real-mode callback code to callback.inc 2009-05-17T23:41:10+00:00 H.

Move them to a separate file, and let com32.inc be only the items related to comboot files proper. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
