Now that all the work is done to enable the PV backends to work without
actual Xen, instantiate the bus from pc_basic_device_init() for emulated
mode.
This allows us finally to launch an emulated Xen guest with PV disk.

This is only part of it; we will also need to get the PV back end drivers
to tear down their own mappings (or do it for them, but they kind of need
to stop using the pointers too).
Some more work on the actual PV back ends and x

Now that we have an internal implementation of XenStore, we can populate
the xenstore_backend_ops to allow PV backends to talk to it.
Watches can't be processed with immediate callbacks because that would
call back into XenBus c

This is limited to mapping a single grant at a time, because under Xen the
pages are mapped *contiguously* into qemu's address space, and that's very
hard to do when those pages actually come from anonymous mappings in qemu

The following changes were made:
* Make GENERIC_BUG_FRAME mandatory for X86
* Update asm/bug.h using generic implementation in
* Update do_invalid_op using generic do_bug_frame()
* Define BUG_DEBUGGER_TRAP_FATAL to debugger_trap_fatal(X86_EXC_GP,regs)
* type of eip variable was changed to 'void *'
A large part of the content of the bug.h is repeated among all
architectures, so it was decided to create a new config
CONFIG_GENERIC_BUG_FRAME.
The version of from x86 was taken as the base version.
The patch introduces the following stuff:
* common bug.h header
* generic implementation of
The following changes were made:
* make GENERIC_BUG_FRAME mandatory for ARM
* As do_bug_frame() returns -EINVAL in case something goes wrong
otherwise id of bug frame. Thereby 'if' cases where do_bug_frame() was
updated to check if the returned value is less than 0
* Switch ARM's implementation
The idea of the patch is to change all to and
keep Xen compilable with adding only minimal amount of changes:
1. It was added "#include " to ARM's "" as it
uses uint_{16,32}t in 'struct bug_frame'.
2. It was added '#define BUG_FRAME_STRUCT' which means that ARM hasn't
been switched to generic
