Keir Fraser 796b445b00 minios: call do_hypervisor_callback directly from force_evtchn_callback 
instead of unnecessarily going through the hypervisor.

Keir Fraser 28baa78877 stubdom: sparse application's BSS by linking it separately first, put 
markers at its beginning and end, and then link with mini-os.
That permits to stick a bit more to upstream qemu.

Keir Fraser f464d312c7 x86: Fix emulation of PCI access register at I/O port 0xcf8. 
The register is only visible for DWORD accesses. Furthermore, some
chipsets place other registers in the range 0xf8-0xcfb for sub-DWORD
accesses.

Keir Fraser d354d1ec94 [IA64] Fix pci.h include overlap 
The new upstream xen/pci.h has a name conflict with our modified
linux/pci.h and shows up earlier in the include search path.  Since
our usage of linux/pci.h is limited, rename to linux/linux-pci.h to
avoid duplicate names and cleanup the few users.

Keir Fraser a29af79e4e Change tasklet implementation so that tasklet_kill() does not have to 
busy-wait for softirq work to start. This reduces the possibility of
deadlocks, but the implementation is now less efficient. For the
current few users of tasklets this does not matter.

Keir Fraser fd1527b4d2 x86/64 compat: Replace hypervisor BUG_ON() with a cleaner hypercall failure. 
While trying to run a 32-bit PV domU on a 64-bit hypervisor, I
triggered an assert in the hypervisor.  The assert dealt with the
maximum number of grants that a domU can have.  I made the hypervisor
a bit more graceful by returning an error rather than asserting.
