target-mips: fix user-mode emulation startup
Running programs with the MIPS user-mode emulator fails during dynamic
loading, as floating-point instructions are not enabled in in
env->hflags. Move the code for doing so from fpu_init to cpu_reset so
the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset
setting env->hflags to MIPS_HFLAG_UM.
The same end can be achieved by swapping the ordering of fpu_init and
cpu_reset in cpu_mips_init, but it seemed better to consolidate the

keysyms for letters to lowercase for the keysym2scancode lookup. It
then also passes the lowercase value down to do_key_event(), but the

This patch adds a new variable for the lowercase keysym so we'll keep

scsi: fix drive hotplug.
This patch fills the DriveInfo->unit after hotplugging a scsi disk.
It makes a difference when auto-assigning a scsi id, where unit was
left filled with '-1' instead of the actual scsi id.
With this patch applied the the drive naming logic in drive_init() works
as good as it did in previous releases. Which means it works fine with
a single scsi bus.

pci: don't hw_error() when no slot is available.
Current PCI code will simply hw_error() and thus abort in case no free
PCI slot is available or the requested PCI slot is already in use by
another device. For the hotplug case this behavior is not acceptable.
This patch makes qemu pass up the error properly, so the calling code
can decide whenever it wants to exit with an error (on startup) or
whenever it wants to continue (hotplug).

pci: don't abort() when trying to hotplug with acpi off.
The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI
also disables hotplug for the PCI bus. This patch makes qemu check
whenever the PCI bus in question can handle hotplug before trying to add
devices. This is needed because qdev will abort() on any attempt to
