Paolo Bonzini 7447545544 change all other clock references to use nanosecond resolution accessors
This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

Isaku Yamahata b80d4a9887 pci: don't overwrite multi functio bit in pci header type.
Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared.

how to test:
run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

Aurelien Jarno 409dbce54b load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.

This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.

The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

- added missing timer debug output macro
- CPUTimer struct and typedef moved to cpu.h
- change CPU_SAVE_VERSION to 6, older save formats not supported

v1 -> v2:

- renamed struct sun4u_timer to CPUTimer
- load and save cpu timers

Gerd Hoffmann 3c178e72e0 rom loader: fix sparc -kernel boot.
Changes:
(1) register pstrcpy_targphys() in rom list, it is used for kernel
command lines by a number of architectures.
(2) add rom_ptr() function to get a pointer for applying changes
to loaded images.  Needed for example to tell the linux kernel
where it finds the initrd image by updating the header.
(3) make sparc use rom_ptr for initrd setup.

booting sparc-test works now, and 'info roms' shows this:

(qemu) info roms
addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx"

Markus Armbruster e23a1b33b5 New qdev_init_nofail()
Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.

Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling.  I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

Markus Armbruster 07caea315a Fix pci_add nic not to exit on bad model
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC.  When MODEL is unknown or "?", this prints to stderr
and terminates the program.

Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure.  Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.

Bonus bug fix: we now check for qdev_init() failing there.

Gerd Hoffmann 81a322d4a1 qdev: add return value to init() callbacks.
Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.
