d5b406d95b ATA: Allow WIN_SECURITY_FREEZE_LOCK as nop
When using Windows 8 with an AHCI disk drive, it issues a blue screen.
The reason is that WIN_SECURITY_FREEZE_LOCK / CFA_WEAR_LEVEL is not
supported by our ATA implementation, but Windows expects it to be there.

Since without security stuff implemented, the lock would be a nop anyway
and CFA_WEAR_LEVEL already is treated as a nop, let's just allow the cmd
for HD drives as well. That way Windows is happy.

787f31330e rbd: add discard support
Change the write flag to an operation type in RBDAIOCB, and make the
buffer optional since discard doesn't use it.

Discard is first included in librbd 0.1.2 (which is in Ceph 0.46).
If librbd is too old, leave out qemu_rbd_aio_discard entirely,
so the old behavior is preserved.

276eda5735 Declare state directory in smb.conf
The smb.conf generated by the userspace networking does not include a state directory
directive. Samba therefore falls back to the default value. Since the user generally
does not have write access to this path, smbd immediately crashes.

The "state directory" option was added in Samba 3.4.0 (commit
http://gitweb.samba.org/?p=samba.git;a=commit;h=7b02e05eb64f3ffd7aa1cf027d10a7343c0da757).

This patch adds the missing option.

de305b1387 slirp: don't use "smb ports = 0" option
The "smb ports = 0" option causes recent samba versions to crash. It was
introduced in commit 157777ef3e with log message "Samba 3 support".
However, a value of 0 has never been officially supported by smb and is
also not necessary: if stdin is a socket, smb does not try to listen on
any ports and uses just stdin. This is necessary to support inetd based
operation (otherwise smbd would always fail when called from inetd,
because inetd already listens on the SMB port). Since samba has
supported inetd operation since pre-3.x, it should be safe to rely on
this feature. I have tested it with Samba 3.6.4 -- communication works
fine, and smbd is not listening on any ports.

I suspect the "smb ports = 0" hack may have been introduced when someone
tested the qemu generated samba config from the command line with "smbd
-i" and found it to fail (because then stdin isn't a socket).

ddf1ddcf65 linux-user: Fix invalid TARGET_ABI_BITS usage on ppc hosts
When trying to evaluate the size of the _host_ type size for olddev_t,
we need to expose the host's pointer size, not the guest pointer size.

This usage got introduced accidently in commit b754e4fc1.

Fix things by not using TARGET_.*, but rather use host sizeof()

5f2c23e61a ppce500_spin: Replace assert by hw_error (fixes compiler warning)
The default case in function spin_read should never be reached,
therefore the old code used assert(0) to abort QEMU.

This does not work when QEMU is compiled with macro NDEBUG defined.
In this case (and also when the compiler does not know that assert
never returns), there is a compiler warning because of the missing
return value.

Using hw_error allows an improved error message and aborts always.

Commit ed120055c7 (Implement PAPR VPA

7fb0bd3473 pseries: Use the same interrupt swizzling for host bridges as p2p bridges
Currently the pseries PCI code uses a somewhat strange scheme of PCI irq
allocation - one per slot up to a maximum that's greater than the usual 4.
This scheme more or less worked, because we were able to tell the guest the
irq mapping in the device tree, however it's a bit odd and may break
assumptions in the future.  Worse, the array used to construct the dev
tree interrupt map was mis-sized, we got away with it only because it
happened that our SPAPR_PCI_NUM_LSI value was greater than 7.

This patch changes the pseries PCI code to use the same interrupt swizzling
scheme as is standardized for PCI to PCI bridges.  This makes for better
consistency, deals better with any devices which use multiple interrupt
pins and will make life easier in the future when we add passthrough of
what may be either a host bridge or a PCI to PCI bridge.  This won't break
existing guests, because they don't assume a particular mapping scheme for
host bridges, but just follow what we tell them in the device tree (also
updated to match, of course).  This patch also fixes the allocation of the
irq map.

d601fac478 pseries: Implement automatic PAPR VIO address allocation
PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary,
"address" used as a token to the hypercalls which manipulate them.

Currently the pseries machine code does an ok job of allocating these
addresses when the legacy -net nic / -serial and so forth options are used
but will fail to allocate them properly when using -device.

Specifically, you can use -device if all addresses are explicitly assigned.
Without explicit assignment, only one VIO device of each type (network,
console, SCSI) will be assigned properly, any further ones will attempt
to take the same address leading to a fatal error.

This patch fixes the situation by adding a proper address allocator to the
VIO "bus" code.  This is used both by -device and the legacy options and
default devices.  Addresses can still be explicitly assigned with -device
options if desired.

This patch changes the (guest visible) numbering of VIO devices, but since
their addresses are discovered using the device tree and already differ
from the numbering found on existing PowerVM systems, this does not break
compatibility.

1b296044b6 vga: Don't switch to 1 x 1 character text screen
Initially, vga_get_text_resolution returns a text resolution of 1 x 1
(vga register values are 0).

This is visible during MIPS Malta boot with SDL. It also occurs with the
i386 or x86_64 system emulation when it runs in single step mode:

QEMU changes the size of the SDL window to the smallest possible value
which is supported by the window manager. As this is not the calculated
size, QEMU switches to scaled mode. When the BIOS or the VGA driver sets
the normal text resolution, the window stays small and displays
microscopic characters.

Ignoring text resolutions of 1 x 1 or less avoids these problems.
A similar workaround already exists for too large resolutions.
