The ARM EABI specifies that 64 bit integers should be
8 aligned; remove our incorrect setting of 4 alignment.
This has no actual effect since it only set the alignment
for the 'abi_ullong' and 'abi_llong' types, which are used
only inside code which is MIPS-specific, but it will
avoid problems later if we use the types elsewhere.

This patch partially implements the e1000 interrupt mitigation mechanisms.
Using a single QEMUTimer, it emulates the ITR register (which is the newer
mitigation register, recommended by Intel) and approximately emulates
RADV and TADV registers. TIDV and RDTR register functionalities are not
emulated (RDTR is only used to validate RADV, according to the e1000 specs).
RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation
mechanism and would need a timer each to be completely emulated. However,
a single timer has been used in order to reach a good compromise between
emulation accuracy and simplicity/efficiency.
The implemented mechanism can be enabled/disabled specifying the command
line e1000-specific boolean parameter "mitigation", e.g.
qemu-system-x86_64 -device e1000,mitigation=on,... ...
For more information, see the Software developer's manual at
http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf.
Interrupt mitigation boosts performance when the guest suffers from
an high interrupt rate (i.e. receiving short UDP packets at high packet
rate). For some numerical results see the following link

Define the return value of get_block_status. Bits 0, 1, 2 and 9-62
are valid; bit 63 (the sign bit) is reserved for errors. Bits 3-8
are left for future extensions.
The return code is compatible with the old is_allocated API: if a driver
only returns 0 or 1 (aka BDRV_BLOCK_DATA) like is_allocated used to,
clients of is_allocated will not have any change in behavior. Still,
we will return more precise information in the next patches and the
new definition of bdrv_is_allocated is already prepared for this.

For now, bdrv_get_block_status is just another name for bdrv_is_allocated.
The next patches will add more flags.
This also touches all block drivers with a mostly mechanical rename. The
sole exception is cow; because it calls cow_co_is_allocated from the read
code, we keep that function and make cow_co_get_block_status a wrapper.

This is an identical change because effectively, there's no multiple

A loop can be considered more efficient than function calls in a loop,

instead.

Always define GETRA; use __builtin_extract_return_addr, rather than

Rename GETPC_LDST to GETRA_LDST to indicate that it does not
contain the GETPC_ADJ value. Likewise with GETPC_EXT to GETRA_EXT.
Perform the GETPC_ADJ adjustment inside helper_ret_ld/st. This will
allow backends to pass along the "true" return address rather than
the massaged GETPC value. In the meantime, double application of
GETPC_ADJ does not hurt, since the call insn in all ISAs is at least

Therefore MSIMessage handling is completely hidden in QEMU.
Previously every sPAPR PCI host bridge implemented its own MSI window
to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci
or vfio) and route them to the guest via qemu_pulse_irq().
MSIMessage used to be encoded as:
.addr - address within the PHB MSI window;
.data - the device index on PHB plus vector number.
The MSI MR write function translated this MSIMessage to a global IRQ
number and called qemu_pulse_irq().
However the total number of IRQs is not really big (at the moment it is
1024 IRQs starting from 4096) and even 16bit data field of MSIMessage
seems to be enough to store an IRQ number there.
This simplifies MSI handling in sPAPR PHB. Specifically, this does:
1. remove a MSI window from a PHB;
2. add a single memory region for all MSIs to sPAPREnvironment
and spapr_pci_msi_init() to initialize it;
3. encode MSIMessage as:
* .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL;
* .data as an IRQ number.
4. change IRQ allocator to align first IRQ number in a block for MSI.
MSI uses lower bits to specify the vector number so the first IRQ has to
be aligned. MSIX does not need any special allocator though.

We have a lot of code duplication between machine types,
this increases with each new machine type
and each new field.
This has already introduced a minor bug: description
for pc-1.3 says "Standard PC" while description for
pc-1.4 is "Standard PC (i440FX + PIIX, 1996)"
which makes you think 1.3 is somehow more standard,
or newer, while in fact it's a revision of the same PC.
This patch addresses this issue by using macros, along
the lines used by PC_COMPAT_X_X - only for
non-property options.
The approach can extend to non-PC machine types.
