In hw/arm and include/hw/arm, some source files for the OMAP SoC
and the sx1 boards that are our only remaining OMAP boards still
have hard-coded tabs (almost entirely used for the indent on
inline comments, not for actual code indent).
Replace the tabs with spaces using vim :retab. I used 4 spaces
except in some defines and comments where I tried to put
everything aligned in the same column for better readability.
This commit is a purely whitespace-only change.

Currently we call gdb_init_cpu() in cpu_common_initfn(), which is
very early in the CPU object's init->realize creation sequence. In
particular this happens before the architecture-specific subclass's
init fn has even run. This means that gdb_init_cpu() can only do
things that depend strictly on the class, not on the object, because
the CPUState* that it is passed is currently half-initialized.
In commit a1f728ecc9 we accidentally broke this rule, by adding
a call to the gdb_get_core_xml_file method which takes the CPUState.
At the moment we get away with this because the only implementation
doesn't actually look at the pointer it is passed. However the whole
reason we created that method was so that we could make the "which
XML file?" decision based on a property of the CPU object, and we
currently can't change the Arm implementation of the method to do
what we want without causing wrong behaviour or a crash.
The ordering restrictions here are:
* we must call gdb_init_cpu before:
- any call to gdb_register_coprocessor()
- any use of the gdb_num_regs field (this is only used
in code that's about to call gdb_register_coprocessor()
and wants to know the first register number of the
set of registers it's about to add)
* we must call gdb_init_cpu after CPU properties have been
set, which is to say somewhere in realize
The function cpu_exec_realizefn() meets both of these requirements,
as it is called by the architecture-specific CPU realize function
early in realize, before any calls ot gdb_register_coprocessor().
Move the gdb_init_cpu() call to there.

When only the -kernel parameter is used to load the elf kernel, the initrd
is loaded in the ram. If the initrd size is too large, the loading fails,
resulting in a VM startup failure. This patch first loads initrd near
the kernel.
When the nearby memory space of the kernel is insufficient, it tries to
load it to the starting position of high memory. If there is still not
enough, qemu will report an error and ask the user to increase the memory
space for the virtual machine to boot.

although we have not yet introduced another subclass, so all the

Note that currently there is no need for additional data for
TYPE_VFIO_PCI, so it shares the same C struct type as

Instead of requesting region information on demand with
VFIO_DEVICE_GET_REGION_INFO, maintain a cache: this will become
necessary for performance for vfio-user, where this call becomes a
message over the control socket, so is of higher overhead than the
traditional path.
We will also need it to generalize region accesses, as that means we
can't use ->config_offset for configuration space accesses, but must
look up the region offset (if relevant) each time.

For vfio-user, device operations such as IRQ handling and region
read/writes are implemented in userspace over the control socket, not
ioctl() to the vfio kernel driver; add an ops vector to generalize this,
and implement vfio_device_io_ops_ioctl for interacting with the kernel
vfio driver.

Various bits of code that call vfio device APIs should consistently use
the "return -errno" approach for passing errors back, rather than
presuming errno is (still) set correctly.

Add a helper similar to vfio_device_get_region_info() and use it
everywhere.
Replace a couple of needless allocations with stack variables.
As a side-effect, this fixes a minor error reporting issue in the call
from vfio_msix_early_setup().

Allow attachment by explicitly passing a TYPE_VFIO_IOMMU_* string;
vfio-user will use this later.
