hw/pxa2xx.c: Fix handling of pxa2xx_i2c variable offset within region
The pxa2xx I2C controller can have its registers at an arbitrary offset
within the MemoryRegion it creates. We use this to create two controllers,
one which covers a region of size 0x10000 with registers starting at an
offset 0x1600 into that region, and a second one which covers a region
of size just 0x100 with the registers starting at the base of the region.
The implementation of this offsetting uses two qdev properties, "offset"
(which sets the offset which must be subtracted from the address to
get the offset into the actual register bank) and "size", which is the
size of the MemoryRegion. We were actually using "offset" for two
purposes: firstly the required one of handling the registers not being
at the base of the MemoryRegion, and secondly as a workaround for a
deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped
at a non-page boundary, the address passed into the read and write
functions would be the offset from the start of the page, not the
offset from the start of the MemoryRegion. So when calculating the value
to set the "offset" qdev property we included a rounding to a page
boundary.
Following commit 5312bd8b3 MemoryRegion read/write functions are now
correctly passed the offset from the base of the region, and our
workaround now means we're subtracting too much from addresses, resulting
in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90".
The fix for this is simply to remove the rounding to a page boundary;
this allows us to slightly simplify the expression since
base - (base & (~region_size)) == base & region_size
The qdev property "offset" itself must remain because it is still
performing its primary job of handling register banks not being at
the base of the MemoryRegion.

kvm: Comparison with ioctl number macros needs to be unsigned
In kvm-all.c we store an ioctl cmd number in the irqchip_inject_ioctl field
of KVMState, which has type 'int'. This seems to make sense since the
ioctl() man page says that the cmd parameter has type int.
However, the kernel treats ioctl numbers as unsigned - sys_ioctl() takes an
unsigned int, and the macros which generate ioctl numbers expand to
unsigned expressions. Furthermore, some ioctls (IOC_READ ioctls on x86
and IOC_WRITE ioctls on powerpc) have bit 31 set, and so would be negative
if interpreted as an int. This has the surprising and compile-breaking
consequence that in kvm_irqchip_set_irq() where we do:
return (s->irqchip_inject_ioctl == KVM_IRQ_LINE) ? 1 : event.status;
We will get a "comparison is always false due to limited range of data
type" warning from gcc if KVM_IRQ_LINE is one of the bit-31-set ioctls,
which it is on powerpc.
So, despite the fact that the man page and posix say ioctl numbers are
signed, they're actually unsigned. The kernel uses unsigned, the glibc
header uses unsigned long, and FreeBSD, NetBSD and OSX also use unsigned
long ioctl numbers in the code.
Therefore, this patch changes the variable to be unsigned, fixing the
compile.

For the pseries machine, TCE (IOMMU) tables can either be directly

However, even when KVM is persent, TCE acceleration is not always possible.
Only KVM HV supports this ioctl(), not KVM PR, or the kernel could run out

fall back on the malloc()ed table.
When a device is removed, and we need to remove the TCE table, we need to

qom/object.c: rename type_class_init() to type_initialize()
Function name type_class_init() gave us a wrong impression of separation
of type's "class" and "object" entities initialization. Name type_initialize()
is more appropriate for type_class_init() function (considering what operations
it performs).

qom: if @instance_size==0, assign size of object to parent object size
QOM documentation states that for objects of type with @instance_size == 0 size
will be assigned to match parent object's size. But currently this feauture is
not implemented and qemu asserts during creation of object with zero instance_size.
Set appropriate value for type instance_size during type_class_init() call.
object_initialize_with_type() must call type_class_init() before asserting
type->instance_size, and object_new_with_type() must call type_class_init() before
object allocation.

kvmvapic: align start address as well as size
The kvmvapic code remaps a section of ROM as RAM to allow the guest to
maintain state there. It is careful to align the section size to a page
boundary, to avoid creating subpages, but neglects to do the same for
the start address. These leads to an assert later on when the memory
core tries to create a page which is half RAM and half ROM.
Fix by aligning the start address to a page boundary.
This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none.
