w64: Fix data type of next_tb and tcg_qemu_tb_exec
next_tb is the numeric value of a tcg target (= QEMU host) address.
Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).
The type cast '(long)(next_tb & ~3)' was not needed (casting
unsigned long to long does not change the bits, and nor does
casting long to pointer for most (= all non w64) hosts.
It is removed here.
Macro or function tcg_qemu_tb_exec is used to set next_tb.
The function also returns next_tb. Therefore tcg_qemu_tb_exec
must return a tcg_target_ulong.

Currently, the function spapr_create_phb() uses its parameters to
initialize the correct memory windows for the new PCI Host Bridge
(PHB). This is not the way things are supposed to be done with qdevs,
and means you can't create extra PHBs easily using -device.
Since pSeries machines can and do have many PHBs with various
configurations, this is a real limitation, not just a theoretical.
This patch, therefore, alters the PHB initialization code to use qdev
properties to set these parameters of the new bridge, moving most of
the code from spapr_create_phb() to spapr_phb_init().
While we're at it, we change the naming of each PCI bus and its

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.

The pseries "xics" interrupt controller, like most interrupt
controllers can support both message (i.e. edge sensitive) interrupts
and level sensitive interrupts, but it needs to know which are which.
When I implemented the xics emulation for qemu, the only devices we
supported were the PAPR virtual IO devices. These devices only use
message interrupts, so they were the only ones I implemented in xics.
Since then, however, we have added support for PCI devices, which use
level sensitive interrupts. It turns out the message interrupt logic
still actually works most of the time for these, but there are
circumstances where we can lost interrupts due to the incorrect
interrupt logic.

interrupt logic. The type of the interrupt is set when a device

For the pseries machine, TCE (IOMMU) tables can either be directly
malloc()ed in qemu or, when running on a KVM which supports it, mmap()ed
from a KVM ioctl. The latter option is used when available, because it
allows the (frequent bottlenext) H_PUT_TCE hypercall to be KVM accelerated.
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
of contiguous memory to allocate the new table. In this case we need to
fall back on the malloc()ed table.
When a device is removed, and we need to remove the TCE table, we need to
either munmap() or free() the table as appropriate for how it was
allocated. The code is supposed to do that, but we buggily fail to
initialize the tcet->fd variable in the malloc() case, which is used as a
flag to determine which is the right choice.

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.

Casting a pointer to an integer value must use uintptr_t or intptr_t
(not long) for portable code. MinGW-w64 requires this because
sizeof(long) != sizeof(void *) for w64 hosts, so casting to long
raises a compiler warning.
I use uintptr_t instead of intptr_t because changing the sign does not
matter here and casting pointers to unsigned values seems more
reasonable (the unsigned value is a non negative offset.

walking the queues from the top again - that couldn't work. Now we pre-

safely be removed if it was sent successfully. We also need to take into
