Introduce qemu_put_ram_ptr

This function allows to unlock a ram_ptr give by qemu_get_ram_ptr. After
a call to qemu_put_ram_ptr, the pointer may be unmap from QEMU when
used with Xen.

cpu-common: Modify cpu_physical_memory_read and cpu_physical_memory_write

A lot of calls don't operate on bytes but on words or on structured data.
So instead of a pointer to uint8_t, a void pointer is the better choice.

This allows removing many type casts....

cpu: add set_memory flag to request dirty logging

Add qemu_ram_remap

qemu_ram_remap() unmaps the specified RAM pages, then re-maps these
pages again. This is used by KVM HWPoison support to clear HWPoisoned
page tables across guest rebooting, so that a new page may be
allocated later to recover the memory error....

Introduce log_start/log_stop in CPUPhysMemoryClient

In order to use log_start/log_stop with Xen as well in the vga code,
this two operations have been put in CPUPhysMemoryClient.

The two new functions cpu_physical_log_start,cpu_physical_log_stop are
used in hw/vga.c and replace the kvm_log_start/stop. With this, vga does...

exec: introduce endianness swapped mmio

The way we're currently modeling mmio is too simplified. We assume that
every device has the same endianness as the target CPU. In reality,
most devices are little endian (all PCI and ISA ones I'm aware of). Some
are big endian (special system devices) and a very little fraction is...

migration: stable ram block ordering

This makes ram block ordering under migration stable, ordered by offset.
This is especially useful for migration to exec, for debugging.

Add qemu_ram_alloc_from_ptr function

Provide a function to add an allocated region of memory to the qemu RAM.

This patch is copied from Marcelo's qemu_ram_map() in qemu-kvm and given the

Greatly simplify the subpage implementation by not supporting

tcg: initial ia64 support

qemu: memory notifiers

This adds notifiers for phys memory changes: a set of callbacks that
vhost can register and update kernel accordingly. Down the road, kvm
code can be switched to use these as well, instead of calling kvm code
directly from exec.c as is done now....

Unbreak large mem support by removing kqemu

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.
