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
clearer name qemu_ram_alloc_from_ptr().

qemu_ram_alloc: Add DeviceState and name parameters

These will be used to generate unique id strings for ramblocks. The name
field is required, the device pointer is optional as most callers don't
have a device. When there's no device or the device isn't a child of...

Remove IO_MEM_SUBWIDTH.

Greatly simplify the subpage implementation by not supporting
multiple devices at the same address at different widths. We
don't need full copies of mem_read/mem_write/opaque for each
address, only a single index back into the main io_mem_* arrays....

move targphys.h and hw/poison.h inclusion to cpu-common.h

With more files from outside the hw/ directory being placed into
libhw, avoid the need to include hw/hw.h for the sake of targ_phys_addr_t.

tcg: initial ia64 support

A few words about design choices:
  • On IA64, instructions should be grouped by bundle, and dependencies
    between instructions declared. A first version of this code tried to
    schedule instructions automatically, but was very complex and too...

Disable phsyical memory handling in userspace emulation.

Code to handle physical memory access is not meaningful in usrmode emulation,
so disable it.

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....

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

Get rid of _t suffix

Some not so obvious bits, slirp and Xen were left alone for the time
being.

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.

Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on...

Remove io_index argument from cpu_register_io_memory()

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Hardware convenience library

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target...
