At present there are two callers of get_tmp_filename() and they are
inconsistent.
One does:
/* TODO: extra byte is a hack to ensure MAX_PATH space on Windows. */
char *tmp_filename = g_malloc0(PATH_MAX + 1);
...
ret = get_tmp_filename(tmp_filename, PATH_MAX + 1);

The support of single-stepping is very much dependent on support from
the accelerator we are using. To avoid special casing in gdbstub move
the probing out to an AccelClass function so future accelerators can

As HW virtualization requires specific support to handle breakpoints
lets push out special casing out of the core gdbstub code and into
AccelOpsClass. This will make it easier to add other accelerator

Both arm_cpu_tlb_fill (for normal IO) and
arm_cpu_get_phys_page_attrs_debug (for debug access) come through
get_phys_addr which is setting the other memory attributes for the
transaction. As these are all by definition CPU accesses we can also
set the requested_type/index as appropriate.

Use exec_path to re-execute the binary from /proc/self/exe
Fix do_openat() that should not use execfd.
v2:
- don't use execfd as it can't be closed and is usable by the child
Laurent Vivier (2):
linux-user: handle /proc/self/exe with execve() syscall
linux-user: don't use AT_EXECFD in

Update the TPM documentation for usage of a TPM 2 rather than a TPM 1.2.
Adjust the command lines and expected outputs inside the VM accordingly.
Update the command line to start a TPM 2 with swtpm.

I noticed today that docs/specs/pci-ids.txt doesn't have
an entry for the virtio-iommu, which is defined in pci.h as
#define PCI_DEVICE_ID_VIRTIO_IOMMU 0x1014
There seem to be a few other virtio ID values defined in the
header but not in the txt file too -- do we need to update it?
