Add support in gen-vdso-elfn.c.inc for the DT_PPC64_OPT
dynamic tag: this is an integer, so does not need relocation.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
Requires a relatively recent binutils version in order to avoid
spurious R_LARCH_NONE relocations. The presence of these relocs
are diagnosed by our gen-vdso tool.

This tool will be used for post-processing the linked vdso image,
turning it into something that is easy to include into elfload.c.

The vdso image will be pre-processed into a C data array, with
a simple list of relocations to perform, and identifying the
location of signal trampolines.

Aside from the section headers, we're unlikely to hit the
ImageSource cache on guest executables. But the interface
for imgsrc_read_* is better.

Change parse_elf_properties as well, as the bprm_buf argument

Rearrange the allocation of storage for ehdr between load_elf_image
and load_elf_binary. The same set of copies are done, but we don't
modify bprm_buf, which will be important later.

Rename the variable here to avoid that it shadows a variable from
the beginning of the function scope. With this change the code now
successfully compiles with -Wshadow=local.

This function is only used for compression. So we rename it as
compress_send_queued_data(). We put it on ram-compress.h because we
are moving it later to ram-compress.c.

After previous patch, we disable the posiblity that we use compression
together with xbzrle. So we can use directly migrate_compress().
Once there, now we don't need the rs parameter, so remove it.

When we detect that we have broken backwards compatibility in a
released version, we can't do anything for that version. But once we
fix that bug on the next released version, we can "mitigate" that
problem when migrating to new versions to give a way out of that
machine until it does a hard reboot.

This patch removes the code that ufs-lu was duplicating from
scsi-hd and allows them to share code.
It makes ufs-lu have a virtual scsi-bus and scsi-hd internally.
This allows scsi related commands to be passed thorugh to the scsi-hd.
The query request and nop command work the same as the existing logic.
Well-known lus do not have a virtual scsi-bus and scsi-hd, and
handle the necessary scsi commands by emulating them directly.

The MDIO access is done only on a write to the PHYMNTNC register. A
subsequent read is used to retrieve the result but does not trigger an
MDIO access by itself.
Refactor the PHY access logic to perform all accesses (MDIO reads and
writes) at PHYMNTNC write time.
