When executing a 64bit target chroot on 64bit host,
the ioctl() command can mismatch.

It seems the previous commit doesn't solve the problem in
my case:

    9c6bf9c7 linux-user: Fix ioctl cmd type mismatch on 64-bit targets

For example, a ppc64 chroot on an x86_64 host:

bash-4.3# ls
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x802c7415

The origin of the problem is in syscall.c:do_ioctl().

    static abi_long do_ioctl(int fd, abi_long cmd, abi_long arg)

In this case (ppc64) abi_long is long (on the x86_64), and

    cmd = 0x0000000080087467

then
    if (ie->target_cmd == cmd)

target_cmd is int, so target_cmd = 0x80087467
and to compare an int with a long, the sign is extended to 64bit,
so the comparison is:

    if (0xffffffff80087467 == 0x0000000080087467)

which doesn't match whereas it should.

This patch uses int in the case of the target command type
instead of abi_long.

The target payloads in cmsg conversions may not have the alignment
required by the host. Using the get_user and put_user functions is
the easiest way to handle this and also do the byte-swapping we
require.

(Note that prior to this commit target_to_host_cmsg was incorrectly
using __put_user() rather than __get_user() for the SCM_CREDENTIALS
conversion, which meant it wasn't getting the benefit of the
misalignment handling.)

The previous code for handling payload length when converting
cmsg structures from host to target had a number of problems:
 * we required the msg->msg_controllen to declare the buffer
   to have enough space for final trailing padding (we were
   checking against CMSG_SPACE), whereas the kernel does not
   require this, and common userspace code assumes this. (In
   particular, glibc's "try to talk to nscd" code that it will
   run on startup will receive a cmsg with a 4 byte payload and
   only allocate 4 bytes for it, which was causing us to do
   the wrong thing on architectures that need 8-alignment.)
 * we weren't correctly handling the fact that the SO_TIMESTAMP
   payload may be larger for the target than the host
 * we weren't marking the messages with MSG_CTRUNC when we did
   need to truncate a message that wasn't truncated by the host,
   but were instead logging a QEMU message; since truncation is
   always the result of a guest giving us an insufficiently
   sized buffer, we should report it to the guest as the kernel
   does and don't log anything

Rewrite the parts of the function that deal with length to
fix these issues, and add a comment in target_to_host_cmsg
to explain why the overflow logging it does is a QEMU bug,
not a guest issue.

For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.

The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.

This is to support R profile processors that may or may-not have an MPU
configured.

The old ARMv5-style page table format includes a kind of second level
descriptor named the "extended small page" format, whose primary purpose
is to allow specification of the TEX memory attribute bits on a 4K page.
This exists on ARMv6 and also (as an implementation extension) on XScale
CPUs; it's UNPREDICTABLE on v5.

We were mishandling this in two ways:
 (1) we weren't implementing it for v6 (probably never noticed because
Linux will use the new-style v6 page table format there)
 (2) we were not correctly setting the page_size, which is 4K, not 1K

The latter bug went unnoticed for years because the only thing which
the page_size affects is which TLB entries get flushed when the guest
does a TLB invalidate on an address in the page, and prior to commit
2f0d8631 we were doing a full TLB flush very frequently due to Linux's
habit of writing the SCTLR pointlessly a lot.

(We can assume that after commit 2f0d8631 the bug went unnoticed
for a year because nobody's actually using the Zaurus/XScale emulation...)

Report the correct page size for these descriptors, and permit them
on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus
can boot the kernel OK but gets random segfaults when it tries to
run userspace programs.

Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.
