2b3f64cbf3 linux-user: Fix getdents emulation for 64 bit guest on 32 bit host 
Currently we mishandle emulation of the getdents syscall for the
case of a 64 bit guest on a 32 bit host -- it defaults into
the 'host and guest same size' codepath and generates incorrect
structures in the guest buffer.

We can't easily handle the 64-on-32 case using the host getdents
syscall, because the guest struct dirent is bigger than the
host struct dirent, and we might find the host syscall has handed
us back more records than we can fit in the guest buffer after
conversion. Instead, always emulate 64-on-32 getdents with
the host getdents64. This avoids the buffer-overrun problem
because a dirent64 struct is always the same size on any host
and always larger than any architecture's dirent struct.

b02ebad1dc linux-user: set minimum uname for RISC-V 
As support for RISC-V was only merged into the mainline kernel at 4.15
it is unlikely that glibc will be happy with a reported kernel version
of 3.8.0. Indeed when I testing binaries created by the current Debian
Sid compiler the tests failed with:

  FATAL: kernel too old

Bump the version to the minimum a RISC-V glibc would expect:

bb3ba35f20 linux-user: check that all of AArch64 SVE extended sigframe is writable 
In commit 8c5931de0a we added support for SVE extended
sigframe records.  These mean that the signal frame might now be
larger than the size of the target_rt_sigframe record, so make sure
we call lock_user on the entire frame size when we're creating it.
(The code for restoring the signal frame already correctly handles
the extended records by locking the 'extra' section separately to the
main section.)

In particular, this fixes a bug even for non-SVE signal frames,
because it extends the locked section to cover the
target_rt_frame_record. Previously this was part of 'struct
target_rt_sigframe', but in commit e1eecd1d9d we pulled
it out into its own struct, and so locking the target_rt_sigframe
alone doesn't cover it. This bug would mean that we would fail
to correctly handle the case where a signal was taken with
SP pointing 16 bytes into an unwritable page, with the page
immediately below it in memory being writable.

aac8f55633 linux-user/signal.c: Put AArch64 frame record in the right place 
AArch64 stack frames include a 'frame record' which holds a pointer
to the next frame record in the chain and the LR on entry to the
function. The procedure calling standard doesn't mandate where
exactly this frame record is in the stack frame, but for signal
frames the kernel puts it right at the top. We used to put it
there too, but in commit 7f0f4208b3 we accidentally put
the "enlarge to the 4K reserved space minimum" check after the
"allow for the frame record" code, rather than before it, with
the effect that the frame record would be inside the reserved
space and immediately after the last used part of it.

Move the frame record back out of the reserved space to where
we used to put it.

This bug shouldn't break any sensible guest code, but test
programs that deliberately look at the internal details
of the signal frame layout will not find what they are
expecting to see.

7f0f4208b3 linux-user/signal.c: Ensure AArch64 signal frame isn't too small 
The AArch64 signal frame design was extended for SVE in commit
8c5931de0a, so that instead of having a fixed setup we
now add various records to the frame, with some of them possibly
overflowing into an extra space outside the original 4K reserved
block in the target_sigcontext.  However, we failed to ensure that we
always at least allocate the 4K reserved block.  This is ABI, and
some userspace programs rely on it.  In particular the dash shell
would segfault if the frame wasn't as big enough.

(Compare the kernel's sigframe_size() function in
arch/arm64/kernel/signal.c.)

9ac225171c linux-user: fix preadv/pwritev offsets 
preadv/pwritev accept low and high parts of file offset in two separate
parameters. When host bitness doesn't match guest bitness these parts
must be appropriately recombined.
Introduce target_to_host_low_high that does this recombination and use
it in preadv/pwritev syscalls.

This fixes glibc testsuite test misc/tst-preadvwritev64.
