[PULL 1/7] linux-user: implement mount_setattr(2)

[Helge Deller]

From: Matt Turner <mattst88@gmail.com>

mount_setattr() was in the syscall tables but had no implementation, so
guests always got -ENOSYS. systemd uses it when setting up per-unit
credential mounts, which fails the affected units with EXIT_CREDENTIALS.

struct mount_attr is an extensible struct like open_how, so handle it the
same way openat2() does: reject sizes smaller than the ver0 struct and
require any unknown trailing bytes to be zero. All of its fields are
64-bit, and the MOUNT_ATTR_* and MS_* propagation values are identical on
every target, so only the byte order needs fixing up.

[PULL 2/7] linux-user: support writing floating-point registers to a core dump

[Helge Deller]

From: Matt Turner <mattst88@gmail.com>

Write an NT_FPREGSET note for targets that opt in: a target_elf.h that
defines HAVE_ELF_CORE_FPREGS and target_elf_fpregset_t, and supplies an
elf_core_copy_fpregs() beside the existing elf_core_copy_regs().

[PULL 3/7] linux-user/alpha: write the floating-point registers to a core dump

[Helge Deller]

From: Matt Turner <mattst88@gmail.com>

A guest core carried only the general-purpose registers, so a debugger
opening one reported every floating-point register as unavailable --
including the arguments of the function that crashed.

Implement HAVE_ELF_CORE_FPREGS for Alpha: define target_elf_fpregset_t
to match the kernel's layout ($f0-$f30 plus the control register in the
slot $f31 would occupy) and fill it from elf_core_copy_fpregs().

Checked with lldb on a core from a program that faults with live values
in $f16 and $f17: both read back correctly, as does the control register.

[PULL 7/7] linux-user/sh4: write the floating-point registers to a core dump

Write an NT_FPREGSET note for SH4, matching struct user_fpu_struct
from arch/sh/include/asm/user.h: fr0-fr15, xf0-xf15, fpscr, fpul.
