Daniel P. Berrangé 6d5d5dde9a linux-user: fix to handle variably sized SIOCGSTAMP with new kernels
The SIOCGSTAMP symbol was previously defined in the
asm-generic/sockios.h header file. QEMU sees that header
indirectly via sys/socket.h

In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
Instead it provides only SIOCGSTAMP_OLD, which only uses a
32-bit time_t on 32-bit architectures.

The linux/sockios.h header then defines SIOCGSTAMP using
either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
on 32-bit architectures

To cope with this we must now convert the old and new type from
the target to the host one.

Cortland Tölva a133367ec1 linux-user: Implement special usbfs ioctls.
Userspace submits a USB Request Buffer to the kernel, optionally
discards it, and finally reaps the URB.  Thunk buffers from target
to host and back.

Tested by running an i386 scanner driver on ARMv7 and by running
the PowerPC lsusb utility on x86_64.  The discardurb ioctl is
not exercised in these tests.

Peter Maydell f2c2fb50be linux-user: Correct type for LOOP_GET_STATUS{,64} ioctls
The LOOP_GET_STATUS and LOOP_GET_STATUS64 ioctls were incorrectly
defined as IOC_W rather than IOC_R, which meant we weren't
correctly copying the information back from the kernel to the guest.
The loop_info64 structure definition was also missing a member
and using the wrong type for several 32-bit fields.

In particular, this meant that "kpartx -d image.img" didn't work
and "losetup -a" behaved strangely. Correct the ioctl type definitions.

Alexander Graf a59b5e35d1 linux-user: Convert blkpg to use a special subop handler
The blkpg ioctl can take different payloads depending on the opcode in
its payload structure. Create a new special ioctl handler that can only
deal with partition style ones for now.

This patch fixes running parted for me.

Fix the SNDCTL_DSP_MAP{IN,OUT}BUF ioctl definitions so that they
refer to a suitably defined target struct layout rather than hardcoding
the ioctl number. This fixes complaints from the syscall_init()

The compat LOOP_SET_STATUS ioctl uses struct old_dev_t in its passed
