a58b8d5401 ide: set WCACHE supported in IDENTIFY data
ATA does not only have the WCACHE enabled bit in identify word 85, but also
a WCACHE supported bit in word 82.  While the Linux kernel is fine with the
latter at least hdparm also needs the former before correctly displaying
the cache settings.  There's also a non-zero chance other operating systems
are more picky in their volatile write cache detection.

cd49692615 vmmouse: adapt to mouse handler changes.
This patch updates the vmmouse handler registration and activation.

Old behavior:
  vmmouse_read_id, vmmouse_request_relative and vmmouse_request_absolute
  unregister the handler and re-register it.

New behavior:
  vmmouse_request_relative and vmmouse_request_absolute will unregister
  the handler in case the mode did change.  Then register and active the
  handler with current mode if needed.

Note that the old code never ever *activates* the handler, so the
vmmouse doesn't receive events.  This trips up Fedora 14 for example:
Boot a default install without usb tablet, watch the X-Server activating
the vmmouse then, enjoy a non-functional mouse.

56d15a5329 [virtio-9p] Use preadv/pwritev instead of readv/writev
readv & writev, read & write respectively from the current offset
of the file & hence their use has to be preceeded by a call to lseek.
preadv/writev can be used instead, as they take the offset as an argument.
This saves one system call( lseek ).
In case preadv is not supported, it is implemented by an lseek
followed by a readv. Depending upon the configuration of QEMU, the
appropriate read & write methods are selected. This patch also fixes the
zero byte read/write bug & obviates the need to apply a fix for that bug separately.

0f8151cb75 [virtio-9p] Ignore O_DIRECT hint from client.
The O_DIRECT flag imposes alignment restrictions on the length and address
of userspace buffers and the file offset of I/Os.

While VirtFS/9P has plans to implement O_DIRECT behavior on the server,
for now we will stick to a behavior like NFS by bypassing the page cache
only on the client. Server may still cache the I/O.

Description

TGetlock is used to test for the existence of byte range posix locks on

      start[8] - Starting offset for lock
      length[8] - Number of bytes to lock
        If length is 0, lock all bytes starting at the location
        'start' through to the end of file
      proc_id[4] - process id that wants to take lock/owns the task

Description

Tlock is used to acquire/release byte range posix locks on a file

    flock structure:
        type[1] - Type of lock: F_RDLCK, F_WRLCK, F_UNLCK
        flags[4] - Flags could be either of
          P9_LOCK_FLAGS_BLOCK(1) - Blocked lock request, if there is a
            conflicting lock exists, wait for that lock to be released.
          P9_LOCK_FLAGS_RECLAIM(2) - Reclaim lock request, used when client is
            trying to reclaim a lock after a server restrart (due to crash)
        start[8] - Starting offset for lock
        length[8] - Number of bytes to lock
          If length is 0, lock all bytes starting at the location 'start'
          through to the end of file
        pid[4] - PID of the process that wants to take lock
        client_id[4] - Unique client id

        status[1] - Status of the lock request, can be
          P9_LOCK_SUCCESS(0), P9_LOCK_BLOCKED(1), P9_LOCK_ERROR(2) or
          P9_LOCK_GRACE(3)
          P9_LOCK_SUCCESS - Request was successful
          P9_LOCK_BLOCKED - A conflicting lock is held by another process
          P9_LOCK_ERROR - Error while processing the lock request
          P9_LOCK_GRACE - Server is in grace period, it can't accept new lock
                requests in this period (except locks with
                P9_LOCK_FLAGS_RECLAIM flag set)

ab03b63d7a [virtio-9p] open should not return EBADF
When 9P server fails to create a file due to permission problems it should
return EPERM. However the current 9P2000.L code returns EBADF. EBADF is NOT
a valid return value from open() call.

The problem is because we do not preserve the errno variable properly. If the
file open had failed, the call to close() on the fd in v9fs_post_lcreate()
fails and sets errno to EBADF. We should preserve the errno that we got from
open() and we should call close() only if we had a valid fd.

010ec62934 eepro100: Add support for multiple individual addresses (multiple IA)
I reviewed the latest sources of Linux, FreeBSD and NetBSD.
They all reset the multiple IA bit (multi_ia in BSD) to zero,
but I did not find code which sets this bit to one
(like it is done by some routers).

Running Windows guests also did not set this bit.

Intel's Open Source Software Developer Manual does not
give much information on the semantics related to this bit,
so I had to guess how it works. The guess was good enough
to make the router emulation work.

Related changes in this patch:
* Update naming and documentation of the internal hash register.
  It is not limited to multicast, but also used for multiple IA.
* Dump complete configuration register when debug traces are enabled.
* Debug output when multiple IA bit is set during CmdConfigure.
* Debug output when frames are received because multiple IA bit is set,
  or when they are ignored although it is set.

e78815a554 Introduce qemu_madvise()
vl.c has a Sun-specific hack to supply a prototype for madvise(),
but the call site has apparently moved to arch_init.c.

Haiku doesn't implement madvise() in favor of posix_madvise().
OpenBSD and Solaris 10 don't implement posix_madvise() but madvise().
MinGW implements neither.

Check for madvise() and posix_madvise() in configure and supply qemu_madvise()
as wrapper. Prefer madvise() over posix_madvise() due to flag availability.
Convert all callers to use qemu_madvise() and QEMU_MADV_*.

Note that on Solaris the warning is fixed by moving the madvise() prototype,
not by qemu_madvise() itself. It helps with porting though, and it simplifies
most call sites.

v7 -> v8:
* Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl.

v6 -> v7:
* Adopt madvise() rather than posix_madvise() semantics for returning errors.
* Use EINVAL in place of ENOTSUP.

v5 -> v6:
* Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID.
  Spotted by Blue Swirl.

v4 -> v5:
* Introduce QEMU_MADV_INVALID, suggested by Alexander Graf.
  Note that this relies on -1 not being a valid advice value.

v3 -> v4:
* Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl.
  This will currently break the check in kvm-all.c by calling madvise() with
  a supported flag, which will not fail. Ideas/patches welcome.

v2 -> v3:
* Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf.
* Add configure check for madvise(), too.
  Add defines to Makefile, not QEMU_CFLAGS.
  Convert all callers, untested. Suggested by Blue Swirl.
* Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf.
* Display configure check results.

v1 -> v2:
* Don't rely on posix_madvise() availability, add qemu_madvise().
  Suggested by Blue Swirl.

interrupts while the 440's signal DECR.

f8b6d67251 scsi-generic: add missing reset handler
Ensure that pending requests of a SCSI generic device are purged on
system reset. This also avoids calling a NULL function in lsi53c895a.
The lsi code was recently changed to call the .qdev.reset function.

1b2adf2803 ide: propagate the required alignment
IDE is a bit ugly in this respect.  For one it doesn't really keep track
of a sector size - most of the protocol is in units of 512 bytes, and we
assume 2048 bytes for CDROMs which is correct most of the time.

Second IDE allocates an I/O buffer long before we know if we're dealing
with a CDROM or not, so increase the alignment for the io_buffer
unconditionally.
