Gerd Hoffmann f90e160b50 Revert "xhci: Fix number of streams allocated when using streams"
This reverts commit d063c3112c.

"2 << x" is the same as "2 ^ (x + 1)", so the old code is correct.

Jack Un cae7f29c47 Fix OHCI ISO TD state never being written back.
There appears to be typo in OHCI with isochronous transfers
resulting in isoch. transfer descriptor state never being written back.
The'put_words' function is in a OR statement hence it is never called.

Markus Armbruster 830cd54fca usb: Fix bootindex for portnr > 9
We identify devices by their Open Firmware device paths.  The encoding
of the host controller and hub port numbers is incorrect:
usb_get_fw_dev_path() formats them in decimal, while SeaBIOS uses
hexadecimal.  When some port number > 9, SeaBIOS will miss the
bootindex (lucky case), or apply it to another device (unlucky case).

The relevant spec[*] agrees with SeaBIOS (and OVMF, for that matter).
Change %d to %x.

Bug can bite only with host controllers or hubs sporting more than ten
ports.  I'm not aware of any.

Stefan Weil bcc55f327c po: Fix Makefile rules for in-tree builds without configuration
Adding 'update' to the phony targets fixes this error:

$ LANG=C make -C po update
make: Entering directory `/qemu/po'
  LINK  update
/qemu/po/de_DE.po: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
make: *** [update] Error 1
make: Leaving directory `/qemu/po'

Some other phony targets (build, install) were also added, and the
existing .PHONY statement was moved to a more prominent position at
the beginning of the Makefile.

The patch also fixes a 2nd bug. The default target should be 'all',
but instead 'modules' (from rules.mak) was the default. Fix this by
adding 'all' as a target before any include statement.

Max Reitz bd39e6ed0b qemu-img: Allow cache mode specification for amend
qemu-img amend may extensively modify the target image, depending on the
options to be amended (e.g. conversion to qcow2 compat level 0.10 from
1.1 for an image with many unallocated zero clusters). Therefore it
makes sense to allow the user to specify the cache mode to be used.

Max Reitz 40055951a7 qemu-img: Allow source cache mode specification
Many qemu-img subcommands only read the source file(s) once. For these
use cases, a full write-back cache is unnecessary and mainly clutters
host cache memory. Though this is generally no concern as cache memory
is freely available and can be scaled by the host OS, it may become a
concern with thin provisioning.

For these cases, it makes sense to allow users to freely specify the
source cache mode (e.g. use no cache at all).

This commit adds a new switch (-T) for the qemu-img subcommands check,
compare, convert and rebase to specify the cache to be used for source
images (the backing file in case of rebase).

Tom Musta 29560a6cb7 linux-user: writev Partial Writes
Although not technically not required by POSIX, the writev system call will
typically write out its buffers individually.  That is, if the first buffer
is written successfully, but the second buffer pointer is invalid, then
the first chuck will be written and its size is returned.

Tom Musta 6f6a40328b linux-user: Support target-to-host translation of mlockall argument
The argument to the mlockall system call is not necessarily the same on
all platforms and thus may require translation prior to passing to the
host.

For example, PowerPC 64 bit platforms define values for MCL_CURRENT
(0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms
(0x1 and 0x2, respectively)

Tom Musta 8fbe8fdfbc linux-user: clock_nanosleep errno Handling on PPC
The clock_nanosleep syscall is unusual in that it returns positive
numbers in error handling situations, versus returning -1 and setting
errno, or returning a negative errno value.  On POWER, the kernel will
set the SO bit of CR0 to indicate failure in a syscall.  QEMU has
generic handling to do this for syscalls with standard return values.

Add special case code for clock_nanosleep to handle CR0 properly.

Tom Musta 37ed09560c linux-user: Make ipc syscall's third argument an abi_long
For those target ABIs that use the ipc system call (e.g. POWER),
the third argument is used in the shmat path as a pointer.  It
therefore must be declared as an abi_long (versus int) so that
the address bits are not lost in truncation.  In fact, all arguments
to do_ipc should be declared as abit_long.

In fact, it makes more sense for all of the arguments to be declaried
as abi_long (except call).

Tom Musta 5464baecf5 linux-user: Properly Handle semun Structure In Cross-Endian Situations
The semun union used in the semctl system call contains both an int (val) and
pointers.  In cross-endian situations on 64 bit targets, the value passed to
semctl is an 8 byte (abi_long) value and thus does not have the 4-byte val
field in the correct location.  In order to rectify this, the other half
of the union must be accessed.  This is achieved in code by performing
a byte swap on the entire 8 byte union, followed by a 4-byte swap of the
first half.

Also, eliminate an extraneous (dead) line of code that sets target_su.val in
the IPC_SET/IPC_GET case.
