This new tracetool "format" generates a SystemTap .stp file that outputs
simpletrace binary trace data.
In contrast to simpletrace or ftrace, SystemTap does not define its own
trace format. All output from SystemTap is generated by .stp files.
This patch lets us generate a .stp file that outputs
It can be useful to read simpletrace files that have no header. For

Currently, if the block device backing the IDE drive is resized,
the information about the device as cached inside of the IDEState
structure is not updated, thus when a guest OS re-queries the drive,
it is unable to see the expanded size.
This patch adds a resize callback to correct this, and mark

This series of patches is the result of executing the Linux Test Program

on the 64 bit big and little endian linux user mode targets for Power.
Some of the changes are not technically unique to Power, but are effectively
so. For
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 h
The mq_open system call takes an optional struct mq_attr pointer
argument in the fourth position. This pointer is used when O_CREAT
is specified in the flags (second) argument. It may be NULL, in
which case the queue is created with implementation defined attributes.

The 64 bit PowerPC platforms eliminate the _unused1 and _unused2
elements of the semid_ds structure from . So eliminate
these from the target_semid_ds structure.

The msgsnd system call takes an argument that describes the message

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 th
When the ipc system call is used to wrap a semctl system call,
the ptr argument to ipc needs to be dereferenced prior to passing
it to the semctl handler. This is because the fourth argument to
semctl is a union and not a pointer to a union.

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.

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

The curl hardcoded timeout (5 seconds) sometimes is not long
enough depending on the remote server configuration and network
traffic. The user should be able to set how much long he is
willing to wait for the connection.
Adding a new option to set this timeout gives the user this
