506e9a3a87 Fix the LINUX_SOUND_MIXER_INFO ioctl to return success after the
information is set to FreeBSD.  It had been falling through to the end
of linux_ioctl_sound() and returning ENOIOCTL.  Noticed when running the
Linux ALSA amixer tool.

Add a LINUX_SOUND_MIXER_READ_CAPS ioctl which is used by the Skype
v2.1.0.81 binary.

a94ca271e7 Some drivers rely on the existence of certain keys. The Atheros 9xxx
driver for example requests the NetCfgInstanceId but doesn't check the

823fc080d7 Resurrect amd64 support.
- Many drivers on amd64 are picking system uptime, interrupt time and ticks
  via global data structure instead of calling functions for performance
  reasons. For now just patch such address so driver will not trigger page
  fault when trying to access such data. In future, additional callout may
  be added to update data in periodic intervals.
- On amd64 we need to allocate "shadow space" on stack before calling any
  function.

7f08176ee8 Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
  storing thread specific, miscellaneous, informations. Right now it is
  just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

526384ecf2 Do not take the process lock. The assignment to u_short inside the
properly aligned structure is atomic on all supported architectures, and
the thread that should see side-effect of assignment is the same thread

bb63fdde6d By using the 32-bit Linux version of Sun's Java Development Kit 1.6
on FreeBSD (amd64), invocations of "javac" (or "java") eventually
end with the output of "Killed" and exit code 137.

This is caused by:
1. After calling exec() in multithreaded linux program threads are not
   destroyed and continue running. They get killed after program being
   executed finishes.

2. linux_exit_group doesn't return correct exit code when called not
   from group leader. Which happens regularly using sun jvm.

The submitters fix this in a similar way to how NetBSD handles this.

I took the PRs away from dchagin, who seems to be out of touch of
this since a while (no response from him).

The patches committed here are from [2], with some little modifications
from me to the style.

511fa5ac98 Fix a panic on i386 for drivers using MmAllocateContiguousMemory()
and MmAllocateContiguousMemorySpecifyCache().

Those two functions take 64-bit variable(s) for their arguments. On i386
that takes additional 32-bit variable per argument. This is required so
that windrv_wrap() can correctly wrap function that miniport driver calls
with stdcall convention. Similar explanation is provided in subr_ndis.c for
other functions.

be44a97cd9 - print out the PID and program name of the program trying to use an
unsupported futex operation
- for those futex operations which are known to be not supported,
  print out which futex operation it is
- shortcut the error return of the unsupported FUTEX_CLOCK_REALTIME in
  some cases:
    FUTEX_CLOCK_REALTIME can be used to tell linux to use
    CLOCK_REALTIME instead of CLOCK_MONOTONIC. FUTEX_CLOCK_REALTIME
    however must only be set, if either FUTEX_WAIT_BITSET or
    FUTEX_WAIT_REQUEUE_PI are set too. If that's not the case
    we can die with ENOSYS right at the beginning.

78ae4338a2 Add macro DECLARE_MODULE_TIED to denote a module as requiring the
kernel of exactly the same __FreeBSD_version as the headers module was
compiled against.

Mark our in-tree ABI emulators with DECLARE_MODULE_TIED. The modules
use kernel interfaces that the Release Engineering Team feel are not
stable enough to guarantee they will not change during the life cycle
of a STABLE branch. In particular, the layout of struct sysentvec is
declared to be not part of the STABLE KBI.

- correctly add '\0' at the end of each copied string;
- fix style.

- unlock the process before calling copyin code [1]. The process is held

- use linprocfs_doargv() to handle !curproc case for which p_args is not cached.
