Zbigniew Bodek 9920b3aa95 Don't allow malloc() to wait for resource while holding a lock in ITS
malloc() should not go to sleep in case of lack of resource while
the kernel thread is holding a non-sleepable lock.

- change malloc() flags to M_NOWAIT in such cases implement
  lpi_free_chunk() routine as it will be needed when ITT
  allocation fails in its_device_alloc_locked()
- do not increase verbosity of this code since upper layers will
  communicate an error if the interrupt setup fails

This is the top level of the FreeBSD source directory.  This file

$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree.  See build(7)
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The `buildkernel` and `installkernel` targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process.  See build(7), config(8),
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
for more information.

Note: If you want to build and install the kernel with the
`buildkernel` and `installkernel` targets, you might need to build
world before.  More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf
sub-directory.  GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
