a9d505a22a Split the vm_page flags PG_WRITEABLE and PG_REFERENCED into atomic
flags field. Updates to the atomic flags are performed using the atomic
ops on the containing word, do not require any vm lock to be held, and
are non-blocking. The vm_page_aflag_set(9) and vm_page_aflag_clear(9)
functions are provided to modify afalgs.

Document the changes to flags field to only require the page lock.

Introduce vm_page_reference(9) function to provide a stable KPI and
KBI for filesystems like tmpfs and zfs which need to mark a page as
referenced.

a6bb123606 Do not use the function pointers for the internal operation of rtld_printf()
functions. The _rtld_error() function might be called early during the rtld
bootstrap, in which case function pointers are not yet functional on ia64

a3cb964a30 The maximum read size of incoming packets is done in 1024-byte increments.
The current code was rounding down the maximum frame size instead of
routing up, resulting in a read size of 1024 bytes, in the non-jumbo
frame case, and splitting the packets across multiple mbufs.

Consequently the above problem exposed another issue, which is when
packets were splitted across multiple mbufs, and all of the mbufs in the
chain have the M_PKTHDR flag set.

* Update the hardware access register definitions and functions to bring
  them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
  PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
  which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support

ef6fc882ac Interrupts are disabled/enabled when entering and exiting the KDB context.
While this is generally good, it brings along a serie of problems,
like clocks going off sync and in presence of SW_WATCHDOG, watchdogs
firing without a good reason (missed hardclock wdog ticks update).

Fix the latter by kicking the watchdog just before to re-enable the interrupts.
Also, while here, not rely on users to stop the watchdog manually when
entering DDB but do that when entering KDB context.

8e7c067b29 When libexec/rtld-elf/rtld.c is compiled with clang, the r_debug_state()
function (a hook necessary for gdb support), is inlined, but since the
function contains no code, no calls to it are generated.  When gdb is
debugging a dynamically linked program, this causes backtraces to be
corrupted.

Fix it by marking the function __noinline, and inserting an empty asm
statement, that pretends to clobber memory.  This forces the compiler to
emit calls to r_debug_state() throughout rtld.c.

3c6157dcec Correct several issues in the integration of POSIX shared memory objects
and the new setmode and setowner fileops in FreeBSD 9.0:

- Add new MAC Framework entry point mac_posixshm_check_create() to allow
  MAC policies to authorise shared memory use.  Provide a stub policy and
  test policy templates.

- Add missing Biba and MLS implementations of mac_posixshm_check_setmode()
  and mac_posixshm_check_setowner().

- Add 'accmode' argument to mac_posixshm_check_open() -- unlike the
  mac_posixsem_check_open() entry point it was modeled on, the access mode
  is required as shared memory access can be read-only as well as writable;
  this isn't true of POSIX semaphores.

- Implement full range of POSIX shared memory entry points for Biba and MLS.

0e6cabaab1 Fix the check in dircheck() on namlen.
The value of namlen is copied from on-disk d_namlen, which is a 8-bit
unsigned integer which can never exceed MAXNAMLEN (255) so the test is
always true.  Moreover, UFS does not allow d_namelen being zero.

Change namlen from u_int to u_int8_t, and replace the unneeded test
with a useful test.
