48fc5de116 - Introduce kernel_kseg0_end variable that marks first address in KSEG0
available for use. All data below this address considered to be used
    by kernel. Along with kernel own data it might be symbol tables
    prepeared by trampoline code, boot loader service data passed for
    further analysis by kernel, etc... By default kernel_kseg0_end points
    to the end of loaded kernel.

- Introduce mips_postboot_fixup function. It checks for symbol information
    copied by ELF trampoline and passes it to KDB

9251d56f5f On LP64 struct ifid is 64-bit aligned while struct fid is 32-bit aligned
so on architectures with strict alignment requirements we can't just simply
cast the latter to the former but need to copy it bytewise instead.

29b6820f87 Merge r202882 from amd64/i386:
For PT_TO_SCE stop that stops the ptraced process upon syscall entry,
syscall arguments are collected before ptracestop() is called. As a
consequence, debugger cannot modify syscall or its arguments.

In syscall(), reread syscall number and arguments after ptracestop(),
if debugger modified anything in the process environment. Since procfs
stopevent requires number of syscall arguments in p_xstat, this cannot
be solved by moving stop/trace point before argument fetching.

Move the code to read arguments into separate function
fetch_syscall_args() to avoid code duplication. Note that ktrace point
for modified syscall is intentionally recorded twice, once with original
arguments, and second time with the arguments set by debugger.

PT_TO_SCX stop is executed after cpu_syscall_set_retval() already.

ce3853023f Fix breakage introduced to the tnt4882 driver in r202870. This PCI
frontend uses the same uPD7210 backend as the pcii ISA frontend, so
the backend has to cope with both situations.

Also, hide the first printf in pcii_probe (address mismatch) behind
bootverbose as the ISA bus parent tries to probe all configured ISA
devices against each driver, so a the console has been cluttered with
this message for a bunch of unrelated driver probes.

b0b9dee5c9 - Fix a race in sched_switch() of sched_4bsd.
In the case of the thread being on a sleepqueue or a turnstile, the
  sched_lock was acquired (without the aid of the td_lock interface) and
  the td_lock was dropped. This was going to break locking rules on other
  threads willing to access to the thread (via the td_lock interface) and
  modify his flags (allowed as long as the container lock was different
  by the one used in sched_switch).
  In order to prevent this situation, while sched_lock is acquired there
  the td_lock gets blocked. [0]
- Merge the ULE's internal function thread_block_switch() into the global
  thread_lock_block() and make the former semantic as the default for
  thread_lock_block(). This means that thread_lock_block() will not
  disable interrupts when called (and consequently thread_unlock_block()
  will not re-enabled them when called). This should be done manually
  when necessary.
  Note, however, that ULE's thread_unblock_switch() is not reaped
  because it does reflect a difference in semantic due in ULE (the
  td_lock may not be necessarilly still blocked_lock when calling this).
  While asymmetric, it does describe a remarkable difference in semantic
  that is good to keep in mind.

a7607816bf Just ignore the timestamps given to pututxline().
I've noticed many applications do a bad job at timekeeping, for several
reasons:

- Applications like screen(1) don't update time records when restoring
  the old user login record.
- Many applications only set ut_tv.tv_sec, not ut_tv.tv_usec.

This causes many problems for tools such as ac(8), which require the
timestamps to be properly ordered. This is why I've decided to let the
utmpx code obtain valid timestamps itself.

as they are no longer needed, we now just keep them around and free

72821110ac Overhaul of the pcii driver:
. Properly allocate all IO space resources.  These cards scatter their
  IO addresses over a range of 0x1600 bytes, and they require an
  additional address for "special interrupt handling".

. Implement the "special interrupt handling" per the GPIB-PCIIA
  Technical Reference Manual; this was apparently not declared for the
  clone card this driver has been originally implemented for, but it
  turned out to be needed for both, an original NI brand PCII/PCIIA
  card as well as the Axiom AX5488 clone.

. Add some diagnostic messages for various resource allocation etc.
  failures during probe.

. Add some comments about the structure of the IO address space that
  is used by these cards.

9b84f07357 This hopefully will fix the network problem I was seeing.
Basically the msg ring interrupt was being re-enabled
inside a spinlock as the thread set it self up for rescheduling.
This won't work since inside the re-enable is another
spin lock.. which means on return from the reenable
the  interrupts have been reenabled. Thus you would
get a clock int and end up panicing holding a spin
lock to long :-o
