fe4f1dfc8f Alfred got me thinking. Provide stubs for lint, and let the compilers
themselves cause a failure if it is told to use a __widget that there is
no implementation for them.  missing an implementation for __unused etc is
harmless.  But not having a __packed implementation when the kernel code
really needs it is a big deal.

a7865fc147 Add a __section(x) macro as well. Use this in linker_set.h. ie:
static void const * const __set_##set##_sym_##sym
 __attribute__((__section__("set_" #set),__unused__)) = &sym
becomes:
static void const * const __set_##set##_sym_##sym
 __section("set_" #set) __unused = &sym
Like the other macros, these #define away for unrecognized compilers or
lint.

Also, fix the argments in the previous commit for the non-gcc case. lint
might be a bit happier about that.  Note that the gcc <= 2.6 case
needs some research.

c692fbe091 At great personal risk, add a __packed and __aligned(x) define that
expand to __attribute__((packed)) and __attribute__((aligned(x)))
respectively.  Replace the handful of gcc-ism's that use
__attribute__((aligned(16))) etc around the kernel with __aligned(16).

There are over 400 __attribute__((packed)) to deal with, that can come
later.  I just want to use __packed in new code rather than add more
gcc-ism's.

77e22cb706 Wads more cleanup...
In mpttimeout, call mpt_intr just on the offchance that we missed
an interrupt. We can check to see whether or not the command that
is timing out got completed.

When we *do* decide to timeout a command, set the command state to
REQ_TIMEOUT and then invoke another timeout (hz/10)- mpttimeout2.
This allows us to catch a couple cases we've seen where the command
we timed out on in fact is ready to be completed by the firmware.
In any case, it's only after mpttimeout2 is called that we actually
take down the private state and free the request itself. CAM has
been notified in mpttimeout anyway. This whole area should be redone,
but that will take 105% of my available game time for this month.

Fix a couple of missing (and not useful, at presnet) CAMLOCK_2_MPTLOCK
and MPTLOCK_2_CAMLOCK locations.

Split mpt_notify into mpt_ctlop, which handles all reply completions
that have 0x800000000 or'd into the ContextID. This function can, in
fact, call mpt_event_notify_reply, which handles the traditional
async event notifications. While we're at it, put in the extremely
important (but currently untested) code that send back an Ack to
an Event Notification (if the Event Notification is marked with
AckRequired). Note that an Ack also generates another ctlop completion,
tra la.

Fix up mpt_done substantially to try and get how we plug into CAM
correctly done. Remove bogus CAM_RELEASE_SIMQ settings.

Do some cleanups in mpt_action that are related to speed negotiation
for Ultra4 cards. This is an area that is still quite fragile and
worrisome as config data being read back often doesn't make sense or
jibe with the documentation.

At any rate, after these changes were done, I was finally able to
get Lars Eggert's dual 320M disk system to stay up under load all
weekend- hopefully we're in good enough for now shape.

0424fb537e When freeing a request, zero out the sequence number.
Define the CFG_DAGA_OFF offset as 128 bytes instead of 40- gives us
a more reasonable headroom.

When reading a config page, zero out the entire request area- not just
the length of the request. This is because we cleverly (cheezily) return
configuration data back into the allocated request area, so it's nice
to make sure we start with a clean area to write on.

7812d86f03 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

6fb3d70418 For reasons now lost in historical fog, the bounds_check_with_label()
function were put in i386/i386/machdep.c from where it has been
cut and pasted to other architectures with only minor corruption.

Disklabel is really a MI format in many ways, at least it certainly
is when you operate on struct disklabel.

Put bounds_check_with_label() back in subr_disklabel.c where it belongs.

e485b64b08 Add ability to dump stacktraces on kernel panics when DDB is compiled into

valuable panic messages off of the screen.  This option can be turned on
by the DDB_TRACE kernel option as well as the debug.trace_on_panic sysctl.

Also, fix the DDB_UNATTENDED option to use its own header instead of
abusing opt_ddb.h.  This way turning that one option on or off doesn't
force you to recompile all of ddb.

c79408a059 Implement db_print_backtrace() if DDB is compiled into the kernel. This
MD function is just a wrapper around db_stack_trace_cmd() that prints out
a backtrace of curthread.  Currently, this function is only implemented
on i386 and alpha (and the alpha version isn't quite tested yet, will do
that in a bit).  Other changes:

- For i386, fix a bug in the raw frame address case.  The eip we extract
  from the passed in frame address does not match the frame we received.
  Thus, instead of printing a bogus frame with the wrong eip, go ahead
  and advance frame down to the same frame as the eip we are using.
- For alpha, attempt to add a way of doing a raw trace for alpha.  Instead
  of passing a frame address in 'addr', pass in a pointer to a structure
  containing PC and KSP and use those to start the backtrace.  The alpha
  db_print_backtrace() uses asm to read in the current PC and KSP values
  into such a request.

37ee08bcab From Christian Zander:
This patch addresses a bug that can cause a GPF in the kernel - if a
process makes use of i386_set_ldt to install a LDT entry, then loads
a corresponding segment descriptor into %gs, forks, and if the child
execs.

In this scenario, setregs executes user_ldt_free and then determines
how to reset the %gs register:

    /* reset %gs as well */
    if (pcb == curpcb)
        load_gs(_udatasel);
    else
        pcb->pcb_gs = _udatasel;

This is insufficient in the fork/exec case, since pcb will be equal
to curpcb when the child execs; load_gs will reset %gs to _udatasel
but it doesn't reset pcb->pcb_gs; upon return from the system call,
cpu_switch_load_gs will thus attempt to restore %gs from pcb->pcb_gs
and trigger a GPF since all LDT entries have already been cleared.

The fix is to always reset pcb->pcb_gs to _udatasel.

to VOP_FSYNC(), implement rwatson's suggestion to lock the file vnode

also locked the file vnode right away in their link methods.  Remove the
locking and and unlocking from the leaf filesystem link methods.

4a3276d4a4 While well intentionned the check to see it there is a packet

The check itself didn't take into account the fact that the

defined specifically for cases where the caller knows what it wants.
Rather than fix the check I'm removing it as phk suggested.

6d5dec35b7 Add the rest of the kernel support for the sem_ API in kern/uipc_sem.c.
Option 'P1003_1B_SEMAPHORES' to compile them in, or load the "sem" module
to activate them.

Have kern/makesyscalls.sh emit an include for sys/_semaphore.h into sysproto.h
to pull in the typedef for semid_t.

Add the syscalls to the syscall table as module stubs.

efaa658806 Bring in my implementation of kernel support for posix realtime semaphores
that are shareable between processes.

There will be a cleanup shortly along with the necessary changes made to
libc, libc_r, libpthread as well as the hooks into sys/conf and sys/modules.

bd395ae8f6 style nit: unsigned -> u_int in the kernel, particularly to
stay consistent in this file, and keep m_length() and m_fixhdr()
consistent with their prototypes in mbuf.h

2201e1b039 Optimize the way we call BPF a tiny bit: If we chop the ether-header off
ourselves, call bpf before we do so, rather than re-construct the entire
thing afterwards.

f0e2422b1b Use m_length() instead of home-rolled.
In bpf_mtap(), if the entire packet is in one mbuf, call bpf_tap()
instead since it is a tad faster.

This should allow read only access to file which is already opened on server.
