- Replace a magic 14 with the newly added IDC_ITID_SHIFT macro.
- Remove the global mp_boot_mid variable as it's not really necessary
and just replacing it with PCPU_GET(mid) doesn't have any impact on
performance once booted.
- Replace PCPU_GET(cpuid) with the curcpu shortcut.
- Replace hardcoded function names in panic strings etc with __func__
so they don't need to be updated when renaming the function.
- Use register_t instead of u_long for variables used to hold the
return value of intr_disable() so we don't need to apply any
knowledge about the actual width of that value here.
- Improve the wording of some comments.
- Fix several style(9) bugs.
- Use __FBSDID in identcpu.c.
- Remove #ifndef SUN4V around global cpu_impl variable; it doesn't
hurt on sun4v for now and once setPQL2() is gone sun4v can stop
sharing identcpu.c with sparc64, making the reminder of this file
also sparc64-only again. [1]

in the sun4v source in order to be able to compile the source which
is shared between sparc64 and sun4v just #include the sparc64
version here instead of duplicating it.
This is based on the approach taken by pc98 headers in order to
compile the source shared between i386 and pc98.
iommureg.h (which already began to bitrot) and iommuvar.h from the
sun4v source and adjust some of the source which is shared between
sparc64 and sun4v as appropriate.

This is only for the well known known ports (port 1-1023) for tcp and
udp only.
Changes:
- Removed "problems" comments around port 57, 77 and 87
- Removed audionews (port 114)
- Added imap3 (port 220)
- Removed yak-chat (port 258)
- Removed concert (port 786)
- Added a lot of new allocations

ignore the size of any headers that were passed with the sendfile(2)
system call. Otherwise the file sent will be truncated by the header
size if the nbytes parameter was provided. The bug doesn't show up
when either nbytes is zero, meaning send the whole file, or no header
iovec is provided.
Resolve a potential error aliasing of errors from the VM and sf_buf
parts and the protocol send parts where an error of the latter over-
writes one of the former.
Update comments.
The byte accounting bug wasn't seen in earlier because none of the popular
sendfile(2) consumers, Apache, lighttpd and our ftpd(8) use it in modes
that trigger it. The varnish HTTP proxy makes full use of it and exposed
the problem.

the correct symbol, thus causing a warning with GCC 4.2.0. Committed
into the vendor branch since this is already in the csup repository.

scheme allowed for 1024 PTE pages, each containing 256 PTEs.
This yielded 2GB of KVA. This is not enough to boot a kernel
on a 16GB box and in general too low for a 64-bit machine.
By adding a level of indirection we now have 1024 2nd-level
directory pages, each capable of supporting 2GB of KVA. This
brings the grand total to 2TB of KVA.
Fix the flags argument: M_WAITOK is not a valid flag. Its presence
leaves the indication that contigmalloc(9) will not return a NULL
pointer.
The use of contigmalloc(9) in this place is probably not a good idea
given the constraints. It's probably better to lift the constraints
and instead add a permanent mapping to the ITR. It's possible that
the first 256MB of memory is exhausted when we get here.
This fixes a kernel panic on a 16GB rx3600.
of each port and any further packets are blocked, when the all the marker frames
have been returned to us from the remote network device then we can be sure
that all interface queues are empty.
This is needed when a port is added or removed from the aggregation since it
will affect the hash based distribution, if the queues are not empty then a
packet from an existing connection may be placed on a different interface and
arrive out of order. This was previously achieved by suppressing transmission for
1 second, now that there is an active feedback this timeout as been increased
to 3 seconds and used as a fallback.
