f080384c8f sfxge: fix overflow queue freeze
If TxQ lock is obtained, deferred packet list shold be serviced even if
the packet addition fails because of overflow.

Without the patch freeze happens if:
 - queue is not blocked (i.e. completion does not trigger unblock and service)
 - put-list overflow (1024 entries)
 - sfxge_tx_packet_add() acquires TxQ lock just as it is released it in
   sfxge_tx_qdpl_service() on the second CPU but before pending check
 - sfxge_tx_packet_add() swizzles put-list to get-list, fails because of
   non-tcp get-list overflow and returns without packet list service
 - sfxge_tx_qdpl_service() on the second CPU checks that there are no
   pending packets in the put-list and returns

Other possible solution is to guaranee that maximum length of the put-list
is less than maximum length of any get-list.

45f8d9f9a8 An ARM kernel can be loaded at any 2MB boundary, make ubldr aware of that.
Previously, ubldr would use the virtual addresses in the elf headers by
masking off the high bits and assuming the result was a physical address
where the kernel should be loaded.  That would sometimes discard
significant bits of the physical address, but the effects of that were
undone by archsw copy code that would find a large block of memory and
apply an offset to the source/dest copy addresses.  The result was that
things were loaded at a different physical address than requested by the
higher code layers, but that worked because other adjustments were applied
later (such as when jumping to the entry point).  Very confusing, and
somewhat fragile.

Now the archsw copy routines are just simple copies, and instead
archsw.arch_loadaddr is implemented to choose a load address.  The new
routine uses some of the code from the old offset-translation routine to
find the largest block of ram, but it excludes ubldr itself from that
range, and also excludes   If ubldr splits the largest block of ram in
two, the kernel is loaded into the bottom of whichever resulting block is
larger.

As part of eliminating ubldr itself from the ram ranges, export the heap
start/end addresses in a pair of new global variables.

This change means that the virtual addresses in the arm kernel elf headers
now have no meaning at all, except for the entry point address.  There is
an implicit assumption that the entry point is in the first text page, and
that the address in the the header can be turned into an offset by masking
it with PAGE_MASK.  In the future we can link all arm kernels at a virtual
address of 0xC0000000 with no need to use any low-order part of the
address to influence where in ram the kernel gets loaded.

b7112ead32 Clean up struct syscall_args:
1. Align to a 64-bit address so 64-bit data will be correctly aligned.
 2. Add a comment explaining why.
 3. Remove an unneeded value from the struct.

This fixes an issue where the struct may not be correctly aligned on the
stack in the syscall function. This may lead to accesing a 64-bit value
at a non 64-bit. This will raise an exception and panic the kernel.

We have been lucky where on arm and armv6 both clang and gcc correctly
align the data, even without us asking to, however, on armeb with clang to
not be the case. This tells the compiler we really do need this to be
aligned.

afd1f4a7e3 Do not set preload_addr_relocate for ARM. Apparently there was a time
when loader(8) passed physical addresses in loader metadata for arm, but
that is no longer true; all metadata has already been adjusted to vitual
addresses by loader.

I can't track down the exact revision in loader where a change from physical
to virtual metadata addresses happened.  The code involved is very twisty
and complicated.  I suspect the change was an unintended consequence of the
r247301, r247413, r248118 series of changes I made a couple years ago.

Mark Johnston
d4a115af56 Move siftr-related definitions out of tcp.d and into a separate library
which declares a dependency on siftr(4). This is necessitated by a
reference to struct pkt_node, which is defined in siftr(4): otherwise,
dtrace(1) will return an error during startup if siftr.ko is not loaded.

f65e699c36 As dtrace(1) processes D libraries under /usr/lib/dtrace, the compiler may
return an error if one of the depends_on directives in a library is not
satisfied. In this case, libdtrace is supposed to ignore the library and
carry on. However, the remainder of the library may still be buffered by
the lexer, causing libdtrace to erroneously continue processing it on the
next call to yyparse(). Fix this by explicitly flushing the input buffer
each time the compiler state is reset.

d3eacc0e47 Don't allow unmapped I/O. The pmap isn't quite up to the task. Add a
comment to this effect and switch the default. My old AT91SAM9G20
now boots, fsck's the SD card and runs w/o an issue for the first
time since a 9.1-ish stable build I did a few years ago.

Problems with unmapped I/O:
o un-page-aligned I/O requests to devices fail (notably fsck
  and newfs).
o write-back caching was totally broken. write-through caching
  needed to be enabled.
o Even page-aligned I/O requests sometimes failed for reasons
  not thoroughly investigated.

77ac67e29d Break apart the gnu_inline attribute and use "artificial" if available.
In general it is bad practice to use the gnu_inline attribute but we
will need it in special cases like FORTIFY_SOURCE. In this specific
case it is also useful to have the "artificial" attribute:

"This attribute is useful for small inline wrappers which if possible
should appear during debugging as a unit, depending on the debug info
format it will either mean marking the function as artificial or using the
caller location for all instructions within the inlined body."

This attribute appears to be currently implemented only in GCC. Use it
only in conjuntion with gnu_inline in the cases where it is available,
which is similar in spirit in how it's used in glibc.
