4bfa972e11 Rework jumbo frame handling. QAC confirmed that the controller
requires 8 bytes alignment on RX buffer.  Given that non-jumbo
frame works on any alignments I guess this DMA limitation for RX
buffer could be jumbo frame specific one.  Also I'm not sure
whether this DMA limitation is related with 64bit DMA.  Previously
age(4) disabled 64bit DMA addressing due to silent data corruption.
So we may need more testing on re-enabling 64bit DMA in future.

While I'm here, change mbuf chaining algorithm to use fixed sized
buffer and force software checksum if controller reports length
error. According to QAC, RFD is not updated at all for jumbo frame
so it works just like alc(4) controllers.  This change also added
alignment fixup for strict alignment architectures.  Because I'm
not aware of any non-x86 machines that use age(4) controllers it's
just for completeness at this moment.

Wit this change, jumbo frame should work with age(4).

897e2fb505 Allow the unwind functions int libgcc_s to interact correctly with libthr.
_Unwind_ForcedUnwind in libgcc_s takes as one of it's parameters a stop
function to tell it when to stop unwinding. One of the stop function's
parameters is a _Unwind_Exception_Class. On most architectures this is an
int64_t, however on ARM EABI the gcc developers have made this a char array
with 8 items. While both of these take the same space they are passed into
the stop function differently, an int64_t is passed in in registers r2 and
r3, while the char[8] is passed in as a pointer to the first item in
register r2.

Because libthr expects the value to be an int64_t we would get incorrect
results when it passes a function that take an int64_t but libgcc passes in
a pointer to a char array including crashing.

The fix is to update libgcc_s to make it pass an int64_t to the stop
function and to libstdc++ as it expects _Unwind_Exception_Class to be an
array.

a191badca4 Extend GDB to check the value in the .note.tag section along with the
.note.ABI-tag section.

This helps on ARM EABI where the OS/ABI field is zero. It would be better
to use the NOTES program header however this would require a more invasive
change.

d70abf9adc crunchide(1): support non-custom elf object layout
The crunchide utility presumes the last 3 chunks of an ELF object
layout are section headers, symbol table, and then string table.
However, this is  not specified in the ELF standards, and linkers
may generate different layouts when doing partial linking (-r).

This change is required to build FreeBSD with mclinker or the
gold linker.

2d2c37fb59 zfs: fix, improve and re-organize page_lookup and page_unlock
Now they are split into two pairs: page_hold/page_unhold for mappedread
and page_busy/page_unbusy for update_pages.

For mappedread we simply hold a page that is to be used as a source if it
is resident and valid (and not busy).  This is sufficient since we are
only doing page -> user buffer copying.  There is no page <-> backing
storage I/O involved.

update_pages is now better split to properly handle the putpages case
(page -> arc) and the regular write case (arc -> page).

For the latter we use complete protocol of marking an object with
paging-in-progress and marking a page with io_start (busy count).
Also, in this case we remove the write bit from all page mappings and
clear dirty bits of the pages, the former is needed to ensure that the
latter does the right thing.
Additionally we update a page if it is cached instead of just freeing it
as was done before.  This needs to be verified.

A minor detail: ZFS-backed pages should always be either fully valid
or fully invalid.  Assert this and use simpler API that does not deal
with sub-page blocks.

1858329b43 For UFS2 i_blocks is unsigned. The current "sanity" check that it
has gone below zero after the blocks in its inode are freed is a
no-op which the compiler fails to warn about because of the use of
the DIP macro. Change the sanity check to compare the number of
blocks being freed against the value i_blocks. If the number of
blocks being freed exceeds i_blocks, just set i_blocks to zero.

6fa139d56e sh: Expand here documents in the current process.
Expand here documents at the same point other redirections are expanded but
use a non-fork subshell environment (like simple command substitutions) for
compatibility. Substitition errors result in an empty here document like
before.

As a result, a fork is avoided for short (<4K) expanded here documents.

Unexpanded here documents (with quoted end marker after <<) are not affected
by this change. They already only forked when >4K.

Side effects:
* Order of expansion is slightly different.
* Slow expansions are not executed in parallel with the redirected command.
* A non-fork subshell environment is subtly different from a forked process.

08016a40d7 allow for large KTR_ENTRIES values by allocating ktr_buf using malloc(9)
Only during very early boot, before malloc(9) is functional (SI_SUB_KMEM),
the static ktr_buf_init is used.  Size of the static buffer is determined
by a new kernel option KTR_BOOT_ENTRIES.  Its default value is 1024.

This commit builds on top of r243046.

c2bbbcc61a Another overhaul of the CPSW driver for BeagleBone
Major changes:
  * Finally tracked down the flow control setting that
    seems to have been causing TX stalls and watchdog timeouts
  * RX and TX paths now share a lot more code
  * TX interrupt is no longer used; we instead GC finished
    tx queue entries at the bottom of the start routine.
  * TX start now queues fragmented packets directly; it only
    invokes defrag() for occasional very fragmented packets.
  * "sysctl dev.cpsw" dumps controller statistics and queue counts
  * Host Error Interrupt will give extensive debugging information
    if the controller chokes on the queued data.

Dont use/link ARCMT, StaticAnalyzer and Rewriter to clang when the user

  StaticAnalyzer when it's disabled.

  Without all those three, the clang binary shrinks (x86_64) from ~36MB
  to ~32MB (unstripped).

To disable these clang components, and get a smaller clang binary built
and installed, set WITHOUT_CLANG_FULL in src.conf(5).  During the
initial stages of buildworld, those extra components are already
disabled automatically, to save some build time.
