Cherry-picked from upstream:
https://git.savannah.gnu.org/gitweb/?p=config.git;a=commit;h=1c4398015583eb77bc043234f5734be055e64bea
Everything except external/apache2/llvm/dist/llvm/cmake/config.guess
is patched, which is under vendor tag and cannot be modified. I expect
that this file is not actually used as we use hand-crafted version of
configure script instead of cmake for building LLVM.
Note that external/apache2/llvm/autoconf/autoconf/config.guess has
already been committed on Oct. 20, but commit message disappeared as
cvs aborted due to "permission denied" when trying to modify the file
mentioned above. Sorry for confusing you.
Also note that GMP uses its own config.guess Patch for
external/lgpl3/gmp/dist/config.guess is provided by ryo@. Thanks!
At first, it seems "IXGBE_WRITE_REG(hw, IXGBE_EIMC, IXGBE_EIMC_OTHER)"
cannot stop interrupts, because 31th bit is reserved for 82598, 82599,
X540 and X550. So, the current following design
(1) ixgbe_msix_admin() disables interrupts
(2) ixgbe_msix_admin() calls workqueue_enqueue() for ixgbe_handle_admin()
(3) ixgbe_handle_admin() does interrupt processing
(4) after ixgbe_handle_admin() has done all interrupt processings,
ixgbe_handle_admin() enables interrupts
does not work correctly, that is, interrupts can be lost while
ixgbe_handle_admin() is running.
To fix that, add new spin mutex(adapter->admmin_mtx) which protects
atomically the following two members.
- adapter->admin_pending
- adapter->task_requests
The unnecessary "IXGBE_WRITE_REG(hw, IXGBE_EIMC, IXGBE_EIMC_OTHER)"
code will be removed later.
Reviewed and tested by hikaru@n.o and msaitoh@n.o, thanks.
the existing SS_ASYNC. SS_ASYNC was already vestigial at that point,
having been superceded by SB_ASYNC, however the SS_ASYNC flag is still
set and cleared, unlessly because it is never checked.
Fix this conflict by removing SS_ASYNC and its vestigial uses.
Initialization and destruction of the fields is independent from the
other fields. Therefore use declaration order, which allows to quickly
see whether a field was forgotten.
While here, add comments that in cleanup mode, not all memory is freed.
The variables of a node and the suffix survive right now.
In CLEANUP mode, Var_Init depends on Targ_Init since the variable scopes
are implemented as GNodes.
By the way, since 1999-09-15 variables are no longer stored in lists but
in hash tables.
This function is a classical constructor function, and if it weren't for
CLEANUP mode, it would have no dependencies on anything else besides the
memory allocator. Therefore it doesn't really matter which module
defines this function, and there is no need for the "Targ" to be part of
the function name.

Tested by aarch64eb with I210-T1 on ROCKPro64.
Thanks msaitoh for discussion!
XXX
pullup to netbsd-9 and netbsd-8
Fix some mistakes in comments.
Improve some comments to be easier understandable.
Inline variables that are irrelevant for the test at hand (RUN,
MAKE_CMD).
Remove references to functions and constants that have since been removed
or renamed.
The main changes are in the comments, which have been shortened and
corrected.
Some local variables changed their names.
In ParseErrorInternal, the scope of va_start is now narrower.
In ParseDoDependency, the type of tOp has been fixed.
ParseGetLine doesn't take flags anymore but instead a parsing mode.
Previously, the flags had not been combined anyway.
At the beginning of Parse_File, fatals is already guaranteed to be 0, and
even if not, it would be wrong to just discard the fatal errors.
