This brings the default configurations (drivers, net80211 settings, etc) and some
of the shared configuration into std.AR_MIPS_BASE. I haven't yet moved the
-current settings (witness, memguard, etc) into it.
This should simplify building a lot of the same test images for my MIPS AP board
development and testing.
This is a work in progress; it's not designed to be perfect!
iflib - Handle out of order packet delivery from hardware in support of LRO
Out of order updates to rxd's is fixed in r315217. However, it is not
completely fixed. While refilling the buffers, iflib is not considering
the out of order descriptors. Hence, it is refilling sequentially.
"idx" variable in _iflib_fl_refill routine is incremented sequentially.
By doing refilling sequentially, it will override the SGEs that
are *IN USE* by other connections. Fix is to maintain a bitmap of
rx descriptors and differentiate the used one with unused one and
refill only at the unused indices. This patch also fixes a
few bugs in bnxt, related to the same feature.

Description:
There was a misunderstanding about the enforcement details of the "Read-only"
flag introduced for SMB/CIFS compatibility, way back in 2007 in the Sun PSARC
2007/315 case.
The original authors thought enforcement of the READONLY flag should work
similarly as the IMMUTABLE flag. Unfortunately, that enforcement is
incompatible with the expectations of Windows applications using this feature
through the SMB service. Applications assume (and the MS File System Algorithms
MS-FSA confirms they should) that an SMB client can:
(a) Open an SMB handle on a file with read/write access,
(b) Set the DOS attributes to include the READONLY flag,
(c) continue to have write access via that handle.
This access model is essentially the same as a Unix/POSIX application that
creates a file (with read/write access), uses fchmod() to change the file mode
to something not granting write access (i.e. 0444), and then continues to write
that file using the open handle it got before the mode change.
Currently, the SMB server works-around this problem in a way that will become
difficult to maintain as we implement support for SMB3 persistent handles, so
SMB depends on this fix.
I've written a test program that can be used to demonstrate this problem, and
added it to zfs-tests (tests/functional/acl/cifs/cifs_attr_004_pos).
It currently fails, but will pass when this problem fixed.
Steps to Reproduce:
Run the test program on a ZFS file system.
Expected Results:
Pass
Actual Results:
Fail.

All interrupts are routed to the sole CPU in that case implicitly.
This is a regression in EARLY_AP_STARTUP. Previously the 'assign_cpu'

it's value both meant that interrupts could be assigned and that
there was more than one CPU.

Some blocks depend on the platform clock rather than the system clock.
The System clock is derived from the platform clock as one-half the

Such requests would previously mark the entire page as valid, which was
incorrect since nothing guaranteed that the page's contents had been

entire page is marked dirty, rather than only a subrange. There is no

they are masked/unmasked using separate registers' sets

additional allocation overhead. Previously, blst_meta_alloc() updated the
hint after every successful allocation. However, these "eager" hint
updates are of no actual benefit if, instead, the "lazy" hint update at
the start of blst_meta_alloc() is generalized to handle all cases where
the number of available blocks is less than the requested allocation.
Previously, the lazy hint update at the start of blst_meta_alloc() only
handled the ALL-FULL case. (I would also note that this change provides
consistency between blist_alloc() and blist_fill() in that their hint
maintenance is now entirely lazy.)
Eliminate unnecessary checks for terminators in blst_meta_alloc() and
blst_meta_fill() when handling ALL-FREE meta nodes.
Eliminate the field "bl_free" from struct blist. It is redundant. Unless
the entire radix tree is a single leaf, the count of free blocks is stored
in the root node. Instead, provide a function blist_avail() for obtaining
the number of free blocks.
In blst_meta_alloc(), perform a sanity check on the allocation once rather
than repeating it in a loop over the meta node's children.
In blst_leaf_fill(), use the optimized bitcount*() function instead of a
loop to count the blocks being allocated.
Add or improve several comments.
Address some nearby style errors.

struct thread.
For all architectures, the syscall trap handlers have to allocate the
structure on the stack. The structure takes 88 bytes on 64bit arches
which is not negligible. Also, it cannot be easily found by other
code, which e.g. caused duplication of some members of the structure
to struct thread already. The change removes td_dbg_sc_code and
td_dbg_sc_nargs which were directly copied from syscall_args.
The structure is put into the copied on fork part of the struct thread
to make the syscall arguments information correct in the child after
fork.
This move will also allow several more uses shortly.
