a34292623f Fix regression introduced in r196712 - the 'name' string needs
to be rewritten for each file we want to check ACL on.  Without
this change, ls(1) would check only the ACL on the first file
to list.

8d3635c4db Fix some bugs related to adaptive spinning:
In the lockmgr support:
- GIANT_RESTORE() is just called when the sleep finishes, so the current
  code can ends up into a giant unlock problem.  Fix it by appropriately
  call GIANT_RESTORE() when needed.  Note that this is not exactly ideal
  because for any interation of the adaptive spinning we drop and restore
  Giant, but the overhead should be not a factor.
- In the lock held in exclusive mode case, after the adaptive spinning is
  brought to completition, we should just retry to acquire the lock
  instead to fallthrough. Fix that.
- Fix a style nit

In the sx support:
- Call GIANT_SAVE() before than looping. This saves some overhead because
  in the current code GIANT_SAVE() is called several times.

c9e8817902 - Work around ACPI mode transition problem for recent NVIDIA 9400M chipset
based Intel Macs.  Since r189055, these platforms started freezing when
ACPI is being initialized for unknown reason.  For these platforms, we just
use the old PAT layout.  Note this change is not enough to boot fully on
these platforms because of other problems but it makes debugging possible.
Note MacBook5,2 may be affected as well but it was not added here because
of lack of hardware to test.
- Initialize PAT MSR fully instead of reading and modifying it for safety.

2689ba2720 Add NFSv4 ACL support to cp(1) and fix a few memory leaks.
Note that this changes error reporting behaviour somewhat - before,
no error was reported if ACL couldn't be copied because the target
filesystem doesn't support ACLs.  Now, it will be reported - of course,
only if there actually is an ACL to copy.

of these counters relate to operations on the L2 cache.

cc7e9d4325 In case an upper layer protocol tries to send a packet but the
L2 code does not have the ethernet address for the destination
within the broadcast domain in the table, we remember the
original mbuf in `la_hold' in arpresolve() and send out a
different packet with an arp request.
In case there will be more upper layer packets to send we will
free an earlier one held in `la_hold' and queue the new one.

Once we get a packet in, with which we can perfect our arp table
entry we send out the original 'on hold' packet, should there
be any.
Rather than continuing to process the packet that we received,
we returned without freeing the packet that came in, which
basically means that we leaked an mbuf for every arp request
we sent.

Rather than freeing the received packet and returning, continue
to process the incoming arp packet as well.
This should (a) improve some setups, also proxy-arp, in case it was an
incoming arp request and (b) resembles the behaviour FreeBSD had
from day 1, which alignes with RFC826 "Packet reception" (merge case).

Rename 'm0' to 'hold' to make the code more understandable as
well as diffable to earlier versions more easily.

Handle the link-layer entry 'la' lock comepletely in the block
where needed and release it as early as possible, rather than
holding it longer, down to the end of the function.

8a945d109c Reintroduce the r196640, after fixing the problem with my testing.
Remove the altkstacks, instead instantiate threads with kernel stack
allocated with the right size from the start. For the thread that has
kernel stack cached, verify that requested stack size is equial to the
actual, and reallocate the stack if sizes differ [1].

This fixes the bug introduced by r173361 that was committed several days
after r173004 and consisted of kthread_add(9) ignoring the non-default
kernel stack size.

Also, r173361 removed the caching of the kernel stacks for a non-first
thread in the process. Introduce separate kernel stack cache that keeps
some limited amount of preallocated kernel stacks to lower the latency
of thread allocation. Add vm_lowmem handler to prune the cache on
low memory condition. This way, system with reasonable amount of the
threads get lower latency of thread creation, while still not exhausting
significant portion of KVA for unused kstacks.

using descriptor size would make intention clearer.
Previously the size of rx descriptor was not power of 2 so it

75e66e421a Improve pmap_change_attr() so that it is able to demote a large (2/4MB)
page into 4KB pages as needed.  This should be fairly rare in practice
on i386.  This includes merging the following changes from the amd64 pmap:
180430, 180485, 180845, 181043, 181077, and 196318.
- Add basic support for changing attributes on PDEs to pmap_change_attr()
  similar to the support in the initial version of pmap_change_attr() on
  amd64 including inlines for pmap_pde_attr() and pmap_pte_attr().
- Extend pmap_demote_pde() to include the ability to instantiate a new page
  table page where none existed before.
- Enhance pmap_change_attr().  Use pmap_demote_pde() to demote a 2/4MB page
  mapping to 4KB page mappings when the specified attribute change only
  applies to a portion of the 2/4MB page.  Previously, in such cases,
  pmap_change_attr() gave up and returned an error.
- Correct a critical accounting error in pmap_demote_pde().

a505c2c72c Make the mnt_writeopcount and mnt_secondary_writes counters,
used by the suspension code, not greater then mnt_ref reference
counter value. Increment mnt_ref together with write counter
in vn_start_write()/ vn_start_secondary_write(), releasing in
vn_finished_write/vn_finished_secondary_write().

Since r186197, unmount code requires that no writers occured after all
references are expired. We still could get write counter incremented
for freed or reused struct mount, but it seems to be innocent, since
corresponding vnode should be referenced and reclaimed then.
