paper trail now, this patch is similar to one posted for one of the
preliminary versions of a new armv6 port. I took them and made them
more generic. Option not enabled by default since each board/port has
to provide its own eputc, and possibly do other things as well...
Use the bitwise negation instead of bogus boolean negation and move
the flag manipulation with the assignment.
Fix some grammatical errors introduced in the same change.

pim_input() properly.
While here, remove extra variable and incorrect condition
before m_pullup().

a timeout value of a single tick is given. With FreeBSD-10 and newer
the current system time is used as a starting point, and the minimum
callout time of a single tick will be guaranteed. This patch mostly
affect the DMA delay timeouts, which are typically in the range from
0.125 to 2ms.

via a software interrupt.
This is safe to do because the logical processor is already cognizant of the
NMI and further NMIs are blocked until the host's NMI handler executes "iret".
r260545 cleared the inode flags to fix corruption problems but
we still need to pass some EXT4 flags for the ext4 read-only
mode. None of these attributes has an equivalent in FreeBSD and
are uninteresting for the system utilities so they should be
innaccessible in ext2_getattrib().
Note: we also use EXT4_HUGE_FILE but we use it directly from the
dinode structure so it is not necessary to translate it,

This is the first step needed to get the snapper codec working on those
machines.
The second step is to enable the corresponding I2S device and its clock.
Tested on machines where the snapper codec was already working, a G4 PowerBook
and a PowerMac9,1 with a Shasta based macio.
The PowerMac7,2/7,3 with a K2 based macio can now also play sound.

- Store the length of each read-only VPD value since not all values are
guaranteed to be ASCII values (though most are).
- Add a new pciio ioctl to fetch VPD for a single PCI device. The values
are returned as a list of variable length records, one for the device
name and each keyword.
- Add a new -V flag to pciconf's list mode which displays VPD data for
each device.

fence. Under system load, the CPU has been found to change the order
by which the stores are made visible. When the tag is made visible
before the other TLB values, other CPUs may use the invalid TLB values
and do bad things.
While here (i.e. not a fix) don't return errors from pmap_remove_vhpt()
to callers of pmap_remove_pte(). Those callers don't check the return
value and as such don't do what is needed to keep a consistent state.
More importantly, pmap_remove_vhpt() can't really have an error without
it indicating something unintended. Using KASSERT is therefore better.

console, it calls the grab functions. These functions should turn off
the RX interrupts, and any others that interfere. This makes mountroot
prompt work again. If there's more generalized need other than
prompting, many of these routines should be expanded to do those new
things.
Should have been part of r260889, but waasn't due to command line typo.

* Set ia address/mask values BEFORE attaching to address lists.
Inet6 address assignment is not atomic, so the simplest way to
do this atomically is to fill in ia before attach.
* Validate irfa->ia_addr field before use (we permit ANY sockaddr in old code).
* Do some renamings:
in6_ifinit -> in6_notify_ifa (interaction with other subsystems is here)
in6_setup_ifa -> in6_broadcast_ifa (LLE/Multicast/DaD code)
in6_ifaddloop -> nd6_add_ifa_lle
in6_ifremloop -> nd6_rem_ifa_lle
* Split working with LLE and route announce code for last two.
Add temporary in6_newaddrmsg() function to mimic current rtsock behaviour.
* Call device SIOCSIFADDR handler IFF we're adding first address.
In IPv4 we have to call it on every address change since ARP record
is installed by arp_ifinit() which is called by given handler.
IPv6 stack, on the opposite is responsible to call nd6_add_ifa_lle() so
there is no reason to call SIOCSIFADDR often.

VGA hardware at the standard/legacy VGA I/O port and memory I/O
addresses. This can cause machine checks if the H/W does not have

of a syncache connection, copy it into the inp_flowid field.
Without this, an incoming TCP connection won't have an inp_flowid marked
until some data comes in, and this means that things like the per-CPU
TCP timer option will choose a different CPU for the timer work.
(It also means that if one grabbed the flowid via an ioctl from userland,
it won't be available until some data has been received.)

callback providers. link_init_sdl() function can be used to
fill most of the parameters. Use caller stack instead of
allocation / freing memory for each request. Do not drop support
for extra-long (probably non-existing) link-layer protocols by
introducing link_alloc_sdl() (used by if_resolvemulti() callback)
and link_free_sdl() (used by caller).
Since this change breaks KBI, MFC requires slightly different approach
(link_init_sdl() auto-allocating buffer if necessary to handle cases
with unmodified if_resolvemulti() callers).

the Guest Interruptibility-state field. However, there isn't any way to
figure out which processors have this requirement.
So, inject a pending NMI only if NMI_BLOCKING, MOVSS_BLOCKING, STI_BLOCKING
are all clear. If any of these bits are set then enable "NMI window exiting"
and inject the NMI in the VM-exit handler.
1. Be consistent in the style of "act_delta" manipulations between the
inactive and active queue scans.
2. Explicitly compare to zero.
3. The deactivation of a page is based is based on its recent history
and not just the current call to vm_pageout_scan(). The variable
"act_delta" represents the current state of the page, and not its
history. Avoid possible confusion by not (ab)using "act_delta" for
the making the deactivation decision.
