It was possible for an interrupt or other preemptive action to
come along during a pmap operation and issue its own pmap operation,
potentially leading to races which corrupt the pmap.
This case was tested an could actually occur, though the damage (if any)
is unknown. x86_64 machines have had a long standing and difficult to
reproduce bug where a program would sometimes seg-fault for no reason.
It is unknown whether this fixes the bug or not.

in the pm_active field.
Check for the interlock in swtch.s when switching into threads
and print a nice warning if it occurs.
It was possible for one cpu to initiate a pmap modifying operation
while another switches into a thread using the pmap the first cpu
was in the middle of modifying. The case is extremely rare but can
occur if the cpu doing the modifying operation receives a SMI
interrupt, stalling it long enough for the other cpu to switch
into the thread and resume running in userspace.
* pmap_protect() assumed no races when clearing PG_RW and PG_M due
to the pmap_inval operations it runs. This should in fact be
true with the above fixes. However, the rest of the pmap code
uses atomic operations so adjust pmap_protect() to also use atomic

kernel - Update swapcache manual page
* The manual page is still a work in progress but I'm pushing in everything
I learn about SSDs into it as I learn them.
At least insofar as the Intel X25-V 40G SSD goes the vendor-specified
40TB write endurance limit appears to assume high write magnifications
and significant inefficiencies in write patterns. The theoretical
write endurance limit for this SSD with static wear leveling is 400TB.
My expectation is a practical endurance somewhere between 150-250TB
when configuring 32G of swap on the 40G X25-V. The manual page will be
updated as I get better numbers from testing.
* Specify that disklabel64 should be used when labeling a SSD, so
the partitions are properly aligned. Kernels as of id
4921cba1f6
(late 2.5.x) will align the partition base for virgin disklabel64
labels to a 1MB boundary.
MLC flash uses 128K write blocks, SLC uses 64K. Swapcache will write
in 64K clusters but also tends to issue multiple linear writes, leading
to fairly optimal SSD operation.

kernel - disklabel64 - Increase partition start alignment to 1 megabyte.
* Someone suggested that instead of using a 32K alignment we use a larger
alignment. I forgot who suggested it but after thinking about it a bit
and messing around with swapcache on a SSD I decided it was a good idea.
SSDs using MLC flash have a physical block size of 128K. SLC flash has
a physical block size of 64K. Most typical cluster operations in
DragonFly are 64K to 128K but clustered writes are often linear on disk
leading to larger linear writes from the point of view of the physical
drive's write cache.
swapcache and swap operation tends to have even larger write linearities
and write amplification effects on SSDs can be reduced to better than 1:2
(verses the 1:10 the vendor typically assumes).
* Virgin disklabel64's layed down by the kernel will now align the
start of the partition space to 1MB (1024 * 1024). In for a penny,
in for a pound.
* Adjust the manual page and note the benefits of using a larger alignment,
particularly when swapcache is used with SSDs.

HAMMER VFS - Reduce stalls during bulk file operations
* Track modifying inode operations on a per-PID basis (loosely) and
call hammer_inode_wait_reclaims() earlier for those pids.
The algorithm selects a wait point based on the process's perceived
contribution to the inode load. The greater the contribution, the
more readily we stall the process in order to wait for related reclaims
to process.
Processes with lower loads have higher reclaim points and do not stall
as readily as they did before.

this in there but it was creating an excessive number of unnecessary
stalls, so if any problems crop up I'll have to find another way to deal

evtranalyze: add summary command and refactor interval code
Allow the user to specify a time interval in miliseconds. Coupled
with the summary command, this makes it easy to select a subset of
the events for the svg command.
Also fix the svg code to not assume there are always 5 threads
with activity.
Add a new option to the svg command to write to a different path
(the default remains "output.svg").
