For efficiency, as other kernel components, memory cgroup uses some optimization
to avoid unnecessary cacheline false sharing. usage_in_bytes is affected by the
method and doesn't show 'exact' value of memory(and swap) usage, it's an fuzz
value for efficient access. (Of course, when necessary, it's synchronized.)

Xeon support
------------
Some Xeon processors have real max1617, adm1021, or compatible chips
within them, with two temperature sensors.
Netburst-based Xeon support
---------------------------
Other Xeons have chips with only one sensor.
Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
within them, with two temperature sensors. Other Xeon processors of this
era (with 400 MHz FSB) had chips with only one temperature sensor.
If you have a Xeon, and the adm1021 module loads, and both temperatures
appear valid, then things are good.
If you have such an old Xeon, and you get two valid temperatures when
loading the adm1021 module, then things are good.
If the adm1021 module doesn't load, you should try this:
modprobe adm1021 force_adm1021=BUS,ADDRESS
ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
If nothing happens when loading the adm1021 module, and you are certain
that your specific Xeon processor model includes compatible sensors, you
will have to explicitly instantiate the sensor chips from user-space. See
method 4 in Documentation/i2c/instantiating-devices. Possible slave
addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
only temp2 will be correct and temp1 will have to be ignored.
If you have dual Xeons you may have appear to have two separate
adm1021-compatible chips, or two single-temperature sensors, at distinct
addresses.
Previous generations of the Xeon processor (based on Pentium II/III)
didn't have these sensors. Next generations of Xeon processors (533 MHz
FSB and faster) lost them, until the Core-based generation which
introduced integrated digital thermal sensors. These are supported by
the coretemp driver.

This driver has basic support for SMBus alert. When an alert is received,
the status register is read and the faulty temperature channel is logged.
The Analog Devices chips (ADM1032 and ADT7461) do not implement the SMBus
alert protocol properly so additional care is needed: the ALERT output is
disabled when an alert is received, and is re-enabled only when the alarm
is gone. Otherwise the chip would block alerts from other chips in the bus
as long as the alarm is active.

* Unless work items are expected to consume a huge amount of CPU
cycles, using a bound wq is usually beneficial due to the increased
level of locality in wq operations and work item execution.
7. Debugging
Because the work functions are executed by generic worker threads
there are a few tricks needed to shed some light on misbehaving
workqueue users.
Worker threads show up in the process list as:
root 5671 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/0:1]
root 5672 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/1:2]
root 5673 0.0 0.0 0 0 ? S 12:12 0:00 [kworker/0:0]
root 5674 0.0 0.0 0 0 ? S 12:13 0:00 [kworker/1:0]
If kworkers are going crazy (using too much cpu), there are two types
of possible problems:
1. Something beeing scheduled in rapid succession
2. A single work item that consumes lots of cpu cycles
The first one can be tracked using tracing:
$ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
$ cat /sys/kernel/debug/tracing/trace_pipe > out.txt
(wait a few secs)
^C
If something is busy looping on work queueing, it would be dominating
the output and the offender can be determined with the work item
function.
For the second type of problems it should be possible to just check
the stack trace of the offending worker thread.
$ cat /proc/THE_OFFENDING_KWORKER/stack
The work item's function should be trivially visible in the stack
trace.

* Date: Fri Dec 17 16:58:28 2010 -0800
*
* x86-64, mm: Put early page table high
*
* at some point init_memory_mapping is going to reach the pagetable pages
* area and map those pages too (mapping them as normal memory that falls
* in the range of addresses passed to init_memory_mapping as argument).
* Some of those pages are already pagetable pages (they are in the range
* pgt_buf_start-pgt_buf_end) therefore they are going to be mapped RO and
* everything is fine.
* Some of these pages are not pagetable pages yet (they fall in the range
* pgt_buf_end-pgt_buf_top; for example the page at pgt_buf_end) so they
* are going to be mapped RW. When these pages become pagetable pages and
* are hooked into the pagetable, xen will find that the guest has already
* a RW mapping of them somewhere and fail the operation.
* The reason Xen requires pagetables to be RO is that the hypervisor needs
* to verify that the pagetables are valid before using them. The validation
* operations are called "pinning".
*
* In order to fix the issue we mark all the pages in the entire range
* pgt_buf_start-pgt_buf_top as RO, however when the pagetable allocation
* is completed only the range pgt_buf_start-pgt_buf_end is reserved by
* init_memory_mapping. Hence the kernel is going to crash as soon as one
* of the pages in the range pgt_buf_end-pgt_buf_top is reused (b/c those
* ranges are RO).
*
* For this reason, 'mark_rw_past_pgt' is introduced which is called _after_
* the init_memory_mapping has completed (in a perfect world we would
* call this function from init_memory_mapping, but lets ignore that).
*
* Because we are called _after_ init_memory_mapping the pgt_buf_[start,
* end,top] have all changed to new values (b/c init_memory_mapping
* is called and setting up another new page-table). Hence, the first time
* we enter this function, we save away the pgt_buf_start value and update
* the pgt_buf_[end,top].
*
* When we detect that the "old" pgt_buf_start through pgt_buf_end
* PFNs have been reserved (so memblock_x86_reserve_range has been called),
* we immediately set out to RW the "old" pgt_buf_end through pgt_buf_top.
*
* And then we update those "old" pgt_buf_[end|top] with the new ones
* so that we can redo this on the next pagetable.
