Move a long comment from lib/crc32.c to Documentation/crc32.txt where it
will more likely get read.
Edited the resulting document to add an explanation of the slicing-by-n
algorithm.

SD/MMC cards tend to support an erase operation. In addition, eMMC v4.4
cards can support secure erase, trim and secure trim operations that are
all variants of the basic erase command.
SD/MMC device attributes "erase_size" and "preferred_erase_size" have been
added.
"erase_size" is the minimum size, in bytes, of an erase operation. For
MMC, "erase_size" is the erase group size reported by the card. Note that
"erase_size" does not apply to trim or secure trim operations where the
minimum size is always one 512 byte sector. For SD, "erase_size" is 512
if the card is block-addressed, 0 otherwise.
SD/MMC cards can erase an arbitrarily large area up to and
including the whole card. When erasing a large area it may
be desirable to do it in smaller chunks for three reasons:
1. A single erase command will make all other I/O on the card
wait. This is not a problem if the whole card is being erased, but
erasing one partition will make I/O for another partition on the
same card wait for the duration of the erase - which could be a
several minutes.
2. To be able to inform the user of erase progress.
3. The erase timeout becomes too large to be very useful.
Because the erase timeout contains a margin which is multiplied by
the size of the erase area, the value can end up being several
minutes for large areas.
"erase_size" is not the most efficient unit to erase (especially for SD
where it is just one sector), hence "preferred_erase_size" provides a good
chunk size for erasing large areas.
For MMC, "preferred_erase_size" is the high-capacity erase size if a card
specifies one, otherwise it is based on the capacity of the card.
For SD, "preferred_erase_size" is the allocation unit size specified by
the card.
"preferred_erase_size" is in bytes.

There are currently various laptop drivers floating about with no central
place for their documentation, which is currently scattered around the top
level Documentation/ directory.
So, as a first step, lets create a Documentation sub-directory, and update
the relevant index files. The work of then moving the existing laptop
driver related documentation will then be handled later.

People discuss how the namespaces are working/going-to-work together.
Ted Ts'o proposed to create some document that describes what problems user
may have when he/she creates some new namespace, but keeps others shared.
I liked this idea, so here's the initial version of such a document with
the problems I currently have in mind and can describe somewhat audibly -
the "namespaces compatibility list".
The Documentation/namespaces/ directory is about to contain more docs about
the namespaces stuff.
Thanks to Cedirc for notes and spell checks on the doc, to Daniel for
additional info about IPC and User namespaces interaction and to Randy, who
alluded me to using a spell checker before sending the documentation :)
