evm: add Kconfig TCG_TPM dependency
Although the EVM encrypted-key should be encrypted/decrypted using a
trusted-key, a user-defined key could be used instead. When using a user-
defined key, a TCG_TPM dependency should not be required. Unfortunately,
the encrypted-key code needs to be refactored a bit in order to remove
this dependency.
This patch adds the TCG_TPM dependency.

Initial EXPERIMENTAL implementation of device-mapper thin provisioning
with snapshot support. The 'thin' target is used to create instances of
the virtual devices that are hosted in the 'thin-pool' target. The
thin-pool target provides data sharing among devices. This sharing is
made possible using the persistent-data library in the previous patch.
The main highlight of this implementation, compared to the previous
implementation of snapshots, is that it allows many virtual devices to
be stored on the same data volume, simplifying administration and
allowing sharing of data between volumes (thus reducing disk usage).
Another big feature is support for arbitrary depth of recursive
snapshots (snapshots of snapshots of snapshots ...). The previous
implementation of snapshots did this by chaining together lookup tables,
and so performance was O(depth). This new implementation uses a single
data structure so we don't get this degradation with depth.
For further information and examples of how to use this, please read
Documentation/device-mapper/thin-provisioning.txt

This patch introduces dm_kcopyd_zero() to make it easy to use
kcopyd to write zeros into the requested areas instead
instead of copying. It is implemented by passing a NULL
copying source to dm_kcopyd_copy().
The forthcoming thin provisioning target uses this.

The code that prepares the SG associated with SCSI command for FMR was
buggy for systems with DMA addresses that don't fit in unsigned long,
e.g under the 32-bit based XenServer dom0 sizeof(dma_addr_t) is 8.
Fix that by casting to unsigned long long a masking constant used by
the code. This resolves a crash in iser_sg_to_page_vec on this system.

fat: fat16 support maximum 4GB file/vol size as WinXP or 7.
FAT16 support maximum 4GB vol/file size with 64KB cluster size.
Win NT/XP/7 increased the maximum cluster size to 64KB, and file/vol
size increased 4GB also. Although increasing, the file size of linux
FAT is still limited at 2GB.
I found that it is limited by sb->maxbytes(0x7fffffff) when partition
is formatted by FAT16. sb->s_maxbytes in fill_super should be set to
0xffffffff like fat32.
