Same story as with olympic - htons(readw()) when swab16(readw()) is needed,
missing conversions to le32 when dealing with shared descriptors, etc.

Both store MAC address in CIS; there's no decoder for that
type (0x88) so the drivers work with raw data. It is
byteswapped, so ntohs() works for little-endian, but for
big-endian it's wrong. ntohs(le16_to_cpu()) does the
right thing on both (and always expands to swab16()).

Fix possible max_phys_segments violation in cloned dm-crypt bio.
In write operation dm-crypt needs to allocate new bio request
and run crypto operation on this clone. Cloned request has always
the same size, but number of physical segments can be increased
and violate max_phys_segments restriction.
This can lead to data corruption and serious hardware malfunction.
This was observed when using XFS over dm-crypt and at least
two HBA controller drivers (arcmsr, cciss) recently.
Fix it by using bio_add_page() call (which tests for other
restrictions too) instead of constructing own biovec.
All versions of dm-crypt are affected by this bug.

This patch fixes a panic on shrinking a DM device if there is
outstanding I/O to the part of the device that is being removed.
(Normally this doesn't happen - a filesystem would be resized first,
for example.)
The bug is that __clone_and_map() assumes dm_table_find_target()
always returns a valid pointer. It may fail if a bio arrives from the
block layer but its target sector is no longer included in the DM
btree.
This patch appends an empty entry to table->targets[] which will
be returned by a lookup beyond the end of the device.
After calling dm_table_find_target(), __clone_and_map() and target_message()
check for this condition using
dm_target_is_valid().

if log_len is larger than 4K then we are killing the stack.

tg3_nvram_write_block_unbuffered() is reading data from nvram into
allocated buffer before overwriting a part of it with user-supplied
data. Then it feeds the entire page back to nvram. It should be
storing the words it had read as little-endian, not as host-endian.
Note that tg3_set_eeprom() does exactly that for padding the same
data to full words before it gets passed down to tg3_nvram_write_block()
and then to tg3_nvram_write_block_unbuffered().
Moreover, when we get to sending the entire thing back to nvram, we
go through it word-by-word, doing essentially
writel(swab32(le32_to_cpu(word)), ...)
so if we want them to reach the card in host-independent endianness,
we'd better really have all that buffer filled with fixed-endian.
For user-supplied part we obviously do have that (it's an array of
octets memcpy'd in), ditto for padding of user-supplied part to word
boundaries (taken care of in tg3_set_eeprom()). The rest of the
buffer gets filled by tg3_nvram_write_block_unbuffered() and it would
damn better be consistent with that (and with tg3_get_eeprom(), while
we are at it - there we also convert the words read from nvram to
little-endian before returning the buffer to user).
The bug should get triggered on big-endian boxen when set_eeprom is done
for less than entire page. Then the words that should've been unaffected
at all will actually get byteswapped in place in nvram.

Fixed misannotations, introduced a new helper - tg3_nvram_read_le().
It gets __le32 * instead of u32 * and puts there the value converted
to little-endian. A lot of callers of tg3_nvram_read() were doing
that; converted them to tg3_nvram_read_le().
At that point the driver is practically endian-clean; the only remaining
place is an actual bug, AFAICS; will be dealt with in the next patch.
