Avoid returning a truncated table or status string instead of setting
the DM_BUFFER_FULL_FLAG when the last target of a table fills the
buffer.
When processing a table or status request, the function retrieve_status
calls ti->type->status. If ti->type->status returns non-zero,
retrieve_status assumes that the buffer overflowed and sets
DM_BUFFER_FULL_FLAG.
However, targets don't return non-zero values from their status method
on overflow. Most targets returns always zero.
If a buffer overflow happens in a target that is not the last in the
table, it gets noticed during the next iteration of the loop in
retrieve_status; but if a buffer overflow happens in the last target, it
goes unnoticed and erroneously truncated data is returned.
In the current code, the targets behave in the following way:
* dm-crypt returns -ENOMEM if there is not enough space to store the
key, but it returns 0 on all other overflows.
* dm-thin returns errors from the status method if a disk error happened.
This is incorrect because retrieve_status doesn't check the error
code, it assumes that all non-zero values mean buffer overflow.
* all the other targets always return 0.
This patch changes the ti->type->status function to return void (because
most targets don't use the return code). Overflow is detected in
retrieve_status: if the status method fills up the remaining space
completely, it is assumed that buffer overflow happened.

The regression was introduced by the change
c0820cf5 "dm: introduce per_bio_data", where dm started to replace
bioset during table replacement.
For bio-based dm, it is good because clone bios do not exist during the
table replacement.
For request-based dm, however, (not-yet-mapped) clone bios may stay in
request queue and survive during the table replacement.
So freeing the old bioset could cause the oops in bio_put().
Since the size of front_pad may change only with bio-based dm,
it is not necessary to replace bioset for request-based dm.

Commit 0cc41e4a21 (arch: remove direct definitions of KERN_<LEVEL>

.asciz "string"
to
.asciz "string1" "string2"
The problem is that each string gets _separately_ NUL terminated, so
the result is a string containing:
"string1\0string2\0"
rather than:
"string1string2\0"
With our new printk levels, this ends up as - eg, KERN_DEBUG "string":
0x01 0x00 0x07 0x00 "string" 0x00
which produces lots of \x01 in the kernel log.

Apparently when we do inline extents we allow the data to overlap the last chunk
of the btrfs_file_extent_item, which means that we can possibly have a
btrfs_file_extent_item that isn't actually as large as a btrfs_file_extent_item.
This messes with us when we try to overwrite the extent when logging new extents
since we expect for it to be the right size. To fix this just delete the item
and try to do the insert again which will give us the proper sized
btrfs_file_extent_item. This fixes a panic where map_private_extent_buffer
would blow up because we're trying to write past the end of the leaf. Thanks,

we would call the PHYSDEVOP_map_pirq 'nvec' times with the same

reused the hopefully(!) already remapped RTC registers). Also, this
driver is mach independent, while the old one depends on a mach replaced
