need to ensure that we pass the warning message the length of the

The Synopsys APB DW UART has a couple of special features that are not
in the System C model. In 3.8, the 8250_dw driver didn't really use these
features, but from 3.9 onwards, the 8250_dw driver has become incompatible
with our model.

Commit 7351d3a5db added an index variable
as part of fixing checkpatch warnings, presumably as a tool to make some
long lines shorter, however it only set that index in the case of there
being no gaps in eccpos for the fragment being read. Which means the
later step of filling ecccode from oob_poi will use the wrong indexing
into eccpos in that case.
This patch restores the behaviour that existed prior to that change.

Sum up sizeof(...) results instead of (incorrectly) hard-coding the
number of bytes, expressed in ints and longs.

Only version 6 of osdmap encoding is supported, anything other than
version 6 results in an error and halts the decoding process. Checking
if version is >= 5 is therefore bogus.

The existing error handling scheme requires resetting err to -EINVAL
prior to calling any ceph_decode_* macro. This is ugly and fragile,
and there already are a few places where we would return 0 on error,
due to a missing reset. Follow osdmap_decode() and fix this by adding
a special e_inval label to be used by all ceph_decode_* macros.

The size of the memory area feeded to crush_decode() should be limited
not only by osdmap end, but also by the crush map length. Also, drop
unnecessary dout() (dout() in crush_decode() conveys the same info) and
step past crush map only if it is decoded successfully.

Check length of osd_state, osd_weight and osd_addr arrays. They
should all have exactly max_osd elements after the call to
osdmap_set_max_osd().

max_osd value is not covered by any ceph_decode_need(). Use a safe
version of ceph_decode_* macro to decode it.
