To clarify that it is a 16-bit checksum, the parts related to the 16-bit
checksum are renamed and change type to u16.
Furthermore, replace checksum calculation in exfat_load_upcase_table()
with exfat_calc_checksum32().

exfat: add boot region verification2020-06-09T07:49:19+00:00Tetsuhiro Kohadakohada.t2@gmail.com2020-05-31T09:30:17+00:00urn:sha1:476189c0ef3b658de3f6b89fd0fdeb6dc451b564
Add Boot-Regions verification specified in exFAT specification.
Note that the checksum type is strongly related to the raw structure,
so the'u32 'type is used to clarify the number of bits.

exfat: replace 'time_ms' with 'time_cs'2020-06-09T07:49:00+00:00Tetsuhiro Kohadakohada.t2@gmail.com2020-04-21T23:30:56+00:00urn:sha1:ed0f84d30ba65f44bed2739572c7ab0fdeed4004
Replace time_ms with time_cs in the file directory entry structure
and related functions.
The unit of create_time_ms/modify_time_ms in File Directory Entry are not
'milli-second', but 'centi-second'.
The exfat specification uses the term '10ms', but instead use 'cs' as in
msdos_fs.h.

Remove the direct use of KERN_<LEVEL> in functions by creating
separate exfat_<level> macros.
Miscellanea:
o Remove several unnecessary terminating newlines in formats
o Realign arguments and fit to 80 columns where appropriate

exfat: truncate atimes to 2s granularity2020-04-22T11:14:06+00:00Eric Sandeensandeen@sandeen.net2020-04-21T02:13:10+00:00urn:sha1:81df1ad40644b706a1cdbd28a1471f9f0c0ea3e8
The timestamp for access_time has double seconds granularity(There is no
10msIncrement field for access_time unlike create/modify_time).
exfat's atimes are restricted to only 2s granularity so after
we set an atime, round it down to the nearest 2s and set the
sub-second component of the timestamp to 0.
