Use div_s64 so that the neg_adj is not needed.

Add idt82p33_adjphase() to support PHC write phase mode.
Changes since v1:
-Fix broken build

Refactor idt82p33_xfer and use i2c_master_send for write operation.
Because some I2C controllers are only working with single-burst write
transaction.

Replace the (secctx,seclen) pointer pair with a single
lsmcontext pointer to allow return of the LSM identifier
along with the context and context length. This allows
security_release_secctx() to know how to release the
context. Callers have been modified to use or save the
returned data from the n
Add a new lsmcontext data structure to hold all the information
about a "security context", including the string, its size and
which LSM allocated the string. The allocation information is
necessary because LSMs have different policies regarding the
lifecycle of these strings. SELinux allocates and
Change the security_task_getsecid() interface to fill in
a lsmblob structure instead of a u32 secid in support of
LSM stacking. Audit interfaces will need to collect all
possible secids for possible reporting.

One more trivial thing detected by checkpatch:
ERROR: trailing whitespace
#41: FILE: drivers/ptp/ptp_idt82p33.c:1
Change security_secid_to_secctx() to take a lsmblob as input
instead of a u32 secid. It will then call the LSM hooks
using the lsmblob element allocated for that module. The
callers have been updated as well. This allows for the
possibility that more than one module may be called upon
to translate
Change the security_secctx_to_secid interface to use a lsmblob
structure in place of the single u32 secid in support of
module stacking. Change its callers to do the same.
The security module hook is unchanged, still passing back a secid.
The infrastructure passes the correct entry from the lsmblo
