Encrypted keys are encrypted/decrypted using either a trusted or
user-defined key type, which is referred to as the 'master' key.
The master key may be of type trusted iff the trusted key is
builtin or both the trusted key and encrypted keys are built as
modules. This patch resolves the build dependency problem.
- Use "masterkey-$(CONFIG_TRUSTED_KEYS)-$(CONFIG_ENCRYPTED_KEYS)" construct
to encapsulate the above logic. (Suggested by Dimtry Kasatkin.)
- Fixing the encrypted-keys Makefile, results in a module name change
from encrypted.ko to encrypted-keys.ko.
- Add module dependency for request_trusted_key() definition

In hundreds of days, the __cycles_2_ns calculation in sched_clock
has an overflow. cyc * per_cpu(cyc2ns, cpu) exceeds 64 bits, causing
the final value to become zero. We can solve this without losing
any precision.
We can decompose TSC into quotient and remainder of division by the
scale factor, and then use this to convert TSC into nanoseconds.

The management protocol uses a single byte for error codes (aka command

other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.
To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

The kernel needs to know whether it should connect to a device over

The reg_defaults field usually points to a static per driver array, which should
not be modified. Make requirement this explicit by making reg_defaults const.
To allow this the regcache_init code needs some minor changes. Previoulsy the

to pass the default register set to regcache_init. Now that the reg_config is

HID 1.11 specification, section 5.10 tells us:
HID class devices support the ability to ignore selected fields in a
report at run- time. This is accomplished by declaring bit field in a
report that is capable of containing a range of values larger than
those actually generated by the control. If the host or the device
receives an out-of-range value then the current value for the
respective control will not be modified.
So we shouldn't be restricted to EV_ABS only.
