The binder_buffer allocator currently only allocates
space for the data and offsets buffers of a Parcel.
This change allows for requesting an additional chunk
of data in the buffer, which can for example be used
to hold additional meta-data about the transaction
(eg a security context).

Add a new module parameter 'devices', that can be
used to specify the names of the binder device
nodes we want to populate in /dev.
Each device node has its own context manager, and
is therefore logically separated from all the other
device nodes.
The config option CONFIG_ANDROID_BINDER_DEVICES can
be used to set the default value of the parameter.
This approach was favored over using IPC namespaces,
mostly because we require a single process to be a
part of multiple binder contexts, which seemed harder
to achieve with namespaces.

flat_binder_object is used for both handling
binder objects and file descriptors, even though
the two are mostly independent. Since we'll
have more fixup objects in binder in the future,
instead of extending flat_binder_object again,
split out file descriptors to their own object
while retaining backwards compatibility to
existing user-space clients. All binder objects
just share a header.

[neeraju@codeaurora.org: resolve trivial merge conflicts]

The frequency requested by LMH DCVSh hardware may not match an actual
frequency in the CPU clock plan. LMH DCVSh driver uses OPP framework to
match the hardware frequency request to a nearest valid CPU frequency. OPP
interface expects the frequency input in Hz and DCVSh driver is passing the
frequency value in kHz, which will result in error. So the hardware
mitigation frequency reported by the driver may not reflect the actual
frequency that the CPU is mitigated to.
Provide the hardware frequency input in Hz for OPP interface in LMH DCVSh
driver. Hardware mitigation frequency can be lower than the lowest
possible CPU frequency. In that case freq floor call will fail. So call
dev_pm_opp_find_freq_ceil to match to the lowest CPU frequency.

rmnet_data netlink handler currently does not check for the
incoming process pid and instead just loops back the pid.
A malicious root user could potentially send a message with
source pid 0 and this could cause rmnet_data to loop the message
back till an out of memory situation occurs.
rmnet_data also does not check for the message length of the
incoming netlink messages and instead casts the netlink message
without checking for the boundary.
Fix these two scenarios by adding the pid and message length checks
respectively.
