The optional type 15 entry of the DMI table describes a non-volatile
storage-backed system event log.

In preparation for the next commit which exposes the raw bits of the
event log to userland, create a new sub-directory within the dmi entry
called "system_event_log" and expose attribute files that describe the
event log itself.

Currently, only a single child object is permitted within a
dmi_sysfs_entry.  We simply point at this child from the dmi_sysfs_entry
if it exists.

Introduce a new module "dmi-sysfs" that exports the broken out entries
of the DMI table through sysfs.

Entries are enumerated via dmi_walk() on module load, and are populated
as kobjects rooted at /sys/firmware/dmi/entries.

Entries are named "<type>-<instance>", where:
   <type>	: is the type of the entry, and
   <instance>	: is the ordinal count within the DMI table of that
		  entry type.  This instance is used in lieu the DMI
		  entry's handle as no assurances are made by the kernel
		  that handles are unique.

All entries export the following attributes:
   length	: The length of the formatted portion of the entry
   handle	: The handle given to this entry by the firmware
   raw		: The raw bytes of the entire entry, including the
		  formatted portion, the unformatted (strings) portion,
		  and the two terminating nul characters.
   type		: The DMI entry type
   instance	: The ordinal instance of this entry given its type.
   position	: The position ordinal of the entry within the table in
		  its entirety.

Entries in dmi-sysfs are kobject backed members called "struct
dmi_sysfs_entry" and belong to dmi_kset.  They are threaded through
entry_list (protected by entry_list_lock) so that we can find them at
cleanup time.

Where file-transfer stops/pauses in between, is
result of a HCI-LL anamoly in ST LL driver.
ST LL did not copy the contents of WaitQ into the TxQ, when a WAKEUP_IND
collision happened.
Make also sure, that the copying mechanism is safe, by wrapping it around
spin locks inside st_int_recv().
This was easily reproduced when the sleep timeout was reduced to 100ms

To fasten the process of firmware download, the chip allows
disabling of the command complete event generation from host.
In these cases, only few very essential commands would have
the command complete events and hence the wait associated with
them.

So now the driver would wait for a command complete event, only
when it comes across a wait event during firmware parsing.
This would also mean we need to skip not just the change baud
rate command but also the wait for it.

The communication between ST KIM and UIM was interfaced
over the /dev/rfkill device node.
Move the interface to a simpler less abusive sysfs entry
mechanism and document it in Documentation/ABI/testing/
under sysfs-platform-kim.

Shared transport driver would now read the UART details
originally received by bootloader or firmware as platform
data.
The data read will be shared over sysfs entries for the user-space
UIM or other n/w manager/plugins to be read, and assist the driver
by opening up the UART, setting the baud-rate and installing the
line discipline.

The architecture of shared transport had begun with individual
protocols like bluetooth, fm and gps telling the shared transport
what sort of protocol they are and then expecting the ST driver
to parse the incoming data from chip and forward data only
relevant to the protocol drivers.

This change would mean each protocol drivers would also send
information to ST driver as to how to intrepret their protocol
data coming out of the chip.

As a follow-on to the recent patches I submitted that allowed for a sysfs
memory block to span multiple memory sections, we should also update the
probe routine to online all of the memory sections in a memory block.  Without
this patch the current code will only add a single memory section.  I think
the probe routine should add all of the memory sections in the specified memory
block so that its behavior is in line with memory hotplug actions through
the sysfs interfaces.

This patch applies on top of the previous sysfs memory updates to allow
a sysfs directory o span multiple memory sections.

Update the 'phys_index' property of a the memory_block struct to be
called start_section_nr, and add a end_section_nr property.  The
data tracked here is the same but the updated naming is more in line
with what is stored here, namely the first and last section number
that the memory block spans.

The names presented to userspace remain the same, phys_index for
start_section_nr and end_phys_index for end_section_nr, to avoid breaking
anything in userspace.

This also updates the node sysfs code to be aware of the new capability for
a memory block to contain multiple memory sections and be aware of the memory
block structure name changes (start_section_nr).  This requires an additional
parameter to unregister_mem_sect_under_nodes so that we know which memory
section of the memory block to unregister.

Update the memory sysfs code such that each sysfs memory directory is now
considered a memory block that can span multiple memory sections per
memory block.  The default size of each memory block is SECTION_SIZE_BITS
to maintain the current behavior of having a single memory section per
memory block (i.e. one sysfs directory per memory section).

For architectures that want to have memory blocks span multiple
memory sections they need only define their own memory_block_size_bytes()
routine.

Update the memory hotplug documentation to reflect the new behaviors of
memory blocks reflected in sysfs.
