Currently we are leaking addresses from the kernel to user space. This
script is an attempt to find some of those leakages. Script parses
`dmesg` output and /proc and /sys files for hex strings that look like
kernel addresses.
Only works for 64 bit kernels, the reason being that kernel addresses on
64 bit kernels have 'ffff' as the leading bit pattern making greping
possible. On 32 kernels we don't have this luxury.
Scripts is _slightly_ smarter than a straight grep, we check for false
positives (all 0's or all 1's, and vsyscall start/finish addresses).
[ I think there is a lot of room for improvement here, but it's already
useful, so I'm merging it as-is. The whole "hash %p format" series is
expected to go into 4.15, but will not fix %x users, and will not
incentivize people to look at what they are leaking. - Linus ]

This application uses the character device /dev/wmi/dell-smbios
to perform SMBIOS communications from userspace.
It offers demonstrations of a few simple tasks:
- Running a class/select command
- Querying a token value
- Activating a token

For WMI operations that are only Set or Query readable and writable sysfs
attributes created by WMI vendor drivers or the bus driver makes sense.
For other WMI operations that are run on Method, there needs to be a
way to guarantee to userspace that the results from the method call
belong to the data request to the method call. Sysfs attributes don't
work well in this scenario because two userspace processes may be
competing at reading/writing an attribute and step on each other's
data.
When a WMI vendor driver declares a callback method in the wmi_driver
the WMI bus driver will create a character device that maps to that
function. This callback method will be responsible for filtering
invalid requests and performing the actual call.
That character device will correspond to this path:
/dev/wmi/$driver
Performing read() on this character device will provide the size
of the buffer that the character device needs to perform calls.
This buffer size can be set by vendor drivers through a new symbol
or when MOF parsing is available by the MOF.
Performing ioctl() on this character device will be interpretd
by the WMI bus driver. It will perform sanity tests for size of
data, test them for a valid instance, copy the data from userspace
and pass iton to the vendor driver to further process and run.
This creates an implicit policy that each driver will only be allowed
a single character device. If a module matches multiple GUID's,
the wmi_devices will need to be all handled by the same wmi_driver.
The WMI vendor drivers will be responsible for managing inappropriate
access to this character device and proper locking on data used by
it.
When a WMI vendor driver is unloaded the WMI bus driver will clean
up the character device and any memory allocated for the call.

The dell-smbios stack only currently uses an SMI interface which grants
direct access to physical memory to the firmware SMM methods via a pointer.
This dispatcher driver adds a WMI-ACPI interface that is detected by WMI
probe and preferred over the SMI interface in dell-smbios.
Changing this to operate over WMI-ACPI will use an ACPI OperationRegion
for a buffer of data storage when SMM calls are performed.
This is a safer approach to use in kernel drivers as the SMM will
only have access to that OperationRegion.

This splits up the dell-smbios driver into two drivers:
* dell-smbios
* dell-smbios-smm
dell-smbios can operate with multiple different dispatcher drivers to
perform SMBIOS operations.
Also modify the interface that dell-laptop and dell-wmi use align to this
model more closely. Rather than a single global buffer being allocated
for all drivers, each driver will allocate and be responsible for it's own
buffer. The pointer will be passed to the calling function and each
dispatcher driver will then internally copy it to the proper location to
perform it's call.
Add defines for calls used by these methods in the dell-smbios.h header
for tracking purposes.

Currently userspace tools can access system tokens via the dcdbas
kernel module and a SMI call that will cause the platform to execute
SMM code.
With a goal in mind of deprecating the dcdbas kernel module a different
method for accessing these tokens from userspace needs to be created.
This is intentionally marked to only be readable as a process with
CAP_SYS_ADMIN as it can contain sensitive information about the
platform's configuration.
While adding this interface I found that some tokens are duplicated.
These need to be ignored from sysfs to avoid duplicate files.
MAINTAINERS was missing for this driver. Add myself and Pali to
maintainers list for it.

All communication on individual GUIDs should occur in separate drivers.
Allowing a driver to communicate with the bus to another GUID is just
a hack that discourages drivers to adopt the bus model.
The information found from the WMI descriptor driver is now exported
for use by other drivers.

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.
