tracing: Use strlcpy() instead of strcpy() in __trace_find_cmdline()
Strcpy is inherently not safe, and strlcpy() should be used instead.
__trace_find_cmdline() uses strcpy() because the comms saved must have a
terminating nul character, but it doesn't hurt to add the extra protection
of using strlcpy() instead of strcpy().

acpi: Disable APEI error injection if the kernel is locked down
ACPI provides an error injection mechanism, EINJ, for debugging and testing
the ACPI Platform Error Interface (APEI) and other RAS features. If
supported by the firmware, ACPI specification 5.0 and later provide for a
way to specify a physical memory address to which to inject the error.
Injecting errors through EINJ can produce errors which to the platform are
indistinguishable from real hardware errors. This can have undesirable
side-effects, such as causing the platform to mark hardware as needing
replacement.
While it does not provide a method to load unauthenticated privileged code,

Annotate hardware config module parameters in fs/pstore/
When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image. Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.
To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify. The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.
Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.

Annotate hardware config module parameters in drivers/mmc/host/
When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image. Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.
To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify. The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.
Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.

Annotate module params that specify hardware parameters (eg. ioport)
Provided an annotation for module parameters that specify hardware
parameters (such as io ports, iomem addresses, irqs, dma channels, fixed
dma buffers and other types).
This will enable such parameters to be locked down in the core parameter
parser for secure boot support.
I've also included annotations as to what sort of hardware configuration
each module is dealing with for future use. Some of these are
straightforward (ioport, iomem, irq, dma), but there are also:
(1) drivers that switch the semantics of a parameter between ioport and
iomem depending on a second parameter,
(2) drivers that appear to reserve a CPU memory buffer at a fixed address,
(3) other parameters, such as bus types and irq selection bitmasks.
For the moment, the hardware configuration type isn't actually stored,
though its validity is checked.

Kbuild.include: addtree: Remove quotes before matching path
systemtap currently fails to build modules when the kernel source and
object trees are separate.
systemtap adds something like -I"/usr/share/systemtap/runtime" to
EXTRA_CFLAGS, and addtree should not adjust this as it's specifying an
absolute directory. But since make has no understanding of shell
quoting, it does anyway.
For a long time this didn't matter, because addtree would still emit
the original -I option after the adjusted one. However, commit
db547ef19064 ("Kbuild: don't add obj tree in additional includes")
changed it to remove the original -I option.

x86: Make x32 syscall support conditional on a kernel parameter
Enabling x32 in the standard amd64 kernel would increase its attack
surface while provide no benefit to the vast majority of its users.
No-one seems interested in regularly checking for vulnerabilities
specific to x32 (at least no-one with a white hat).
Still, adding another flavour just to turn on x32 seems wasteful. And
the only differences on syscall entry are two instructions (mask out
the x32 flag and compare the syscall number).
So pad the standard comparison with a nop and add a kernel parameter
"syscall.x32" which controls whether this is replaced with the x32
version at boot time. Add a Kconfig parameter to set the default.

ARM: dts: kirkwood: Fix SATA pinmux-ing for TS419
The old board code for the TS419 assigns MPP pins 15 and 16 as SATA
activity signals (and none as SATA presence signals). Currently the

conflict with the second Ethernet port.

radeon: Firmware is required for DRM and KMS on R600 onward
radeon requires firmware/microcode for the GPU in all chips, but for
newer chips (apparently R600 'Evergreen' onward) it also expects
firmware for the memory controller and other sub-blocks.
radeon attempts to gracefully fall back and disable some features if
the firmware is not available, but becomes unstable - the framebuffer
and/or system memory may be corrupted, or the display may stay black.
