The RISC-V ISA only supports flushing the instruction cache for the local

The kernel runs in M-mode without using page tables, and thus can't run

When kallsyms generation happens, temporary vmlinux outputs are linked

Introduce an optional callback in interconnect provider drivers. It can be

The benefit of this for now is that it will significantly simplify the code

Consumers may have use cases with different bandwidth requirements based
on the system or driver state. The consumer driver can append a specific

SoCs that have multiple coexisting CPUs and DSPs, may have shared
interconnect buses between them. In such cases, each CPU/DSP may have
different bandwidth needs, depending on whether it is active or sleeping.
This means that we have to keep different bandwidth configurations for
the CPU (active/sl

This callback allows masters to compute the bus parameters required.
This looks like a partial use of the patch ('soundwire: Add Intel

The last time I used a VT100 was about 30 years ago. I still think
this was one of the most brilliant piece of equ
Bharath,
I do not believe that __get_user_pages_fast will work for the atomic case, as
there is no guarantee that the 'current->mm' will be the correct one for the
process in question, as the process might have moved away from the cpu that is
handling interrupts for it's context.

Remove the default for CONFIG_DRM_MSM and let the user select the driver
manually as one does.
Additionally select QCOM_COMMAND_DB for ARCH_QCOM targets to make sure
it doesn't get missed when we need it for a6xx targets.

Now that CONFIG_DRM_MSM is no longer default 'y' add it as a module to all
ARCH_QCOM enabled defconfigs to restore the previous expected build
