Since syzbot is confused by concurrent printk() messages [1],
this patch changes show_opcodes() to use %ph format string.
When we start adding prefix to each line of printk() output,
we will be able to handle concurrent printk() messages.

Since syzbot is hitting crashes too frequently to capture vmcore for later
analysis, currently we need to rely on printk()-based analysis. And I'm
planning to add a kernel config option for additional printk() etc. for
testing under syzbot environment.
One of missing printk() is in khungtaskd.

Currently if a timeout on rdma happens we just go ahead and reset the
underlying transport.
Instead try to abort the timeout out command and if this fails as well
continue the error path escalation and tear down the transport.

Embedded memory controller has a corresponding clock, document the clock

Kernel should never gate the EMC clock as it causes immediate lockup, so
removing clk-gate functionality doesn't affect anything. Turning EMC clk
gate into divider allows to implement glitch-less EMC scaling, avoiding
reparenting to a backup clock.

Ensure that direct PLLM sourcing is turned off for EMC as we don't support
that configuration in the clk driver.

Hello,
Couple years ago the Tegra20 EMC driver was removed from the kernel
due to incompatible changes in the Tegra's clock driver. This patchset
introduces a modernized EMC driver. Currently the sole purpose of the
driver is to initialize DRAM frequency to maximum rate during of the
kernels

Introduce driver for the External Memory Controller (EMC) found on Tegra20
chips, which controls the external DRAM on the board. The purpose of this
driver is to program memory timing for external memory on the EMC clock
rate change.

EMC has a dedicated interrupt that is used to notify about completion of
HW operations. Document the interrupt property.
