Hey.
Perhaps someone can help me with this.
I got a brand new notebook from the university, a Fujitsu U757[0][1],

In variable timer reading loops, pick up just the values until all
are synchronized, then outside of loop pick up cntvct and perform
calculations to determine final offset, shifted and multiplied
output value.
This replaces get_ns with get_clock_shifted_nsec as cntvct reader.

Rename seq_count to tb_seq_count. Rename tk_is_cntvct to use_syscall.
Rename cs_mult to cs_mono_mult. All to align with the variables in the

Define the prototype for __get_datapage() in local datapage.h header.
Rename all vdata variable that point to the datapage shortened to vd

Help identify to the user the event with the unsupported sampling
error. Also provide an alternative action.

$ sudo ./oldperf record -e

Error:
PMU Hardware doesn't support sampling/overflow-interrupts.

There is a misprint in error handling of pinctrl_lookup_state(),
where qcom_usb_hsic_phy_power_on() does return instead of goto err_ulpi.
Found by Linux Driver Verification project (linuxtesting.org).

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
Notice that in this particular case I replaced "...drop on through"
comments with a proper "fall through" comment on its own line, which
is what GCC is expecting to find.

Huh, FW is in INIT state and PEK_GEN wants it to be in INIT state. Typo?
