gpio: Allow per-parent interrupt data
The core gpiolib code is able to deal with multiple interrupt parents
for a single gpio irqchip. It however only allows a single piece
of data to be conveyed to all flow handlers (either the gpio_chip
or some other, driver-specific data).
This means that drivers have to go through some interesting dance
to find the correct context, something that isn't great in interrupt
context (see
aebdc8abc9db86e2bd33070fc2f961012fff74b4 for a prime
example).
Instead, offer an optional way for a pinctrl/gpio driver to provide
an array of pointers which gets used to provide the correct context
to the flow handler.

perf tools: Allow build-id with trailing zeros
Currently perf saves a build-id with size but old versions assumes the
size of 20. In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.
I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data. The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

different size (16) when it reads the build-id of the elf file in the
build-id cache.
