Meelis, this patch should fix both issues.
Can you test?
At least one of the warnings is still there - but I am on a 64-bit
kernel on RP3440, RP3410 and A500 where I saw this.
Details?
The ones you sent were 32bit issues (with 1024 bytes frame-size-warning):
fs/select.c:991:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
arch/parisc/kernel/inventory.c:359:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=]

[PATCH] parisc: Fix too large frame size warnings
The parisc architecture requires larger stack frames than most other
architectures on 32-bit kernels.
Increase the default to 1280 bytes for parisc to avoid warnings in
do_sys_poll() and pat_memconfig() functions.

Tell gcc to warn at build time for stack frames larger than this.
