[master/kirkstone,1/5] linux-bb.org: update to 5.10.162 and dedicated branches

From: Denys Dmytriyenko <denys@konsulko.com>

* Update both 32 and 64-bit trees to 5.10.162
* Switch from using a common branch that gets periodically rebased to using
  dedicated per-merge branches
* Patch 32-bit defconfig to use LZMA compression instead of LZO, that is
  being deprecated in OE-Core

Oh! I didn't realize, lzo is in a sorry state.

Our only reason for using lzo over lzma, was purely a boot-up speed
race. (Thinking with the am335x single core at 1Ghz..)

Does OE-Core have proper support for lz4 as a replacement? Or just in
general lzma is the most recommended?

Regards,

Well, lzo is still kind of supported in OE-Core... But since lzop tool has 
been removed (actually, moved to supplemental meta-openembedded layer), you 
can't easily build lzo-compressed kernel w/o extra dependencies.

lzma, lz4, zstd are all supported, with zstd being the hot addition lately. 
Agree, lz4 may be the best choice for low-power devices like am335x...

There is an additional patch in SRC_URI on master.  Does that patch 
remain in the SRC_URI, or should it split out like the armv7a below? 
I'm leaving it in the SRC_URI for my initial testing, I am just looking 
for clarity.

Ah, sorry, missed that extra patch in master to fix perf - yes. that should go 
to the common/generic SRC_URI.
