callers of ids__new() function only do NULL checking for the return

Contrary to popular belief, there is no such thing as a default
IPA size on arm64. Anything goes, and implementations are the
usual Wild West.
The selftest infrastructure default to 40bit IPA, which obviously
doesn't work for some systems out there.
Turn VM_MODE_DEFAULT from a constant into a variable, and let
guest_modes_append_default() populate it, depending on what
the HW can do. In order to preserve the current behaviour, we
still pick 40bits IPA as the default if it is available, and
the largest supported IPA space otherwise.

NFT_COUNTER was removed since

LKP/0Day will check if all configs listing under selftests are able to

For the missing configs, it will report something like:
LKP WARN miss config CONFIG_NFT_COUNTER= of net/mptcp/config
- it's not reasonable to keep the deprecated configs.
- configs under kselftests are recommended by corresponding tests.

When BIOS disables turbo, the cpuinfo_max_freq will also be same as the
power up base frequency. When SST-PP causes increase in base frequency
the performance will be still limited to the old base frequency as the
cpuinfo_max_freq will not be updated.
In this case we need to update scaling_max frequency to the new
base_frequency. This will result in setting updated max performance
limit in the Pstate driver. So performance will not be limited to the
old base frequency.

According to ASIC arch, the trap is triggered if overlay packet length is
less than 18B, and the minimum inner packet should include source MAC and
destination MAC.
