Found in B-5.0-oracle as well.

[Po-Hsu Lin (cypressyew)]

For B-5.0-oracle, this issue can be reproduced on VM.Standard1.4

but not VM.DenseIO1.8 (test shows umip_basic_test.c:151: CONF: cpuinfo show: cpu does not support umip)

[Po-Hsu Lin (cypressyew)]

Found on B-4.15 Oracle 4.15.0-1039.43-oracle
VM.Standard2.1
VM.Standard2.16

[Po-Hsu Lin (cypressyew)]

In this test it says:
 * Intel CPU of ICE lake or newer is required for the test
 * kconfig requirement:CONFIG_X86_INTEL_UMIP=y

Need to check what we have here for Oracle clouds.

[Po-Hsu Lin (cypressyew)]

Failed on Eoan Oracle 5.3.0-1030.32 with instance VM.Standard2.1

But passed with VM.Standard2.16

[Po-Hsu Lin (cypressyew)]

on VM.Standard2.16, the test will be skipped with:
umip_basic_test.c:151: CONF: cpuinfo show: cpu does not support umip
