Some StrongARM processors don't support suspend, which leads
to a build failure with the tegra cpuidle driver:
WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND

Arnd, thank you for the patch!
Apparently ARM_QCOM_SPM_CPUIDLE doesn't have that problem visible
because it selects QCOM_SPM, which depends on ARCH_QCOM, and thus
ARCH_QCOM should be auto-selected(?). I'm curious whether this needs to
be corrected, otherwise (ARCH_QCOM || COMPILE_TEST) doesn't make much
sense for that driver. And then it will need the same Kconfig fix as well.
I assume this problem wasn't caught by regular kernel build bots because
they don't test randconfig, don't they?

No, that's not how it works. In fact ARM_QCOM_SPM_CPUIDLE has the
exact same problem. I tried to check if there are other drivers affected
by this problem before I sent my patch, but I did something wrong and
missed this one.

They do test randconfig builds, but only a few of them. This one is
rather hard to hit, it probably took me 100 builds before I hit the first
one and I haven't run into the QCOM one yet, though I did see a
different issue for ARM_QCOM_SPM_CPUIDLE:
WARNING: unmet direct dependencies detected for QCOM_SPM
Depends on [n]: ARCH_QCOM [=n]
Selected by [y]:
- ARM_QCOM_SPM_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64)

Thanks!
I realized now that we should drop the '&& MMU' after my fix, for both
the tegra and qualcomm drivers, reverting the change from 498ba2a8a275
("cpuidle: Fix ARM_QCOM_SPM_CPUIDLE configuration") that got failed
to fix this problem. I'll resend it as a series of three patches with your R-b
on this patch.
On a related note, I now see that the "||COMPILE_TEST" bit for the
arm-specific cpuidle drivers is not all that useful because we can curently
not hit that on non-ARM machines at all. I'll try changing that as well, but
this is probably nontrivial.

What is the status of this patch, please?
kernel test robot is still reporting this build error, so I just
created the same patch...
thanks.
