Subject: [PATCH 0/2] Request to test fix for "x86/Kconfig: select HAVE_ARCH_HUGE_VMALLOC with HAVE_ARCH_HUGE_VMAP)"

Hi Paul,

If it's not too much trouble would you be able to run your test case
https://lore.kernel.org/all/14444103-d51b-0fb3-ee63-c3f182f0b546@molgen.mpg.de/
on upstream tree plus these two patches to see if any errors persist?

To be clear, you shouldn't see such issues with upstream now, but I
would like to see if they are solved with this fix when we re-enable
huge vmalloc for drivers.

Thanks,
Nick
