Running 32-bit binaries is quite seriously broken until this is fixed. I presume this currently isn't on anyone's list to fix? I'm not sure who's list it should go on.

Are you running with 4KB or 64KB page size in the kernel? IIRC you cannot really run 32-bit binaries with 64KB page size because of related issues.

I'm not sure. The kernel config has: CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y # CONFIG_ARM64_64K_PAGES is not set CONFIG_PAGEFLAGS_EXTENDED=y # CONFIG_TRANSPARENT_HUGEPAGE is not set

Is that using 64K pages or not?

Is there a dynamic switch I can twiddle or does it need a kernel rebuild?
