No functional change in this patch. arch_debugfs_dir is the generic kernel
name declared in linux/debugfs.h for arch-specific debugfs directory.
Architectures like x86/s390 already use the name. Rename powerpc
specific powerpc_debugfs_root to arch_debugfs_dir.

Not sure how TDX will handle AP booting, are you sure it needs this
special setup as well? Otherwise a check for SEV-ES would be better
instead of the generic PATTR_GUEST_PROT_STATE.
Yes, I'm not sure either. I figure that change can be made, if needed,

The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_irq() (which takes
*unsigned* IRQ #), causing it to fail with -EINVAL, overriding an original
error code. Stop calling request_irq() with the invalid IRQ #s.

Thanks,
I've applied this to the dma-mapping tree with a few minor cosmetic
tweaks.
