Please avoid the completely unreadably long line. i.e.
int isolate_single_pageblock(unsigned long boundary_pfn, gfp_t gfp_flags,
int isolate_before_boundary);

Dear PPC folks,
On the POWER8 server IBM S822LC running `ppc64_cpu --smt=off` or
`ppc64_cpu --smt=8`, Linux 5.17-rc4 does not log anything. I would have
expected a message about the change in number of processing units.
Kind regards,
Paul

This defines and exports a platform specific custom vm_get_page_prot() via
subscribing ARCH_HAS_VM_GET_PAGE_PROT. Subsequently all __SXXX and __PXXX
macros can be dropped which are no longer needed. While here, this also
localizes arch_vm_get_page_prot() as powerpc_vm_get_page_prot() and moves
it

Hi Ahmad-san,
Thanks for your confirmations. Sorry for late to reply.
Could you please try the patch attached to disable the chip_good()
change as before?
I think this should work for S29GL964N since the chip_ready() is used
and works as mentioned.

Warnings in assembly must use EMIT_WARN_ENTRY in order to generate
the necessary entry in exception table.
Check in EMIT_BUG_ENTRY that flags don't include BUGFLAG_WARNING.
This change avoids problems like the one fixed by
