Hi Michael,
Thanks, I will then remove those two specific implementations and we'll
use the generic ones.
I send a v6 asap.
Thanks again,
Alex

Hi Alex,
Sorry missed your previous mail.

Ok, I tried every defconfig available:
- for the nohash/32, I found that I could use mpc885_ads_defconfig and I
activated HUGETLBFS.
I removed the definition of huge_ptep_set_wrprotect from
nohash/32/pgtable.h, add an #error in
include/asm-generic/hugetlb.h right before the generic definition of
huge_ptep_set_wrprotect,
and fell onto it at compile-time:
=> I'm pretty confident then that removing the definition of
huge_ptep_set_wrprotect does not
break anythingin this case.
Thanks, that sounds good.
- regardind book3s/32, I did not find any defconfig with
CONFIG_PPC_BOOK3S_32, CONFIG_PPC32
allowing to enable huge page support (ie CONFIG_SYS_SUPPORTS_HUGETLBFS)
=> Do you have a defconfig that would allow me to try the same as above ?
I think you're right, it's dead code AFAICS.
We have:
config PPC_BOOK3S_64
...
select SYS_SUPPORTS_HUGETLBFS
config PPC_FSL_BOOK3E
...
select SYS_SUPPORTS_HUGETLBFS if PHYS_64BIT || PPC64
config PPC_8xx
...
select SYS_SUPPORTS_HUGETLBFS
So we can't ever enable HUGETLBFS for Book3S 32.
Presumably the code got copied when we split the headers apart.
So I think you can just ignore that one, and we'll delete it.
cheers
