Subject: [PATCH v6 00/11] hugetlb: Factorize hugetlb architecture primitives 
Date:   Mon,  6 Aug 2018 17:57:00 +0000

[CC linux-mm for inclusion in -mm tree]                                          
                                                                                 
In order to reduce copy/paste of functions across architectures and then         
make riscv hugetlb port (and future ports) simpler and smaller, this             
patchset intends to factorize the numerous hugetlb primitives that are           
defined across all the architectures.                                            
                                                                                 
Except for prepare_hugepage_range, this patchset moves the versions that         
are just pass-through to standard pte primitives into                            
asm-generic/hugetlb.h by using the same #ifdef semantic that can be              
found in asm-generic/pgtable.h, i.e. __HAVE_ARCH_***.                            
                                                                                 
s390 architecture has not been tackled in this serie since it does not           
use asm-generic/hugetlb.h at all.                                                
                                                                                 
This patchset has been compiled on all addressed architectures with              
success (except for parisc, but the problem does not come from this              
series).                                                                         
                                                                                 
v6:                                                                              
  - Remove nohash/32 and book3s/32 powerpc specific implementations in
    order to use the generic ones.                                                        
  - Add all the Reviewed-by, Acked-by and Tested-by in the commits,              
    thanks to everyone.                                                          
                                                                                 
v5:                                                                              
  As suggested by Mike Kravetz, no need to move the #include                     
  <asm-generic/hugetlb.h> for arm and x86 architectures, let it live at          
  the top of the file.                                                           
                                                                                 
v4:                                                                              
  Fix powerpc build error due to misplacing of #include                          
  <asm-generic/hugetlb.h> outside of #ifdef CONFIG_HUGETLB_PAGE, as              
  pointed by Christophe Leroy.                                                   
                                                                                 
v1, v2, v3:                                                                      
  Same version, just problems with email provider and misuse of                  
  --batch-size option of git send-email
