Hi Michael,
Here is the updated version, could you please help to review it again?
As you suggested, this version didn't copy the code, but splitted
the logic into a helper function, so both kernel_map_linear_page() and
__hash_page_huge() can use.
Also patch #1 moves some unnecessary code out of the repeating loop, so the
splitting is easier. Patch #3 removes the HPTE_V_BOLTED flag in
kernel_map_linear_page(), it seems not needed based on my understanding.
Changes are split into smaller ones, so each one did only one thing.
Thanks, Zhong

powerpc: Move the setting of rflags out of loop in __hash_page_huge
powerpc: Split the code trying to insert hpte repeatedly as an helper
function
powerpc: Don't bolt the hpte in kernel_map_linear_page()
powerpc: Try to insert the hptes repeatedly in
kernel_map_linear_page()
