The approach of this patch series seems straightforward, the only nitpick I
have is the fact that two new functions __crst_table_alloc/__page_table_alloc
are introduced. There aren't many call sites for the two original functions,
namely 4 for crst_table_alloc and 3 for page_table_alloc. Why not add the
gfp flag GFP_KERNEL to these call sites? Then the two additional functions
would not be needed.
