These patches addgeneric versions of these functions in and enableuse of the generic functions where appropriate.In addition, functions declared and defined in headers areused mostly by core mm and early mm initialization in arch and there is noactual reason to have the included all over the place.The first patch in this series removes unneeded includes ofIn the end it didn't work out as neatly as I hoped and movingpXd_alloc_track() definitions to would requireunnecessary changes to arches that have custom page table allocations, soI've decided to move lib/ioremap.c to mm/ and make pgalloc-track.h localto mm/.This patch (of 8):In most cases header is required only for allocations ofpage table memory. Most of the .c files that include that header do notuse symbols declared in and do not require that header.As for the other header files that used to include , it ispossible to move that include into the .c file that actually uses symbolsfrom and drop the include from the header file.The process was somewhat automated using sed -i -E '/[<"]asm\/pgalloc\.h/d' \ $(grep -L -w -f /tmp/xx \ $(git grep -E -l '[<"]asm/pgalloc\.h'))where /tmp/xx contains all the symbols defined inarch/*/include/asm/pgalloc.h.[rppt@linux.ibm.com: fix powerpc warning]Signed-off-by: Mike Rapoport Signed-off-by: Andrew Morton Reviewed-by: Pekka Enberg Acked-by: Geert Uytterhoeven [m68k]Cc: Abdul Haleem Cc: Andy Lutomirski Cc: Arnd Bergmann Cc: Christophe Leroy Cc: Joerg Roedel Cc: Max Filippov Cc: Peter Zijlstra Cc: Satheesh Rajendran Cc: Stafford Horne Cc: Stephen Rothwell Cc: Steven Rostedt Cc: Joerg Roedel Cc: Matthew Wilcox Link: http://lkml.kernel.org/r/20200627143453.31835-1-rppt@kernel.orgLink: http://lkml.kernel.org/r/20200627143453.31835-2-rppt@kernel.orgSigned-off-by: Linus Torvalds List of files: /linux-6.15/arch/x86/kernel/mpparse.c
