      "message": "[PATCH] Four level pagetables for ppc64\n\nImplement 4-level pagetables for ppc64\n\nThis patch implements full four-level page tables for ppc64, thereby\nextending the usable user address range to 44 bits (16T).\n\nThe patch uses a full page for the tables at the bottom and top level,\nand a quarter page for the intermediate levels.  It uses full 64-bit\npointers at every level, thus also increasing the addressable range of\nphysical memory.  This patch also tweaks the VSID allocation to allow\nmatching range for user addresses (this halves the number of available\ncontexts) and adds some #if and BUILD_BUG sanity checks.\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"

      "message": "[PATCH] ppc64: Abolish ioremap_mm\n\nCurrently ppc64 has two mm_structs for the kernel, init_mm and also\nioremap_mm.  The latter really isn\u0027t necessary: this patch abolishes it,\ninstead restricting vmallocs to the lower 1TB of the init_mm\u0027s range and\nplacing io mappings in the upper 1TB.  This simplifies the code in a number\nof places and eliminates an unecessary set of pagetables.  It also tweaks\nthe unmap/free path a little, allowing us to remove the unmap_im_area() set\nof page table walkers, replacing them with unmap_vm_area().\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] ppc64: pgtable.h and other header cleanups\n\nThis patch started as simply removing a few never-used macros from\nasm-ppc64/pgtable.h, then kind of grew.  It now makes a bunch of\ncleanups to the ppc64 low-level header files (with corresponding\nchanges to .c files where necessary) such as:\n\t- Abolishing never-used macros\n\t- Eliminating multiple #defines with the same purpose\n\t- Removing pointless macros (cases where just expanding the\nmacro everywhere turns out clearer and more sensible)\n\t- Removing some cases where macros which could be defined in\nterms of each other weren\u0027t\n\t- Moving imalloc() related definitions from pgtable.h to their\nown header file (imalloc.h)\n\t- Re-arranging headers to group things more logically\n\t- Moving all VSID allocation related things to mmu.h, instead\nof being split between mmu.h and mmu_context.h\n\t- Removing some reserved space for flags from the PMD - we\u0027re\nnot using it.\n\t- Fix some bugs which broke compile with STRICT_MM_TYPECHECKS.\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
