      "message": "[POWERPC] Support feature fixups in vdso\u0027s\n\nThis patch reworks the feature fixup mecanism so vdso\u0027s can be fixed up.\nThe main issue was that the construct:\n\n        .long   label  (or .llong on 64 bits)\n\nwill not work in the case of a shared library like the vdso. It will\ngenerate an empty placeholder in the fixup table along with a reloc,\nwhich is not something we can deal with in the vdso.\n\nThe idea here (thanks Alan Modra !) is to instead use something like:\n\n1:\n        .long   label - 1b\n\nThat is, the feature fixup tables no longer contain addresses of bits of\ncode to patch, but offsets of such code from the fixup table entry\nitself. That is properly resolved by ld when building the .so\u0027s. I\u0027ve\nmodified the fixup mecanism generically to use that method for the rest\nof the kernel as well.\n\nAnother trick is that the 32 bits vDSO included in the 64 bits kernel\nneed to have a table in the 64 bits format. However, gas does not\nsupport 32 bits code with a statement of the form:\n\n        .llong  label - 1b  (Or even just .llong label)\n\nThat is, it cannot emit the right fixup/relocation for the linker to use\nto assign a 32 bits address to an .llong field. Thus, in the specific\ncase of the 32 bits vdso built as part of the 64 bits kernel, we are\nusing a modified macro that generates:\n\n        .long   0xffffffff\n        .llong  label - 1b\n\nNote that is assumes that the value is negative which is enforced by\nthe .lds (those offsets are always negative as the .text is always\nbefore the fixup table and gas doesn\u0027t support emiting the reloc the\nother way around).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"

      "message": "[PATCH] powerpc: Consolidate asm compatibility macros\n\nThis patch consolidates macros used to generate assembly for\ncompatibility across different CPUs or configs.  A new header,\nasm-powerpc/asm-compat.h contains the main compatibility macros.  It\nuses some preprocessor magic to make the macros suitable both for use\nin .S files, and in inline asm in .c files.  Headers (bitops.h,\nuaccess.h, atomic.h, bug.h) which had their own such compatibility\nmacros are changed to use asm-compat.h.\n\nppc_asm.h is now for use in .S files *only*, and a #error enforces\nthat.  As such, we\u0027re a lot more careless about namespace pollution\nhere than in asm-compat.h.\n\nWhile we\u0027re at it, this patch adds a call to the PPC405_ERR77 macro in\nfutex.h which should have had it already, but didn\u0027t.\n\nBuilt and booted on pSeries, Maple and iSeries (ARCH\u003dpowerpc).  Built\nfor 32-bit powermac (ARCH\u003dpowerpc) and Walnut (ARCH\u003dppc).\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
