In the\nLinux kernel this breaks ARM, causing most arch/arm/mm/copypage-*.c\nmodules to get miscompiled, resulting in kernel crashes during bootup.\n\nPart of the kernel fix is to augment the __naked function attribute to\nalso imply noinline and noclone. This patch implements that, and has been\nverified to fix boot failures with gcc-4.5 compiled 2.6.34 and 2.6.35-rc1\nkernels.

Basically the current\nRELOC_HIDE can end up trashing r30. Details of the bug can be found at\n\n http://gcc.gnu.org/bugzilla/show_bug.cgi?id\u003d25572\n\nThis bug is present in all compilers before 4.1. It is masked by the\nfact that our current per cpu data code is inefficient and causes\nother loads that end up marking r30 as used.\n\nA workaround identified by Alan Modra is to use the \u003dr asm constraint\ninstead of \u003dg.\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\n[ Verified that this makes no real difference on x86[-64] */\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a1365647022eb05a5993f270a78e9bef3bf554eb", "tree": "6dbcab4db80b7d07fdaec88c003743d1f6e1a289", "parents": [ "fd285bb54d8a3e99810090ae88cfe8ed77d1da25" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Sun Jan 08 01:04:09 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:14:02 2006 -0800" }, "message": "[PATCH] remove gcc-2 checks\n\nRemove various things which were checking for gcc-1.x and gcc-2.x compilers.\n\nFrom: Adrian Bunk \u003cbunk@stusta.de\u003e\n\n Some documentation updates and removes some code paths for gcc \u003c 3.2.\n\nAcked-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
