Which in turn is\ncurrently set to 1024 on all supported architectures.\n\nWhile testing ia64 I recently discovered that this value is in fact too\nsmall. The particular setup I was using actually needs 1172 bytes. This\nlead to very tedious failure mode where the tail of one elf note would\noverwrite the head of another if they ended up being alocated sequentially\nby kmalloc, which was often the case.\n\nIt seems to me that a far better approach is to caclculate the size that\nthe area needs to be. This patch does just that.\n\nIf a simpler stop-gap patch for ia64 to be squeezed into 2.6.21(.X) is\nneeded then this should be as easy as making MAX_NOTE_BYTES larger in\narch/asm-ia64/kexec.h. Perhaps 2048 would be a good choice. However, I\nthink that the approach in this patch is a much more robust idea.\n\nAcked-by: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Simon Horman \u003chorms@verge.net.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c587e4a6a4d808fd2a1c4e7fb2d5a3a31e300d23", "tree": "77af76e34786ad795e5df625915fc58bca1a9abc", "parents": [ "3b581f5485c180016a6c36c4c7007e21c53f8a63" ], "author": { "name": "Richard Purdie", "email": "rpurdie@rpsys.net", "time": "Tue Feb 06 21:29:00 2007 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Fri Feb 16 14:37:06 2007 +0000" }, "message": "[ARM] 4137/1: Add kexec support\n\nAdd kexec support to ARM.\n\nImprovements like commandline handling could be made but this patch gives\nbasic functional support.
