      "message": "kexec jump\n\nThis patch provides an enhancement to kexec/kdump.  It implements the\nfollowing features:\n\n- Backup/restore memory used by the original kernel before/after\n  kexec.\n\n- Save/restore CPU state before/after kexec.\n\nThe features of this patch can be used as a general method to call program in\nphysical mode (paging turning off).  This can be used to call BIOS code under\nLinux.\n\nkexec-tools needs to be patched to support kexec jump. The patches and\nthe precompiled kexec can be download from the following URL:\n\n       source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2\n       patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2\n       binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10\n\nUsage example of calling some physical mode code and return:\n\n1. Compile and install patched kernel with following options selected:\n\nCONFIG_X86_32\u003dy\nCONFIG_KEXEC\u003dy\nCONFIG_PM\u003dy\nCONFIG_KEXEC_JUMP\u003dy\n\n2. Build patched kexec-tool or download the pre-built one.\n\n3. Build some physical mode executable named such as \"phy_mode\"\n\n4. Boot kernel compiled in step 1.\n\n5. Load physical mode executable with /sbin/kexec. The shell command\n   line can be as follow:\n\n   /sbin/kexec --load-preserve-context --args-none phy_mode\n\n6. Call physical mode executable with following shell command line:\n\n   /sbin/kexec -e\n\nImplementation point:\n\nTo support jumping without reserving memory.  One shadow backup page (source\npage) is allocated for each page used by kexeced code image (destination\npage).  When do kexec_load, the image of kexeced code is loaded into source\npages, and before executing, the destination pages and the source pages are\nswapped, so the contents of destination pages are backupped.  Before jumping\nto the kexeced code image and after jumping back to the original kernel, the\ndestination pages and the source pages are swapped too.\n\nC ABI (calling convention) is used as communication protocol between\nkernel and called code.\n\nA flag named KEXEC_PRESERVE_CONTEXT for sys_kexec_load is added to\nindicate that the loaded kernel image is used for jumping back.\n\nNow, only the i386 architecture is supported.\n\nSigned-off-by: Huang Ying \u003cying.huang@intel.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: \"Eric W.

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.

      "message": "[PATCH] kdump: dynamic per cpu allocation of memory for saving cpu registers\n\n- In case of system crash, current state of cpu registers is saved in memory\n  in elf note format.  So far memory for storing elf notes was being allocated\n  statically for NR_CPUS.\n\n- This patch introduces dynamic allocation of memory for storing elf notes.\n  It uses alloc_percpu() interface.  This should lead to better memory usage.\n\n- Introduced based on Andi Kleen\u0027s and Eric W. Biederman\u0027s suggestions.\n\n- This patch also moves memory allocation for elf notes from architecture\n  dependent portion to architecture independent portion.  Now crash_notes is\n  architecture independent.  The whole idea is that size of memory to be\n  allocated per cpu (MAX_NOTE_BYTES) can be architecture dependent and\n  allocation of this memory can be architecture independent.\n\nSigned-off-by: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
