cpumask_of_cpu()\n\nClean up and optimize cpumask_of_cpu(), by sharing all the zero words.\n\nInstead of stupidly generating all possible i\u003d0...NR_CPUS 2^i patterns\ncreating a huge array of constant bitmasks, realize that the zero words\ncan be shared.\n\nIn other words, on a 64-bit architecture, we only ever need 64 of these\narrays - with a different bit set in one single world (with enough zero\nwords around it so that we can create any bitmask by just offsetting in\nthat big array). And then we just put enough zeroes around it that we\ncan point every single cpumask to be one of those things.\n\nSo when we have 4k CPU\u0027s, instead of having 4k arrays (of 4k bits each,\nwith one bit set in each array - 2MB memory total), we have exactly 64\narrays instead, each 8k bits in size (64kB total).\n\nAnd then we just point cpumask(n) to the right position (which we can\ncalculate dynamically). Once we have the right arrays, getting\n\"cpumask(n)\" ends up being:\n\n static inline const cpumask_t *get_cpu_mask(unsigned int cpu)\n {\n const unsigned long *p \u003d cpu_bit_bitmap[1 + cpu % BITS_PER_LONG];\n p -\u003d cpu / BITS_PER_LONG;\n return (const cpumask_t *)p;\n }\n\nThis brings other advantages and simplifications as well:\n\n - we are not wasting memory that is just filled with a single bit in\n various different places\n\n - we don\u0027t need all those games to re-create the arrays in some dense\n format, because they\u0027re already going to be dense enough.\n\nif we compile a kernel for up to 4k CPU\u0027s, \"wasting\" that 64kB of memory\nis a non-issue (especially since by doing this \"overlapping\" trick we\nprobably get better cache behaviour anyway).\n\n[ mingo@elte.hu:\n\n Converted Linus\u0027s mails into a commit.

You can kexec a\n hibernating kernel, save the memory image of original system and shutdown\n the system. When resuming, you restore the memory image of original system\n via ordinary kexec load then jump back.\n\n- Kernel/system debug through making system snapshot. You can make system\n snapshot, jump back, do some thing and make another system snapshot.\n\n- Cooperative multi-kernel/system. With kexec jump, you can switch between\n several kernels/systems quickly without boot process except the first time.\n This appears like swap a whole kernel/system out/in.\n\n- A general method to call program in physical mode (paging turning\n off). This can be used to invoke BIOS code under Linux.\n\nThe following user-space tools can be used with kexec jump:\n\n- kexec-tools needs to be patched to support kexec jump. The patches\n and the precompiled kexec can be download from the following URL:\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\n- makedumpfile with patches are used as memory image saving tool, it\n can exclude free pages from original kernel memory image file. The\n patches and the precompiled makedumpfile can be download from the\n following URL:\n source: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-src_cvs_kh10.tar.bz2\n patches: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-patches_cvs_kh10.tar.bz2\n binary: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile_cvs_kh10\n\n- An initramfs image can be used as the root file system of kexeced\n kernel. An initramfs image built with \"BuildRoot\" can be downloaded\n from the following URL:\n initramfs image: http://khibernation.sourceforge.net/download/release_v10/initramfs/rootfs_cvs_kh10.gz\n All user space tools above are included in the initramfs image.\n\nUsage example of simple hibernation:\n\n1. Compile and install patched kernel with following options selected:\n\nCONFIG_X86_32\u003dy\nCONFIG_RELOCATABLE\u003dy\nCONFIG_KEXEC\u003dy\nCONFIG_CRASH_DUMP\u003dy\nCONFIG_PM\u003dy\nCONFIG_HIBERNATION\u003dy\nCONFIG_KEXEC_JUMP\u003dy\n\n2. Build an initramfs image contains kexec-tool and makedumpfile, or\n download the pre-built initramfs image, called rootfs.gz in\n following text.\n\n3. Prepare a partition to save memory image of original kernel, called\n hibernating partition in following text.\n\n4. Boot kernel compiled in step 1 (kernel A).\n\n5. In the kernel A, load kernel compiled in step 1 (kernel B) with\n /sbin/kexec. The shell command line can be as follow:\n\n /sbin/kexec --load-preserve-context /boot/bzImage --mem-min\u003d0x100000\n --mem-max\u003d0xffffff --initrd\u003drootfs.gz\n\n6. Boot the kernel B with following shell command line:\n\n /sbin/kexec -e\n\n7. The kernel B will boot as normal kexec. In kernel B the memory\n image of kernel A can be saved into hibernating partition as\n follow:\n\n jump_back_entry\u003d`cat /proc/cmdline | tr \u0027 \u0027 \u0027\\n\u0027 | grep kexec_jump_back_entry | cut -d \u0027\u003d\u0027`\n echo $jump_back_entry \u003e kexec_jump_back_entry\n cp /proc/vmcore dump.elf\n\n Then you can shutdown the machine as normal.\n\n8. Boot kernel compiled in step 1 (kernel C). Use the rootfs.gz as\n root file system.\n\n9. In kernel C, load the memory image of kernel A as follow:\n\n /sbin/kexec -l --args-none --entry\u003d`cat kexec_jump_back_entry` dump.elf\n\n10. Jump back to the kernel A as follow:\n\n /sbin/kexec -e\n\n Then, kernel A is resumed.\n\nImplementation point:\n\nTo support jumping between two kernels, before jumping to (executing)\nthe new kernel and jumping back to the original kernel, the devices\nare put into quiescent state, and the state of devices and CPU is\nsaved. After jumping back from kexeced kernel and jumping to the new\nkernel, the state of devices and CPU are restored accordingly. The\ndevices/CPU state save/restore code of software suspend is called to\nimplement corresponding function.\n\nKnown issues:\n\n- Because the segment number supported by sys_kexec_load is limited,\n hibernation image with many segments may not be load.

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.

So I\nCC\u0027ed this to KVM camp. Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added. If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging). It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations.

To prevent\n deadlock, we never grab a per-hash-list lock while holding a kretprobe\n lock.\n\n 3) We can remove used_instances from struct kretprobe, as we can\n track used instances of kretprobe instances using kretprobe hash\n table.\n\nTime duration for kernel compilation (\"make -j 8\") on a 8-way ppc64 system\nwith return probes set on all systemcalls looks like this.\n\ncacheline non-cacheline Un-patched kernel\naligned patch \t aligned patch\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m46.784s 9m54.412s 10m2.450s\nuser 40m5.715s 40m7.142s 40m4.273s\nsys 2m57.754s 2m58.583s 3m17.430s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nTime duration for kernel compilation (\"make -j 8) on the same system, when\nkernel is not probed.\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m26.389s\nuser 40m8.775s\nsys 2m7.283s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nSigned-off-by: Srinivasa DS \u003csrinivasa@in.ibm.com\u003e\nSigned-off-by: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nAcked-by: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: David S.

They aren\u0027t\n\u003e _incorrect_ per se, but they are definitely bad.\n\u003e\n\u003e Why?\n\u003e\n\u003e Using random _TIF_WORK_MASK flags is really impolite for doing\n\u003e \"scheduling\" work. There\u0027s a reason that arch/x86/kernel/entry_32.S\n\u003e special-cases the _TIF_NEED_RESCHED flag: we don\u0027t want to exit out of\n\u003e vm86 mode unnecessarily.\n\u003e\n\u003e See the \"work_notifysig_v86\" label, and how it does that\n\u003e \"save_v86_state()\" thing etc etc.\n\nRight, I never liked having to fiddle with those TIF flags. Initially I\nneeded it because the hrtimer base lock could not nest in the rq lock.\nThat however is fixed these days.\n\nCurrently the only reason left to fiddle with the TIF flags is remote\nwakeups.

These are patterned after the\n node_to_cpumask_ptr macros.\n\n In general terms, if there is a cpumask_of_cpu_map[] then a pointer to\n the cpumask_of_cpu_map[cpu] entry is used. The cpumask_of_cpu_map\n is provided when there is a large NR_CPUS count, reducing\n greatly the amount of code generated and stack space used for\n cpumask_of_cpu(). The pointer to the cpumask_t value is needed for\n calling set_cpus_allowed_ptr() to reduce the amount of stack space\n needed to pass the cpumask_t value.\n\n If there isn\u0027t a cpumask_of_cpu_map[], then a temporary variable is\n declared and filled in with value from cpumask_of_cpu(cpu) as well as\n a pointer variable pointing to this temporary variable. Afterwards,\n the pointer is used to reference the cpumask value.
