It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "24f1e32c60c45c89a997c73395b69c8af6f0a84e", "tree": "4f30f16e18cb4abbcf96b3b331e6a3f01bfa26e6", "parents": [ "2da3e160cb3d226d87b907fab26850d838ed8d7c" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Sep 09 19:22:48 2009 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sun Nov 08 15:34:42 2009 +0100" }, "message": "hw-breakpoints: Rewrite the hw-breakpoints layer on top of perf events\n\nThis patch rebase the implementation of the breakpoints API on top of\nperf events instances.\n\nEach breakpoints are now perf events that handle the\nregister scheduling, thread/cpu attachment, etc..\n\nThe new layering is now made as follows:\n\n ptrace kgdb ftrace perf syscall\n \\ | / /\n \\ | / /\n /\n Core breakpoint API /\n /\n | /\n | /\n\n Breakpoints perf events\n\n |\n |\n\n Breakpoints PMU ---- Debug Register constraints handling\n (Part of core breakpoint API)\n |\n |\n\n Hardware debug registers\n\nReasons of this rewrite:\n\n- Use the centralized/optimized pmu registers scheduling,\n implying an easier arch integration\n- More powerful register handling: perf attributes (pinned/flexible\n events, exclusive/non-exclusive, tunable period, etc...)\n\nImpact:\n\n- New perf ABI: the hardware breakpoints counters\n- Ptrace breakpoints setting remains tricky and still needs some per\n thread breakpoints references.\n\nTodo (in the order):\n\n- Support breakpoints perf counter events for perf tools (ie: implement\n perf_bpcounter_event())\n- Support from perf tools\n\nChanges in v2:\n\n- Follow the perf \"event \" rename\n- The ptrace regression have been fixed (ptrace breakpoint perf events\n weren\u0027t released when a task ended)\n- Drop the struct hw_breakpoint and store generic fields in\n perf_event_attr.\n- Separate core and arch specific headers, drop\n asm-generic/hw_breakpoint.h and create linux/hw_breakpoint.h\n- Use new generic len/type for breakpoint\n- Handle off case: when breakpoints api is not supported by an arch\n\nChanges in v3:\n\n- Fix broken CONFIG_KVM, we need to propagate the breakpoint api\n changes to kvm when we exit the guest and restore the bp registers\n to the host.\n\nChanges in v4:\n\n- Drop the hw_breakpoint_restore() stub as it is only used by KVM\n- EXPORT_SYMBOL_GPL hw_breakpoint_restore() as KVM can be built as a\n module\n- Restore the breakpoints unconditionally on kvm guest exit:\n TIF_DEBUG_THREAD doesn\u0027t anymore cover every cases of running\n breakpoints and vcpu-\u003earch.switch_db_regs might not always be\n set when the guest used debug registers.\n (Waiting for a reliable optimization)\n\nChanges in v5:\n\n- Split-up the asm-generic/hw-breakpoint.h moving to\n linux/hw_breakpoint.h into a separate patch\n- Optimize the breakpoints restoring while switching from kvm guest\n to host.
