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.

The rest of this patch consists of code to disable this\nworkaround should this not be the case (with the presumption that\nif a future Itanium processor increases the number of registers, it\nwould also remove the need for this patch).\n\nMove the start of the RBS up to a mod32 boundary to avoid some\ncorner cases.\n\nThe dispatch_illegal_op_fault code outgrew the spot it was\nsquatting in when built with this patch and CONFIG_VIRT_CPU_ACCOUNTING\u003dy\nMove it out to the end of the ivt.\n\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "f52111b1546943545e67573c4dde1c7613ca33d3", "tree": "f8188dd12f7dc78f0f4c26702a5ba0ceea8199c7", "parents": [ "f26a3988917913b3d11b2bd741601a2c64ab9204" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 08 18:19:16 2008 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri May 16 17:22:20 2008 -0400" }, "message": "[PATCH] take init_files to fs/file.c\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "3fb2c74ee20b77affd494c6b8ce7928d0ebbb62e", "tree": "f349e016efe512dd7bdb06b619bc0d1c9f46b35b", "parents": [ "7af1d7532b6cf905230c72c67ad85a480b122374" ], "author": { "name": "Prarit Bhargava", "email": "prarit@redhat.com", "time": "Wed May 14 12:00:24 2008 -0400" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Wed May 14 16:00:14 2008 -0700" }, "message": "[IA64] Properly unregister legacy interrupts\n\nacpi_unregister_gsi() should \"undo\" what acpi_register_gsi() does.\n\nOn systems that have legacy interrupts, acpi_unregister_gsi erroneously calls\niosapci_unregister_intr() which is wrong to do and causes a loud warning.\n\nacpi_unregister_gsi() should just return in these cases.\n\nSigned-off-by: Prarit Bhargava \u003cprarit@redhat.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "7af1d7532b6cf905230c72c67ad85a480b122374", "tree": "ea36fc6f8b6f63b1b182eb0b243163846f47011e", "parents": [ "0fb232fdb2a2674003ef4b874034e872b7256aa9" ], "author": { "name": "Simon Holm Thøgersen", "email": "odie@cs.aau.dk", "time": "Mon May 12 17:40:50 2008 +0200" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Wed May 14 15:58:27 2008 -0700" }, "message": "[IA64] Remove NULL pointer check for argument never passed as NULL.\n\nThere is only palinfo_handle_smp as (indirect) user of palinfo_smp_call (by\nway of smp_call_function_single) and surely palinfo_handle_smp never pass\nNULL as parameter for info.\n\nSigned-off-by: Simon Holm Thøgersen \u003codie@cs.aau.dk\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "0fb232fdb2a2674003ef4b874034e872b7256aa9", "tree": "1b2510c3a38ee21e0007f924b373fb2939089425", "parents": [ "2e513fe4903c62450a9f8c3759f75bc4cd7e4dfd" ], "author": { "name": "Hidetoshi Seto", "email": "seto.hidetoshi@jp.fujitsu.com", "time": "Fri May 09 15:27:09 2008 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Wed May 14 15:56:34 2008 -0700" }, "message": "[IA64] trivial cleanup for perfmon.c\n\nFix a typo, and coding style cleanups for pfm_handle_work().\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "2e513fe4903c62450a9f8c3759f75bc4cd7e4dfd", "tree": "43edb395890cecd8a489961263e52e1c6d2196e5", "parents": [ "3633c7308005e8c1dab594f69ef904424f8b639a" ], "author": { "name": "Hidetoshi Seto", "email": "seto.hidetoshi@jp.fujitsu.com", "time": "Fri May 09 15:26:51 2008 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Wed May 14 15:56:09 2008 -0700" }, "message": "[IA64] trivial cleanup for entry.S\n\nThis patch does:\n -

So in this machine configuration, the crashkernel will be reserved\nabove 4 GB.\n\nFor machines that use SWIOTLB implementation because they lack an I/O MMU\nthe low memory is required by the SWIOTLB implementation. In that case,\nit doesn\u0027t make sense to reserve the crashkernel at all because it\u0027s unusable\nfor kdump.\n\nA special case is the \"hpzx1\" machine vector. In theory, it has a I/O MMU, so\nit can be booted above 4 GB. However, in the kdump case that is not possible\nbecause of changeset 51b58e3e26ebfb8cd56825c4b396ed251f51dec9:\n\n On HP zx1 machines, the \u0027machvec\u003ddig\u0027 parameter is needed for the kdump\n kernel to avoid problems with the HP sba iommu. The problem is that during\n the boot of the kdump kernel, the iommu is re-initialized, so in-flight DMA\n from improperly shutdown drivers causes an IOTLB miss which leads to an\n MCA. With kdump, the idea is to get into the kdump kernel with as little\n code as we can, so shutting down drivers properly is not an option.\n\n The workaround is to add \u0027machvec\u003ddig\u0027 to the kdump kernel boot parameters.\n This makes the kdump kernel avoid using the sba iommu altogether, leaving\n the IOTLB intact. Any ongoing DMA falls harmlessly outside the kdump\n kernel. After the kdump kernel reboots, all devices will have been\n shutdown properly and DMA stopped.\n\nThis patch pushes that functionality into the sba iommu initialization\ncode, so that users won\u0027t have to find the obscure documentation telling\nthem about \u0027machvec\u003ddig\u0027.\n\nThis means that also for hpzx1 it\u0027s not possible to boot when all\nmemory is above the 4 GB limit. So the only machine vectors that can handle\nthis case are \"sn2\" and \"uv\".\n\nSigned-off-by: Bernhard Walle \u003cbwalle@suse.de\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "2224661494278bfc1c35b392cf6ee6f58e1d5e64", "tree": "1a0bd165aedfd28191a017901490c5bf3fd9f328", "parents": [ "7868f1ed84696d3cca83558e8dd459f20a36d077" ], "author": { "name": "Jack Steiner", "email": "steiner@sgi.com", "time": "Tue May 06 15:18:57 2008 -0500" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Wed May 14 14:22:04 2008 -0700" }, "message": "[IA64] machvec support for SGI UV platform\n\nThis patch adds the basic IA64 machvec infrastructure to support\nthe SGI \"UV\" platform.\n\nSigned-off-by: Jack Steiner \u003csteiner@sgi.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "f8e811b98935f702b48abc92563462a15c226eb8", "tree": "5446de054b7d168c118783df77577f14d4055d81", "parents": [ "848376c774a941c29e4fa083d96d84a5f2190857" ], "author": { "name": "Al Viro", "email": "viro@ftp.linux.org.uk", "time": "Thu May 01 14:36:36 2008 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu May 01 14:36:36 2008 -0700" }, "message": "[IA64] fix file and descriptor handling in perfmon\n\nRaces galore...
