This allows us\nto fix the issue in kernel/timer.c (noticed by Balbir) where we could only\nadd an unscaled value to the scaled utime/stime.\n\nThis adds a cputime_to_scaled function. As before, the POWERPC version\ndoes the scaling based on the last SPURR/PURR ratio calculated. The\ngeneric and s390 (only other arch to implement asm/cputime.h) versions are\nboth NOPs.\n\nAlso moves the SPURR and PURR snapshots closer.\n\nSigned-off-by: Michael Neuling \u003cmikey@neuling.org\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5e5419734c8719cbc01af959ad9c0844002c0df5", "tree": "a075dca3f719946689efa0245464855cbf2a20ce", "parents": [ "9f8f2172537de7af0b0fbd33502d18d52b1339bc" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Feb 04 22:29:14 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:18 2008 -0800" }, "message": "add mm argument to pte/pmd/pud/pgd_free\n\n(with Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e)\n\nThe pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as\nfirst argument.

The upside is:\n\n * Providing two features which were \"want to have (but OK to defer)\" when\n GPIO interfaces were first discussed in November 2006:\n\n -\tA \"struct gpio_chip\" to plug in GPIOs that aren\u0027t directly supported\n\tby SOC platforms, but come from FPGAs or other multifunction devices\n\tusing conventional device registers (like UCB-1x00 or SM501 GPIOs,\n\tand southbridges in PCs with more open specs than usual).\n\n -\tFull support for message-based GPIO expanders, where registers are\n\taccessed through sleeping I/O calls. Previous support for these\n\t\"cansleep\" calls was just stubs. (One example: the widely used\n\tpcf8574 I2C chips, with 8 GPIOs each.)\n\n * Including a non-stub implementation of the gpio_{request,free}() calls,\n making those calls much more useful. The diagnostic labels are also\n recorded given DEBUG_FS, so /sys/kernel/debug/gpio can show a snapshot\n of all GPIOs known to this infrastructure.\n\nThe driver programming interfaces introduced in 2.6.21 do not change at all;\nthis infrastructure is entirely below those covers.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nCc: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: Eric Miao \u003ceric.miao@marvell.com\u003e\nCc: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: Philipp Zabel \u003cphilipp.zabel@gmail.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Ben Gardner \u003cbgardner@wabtec.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "795d45b22c079946332bf3825afefe5a981a97b6", "tree": "8952c202b021cb73f3a85988a91dd54724707a0b", "parents": [ "7b610eec7a06ede64f71459e7f412dfd96f4cc5e" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Mon Feb 04 16:48:10 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Feb 04 16:48:10 2008 +0100" }, "message": "x86: fix RTC lockdep warning: potential hardirq recursion\n\nAfter disabling both CONFIG_DEBUG_LOCKING_API_SELFTESTS and netconsole\n(using current mainline) I get a login prompt, and also...\n\n[ 5.181668] SELinux: policy loaded with handle_unknown\u003ddeny\n[ 5.183315] type\u003d1403 audit(1202100038.157:3): policy loaded auid\u003d4294967295 ses\u003d4294967295\n[ 5.822073] SELinux: initialized (dev usbfs, type usbfs), uses genfs_contexts\n[ 7.819146] ------------[ cut here ]------------\n[ 7.819146] WARNING: at kernel/lockdep.c:2033 trace_hardirqs_on+0x9b/0x10d()\n[ 7.819146] Modules linked in: generic ext3 jbd ide_disk ide_core\n[ 7.819146] Pid: 399, comm: hwclock Not tainted 2.6.24 #4\n[ 7.819146] [\u003cc011d140\u003e] warn_on_slowpath+0x41/0x51\n[ 7.819146] [\u003cc01364a9\u003e] ?

It would be great if it could be the default so that we can get\nrid of various forms of DISCONTIG and other variations on memory maps. So far\nwhat has hindered this are the additional lookups that SPARSEMEM introduces\nfor virt_to_page and page_address. This goes so far that the code to do this\nhas to be kept in a separate function and cannot be used inline.\n\nThis patch introduces a virtual memmap mode for SPARSEMEM, in which the memmap\nis mapped into a virtually contigious area, only the active sections are\nphysically backed. This allows virt_to_page page_address and cohorts become\nsimple shift/add operations. No page flag fields, no table lookups, nothing\ninvolving memory is required.\n\nThe two key operations pfn_to_page and page_to_page become:\n\n #define __pfn_to_page(pfn) (vmemmap + (pfn))\n #define __page_to_pfn(page) ((page) - vmemmap)\n\nBy having a virtual mapping for the memmap we allow simple access without\nwasting physical memory. As kernel memory is typically already mapped 1:1\nthis introduces no additional overhead. The virtual mapping must be big\nenough to allow a struct page to be allocated and mapped for all valid\nphysical pages. This vill make a virtual memmap difficult to use on 32 bit\nplatforms that support 36 address bits.\n\nHowever, if there is enough virtual space available and the arch already maps\nits 1-1 kernel space using TLBs (f.e. true of IA64 and x86_64) then this\ntechnique makes SPARSEMEM lookups even more efficient than CONFIG_FLATMEM.\nFLATMEM needs to read the contents of the mem_map variable to get the start of\nthe memmap and then add the offset to the required entry. vmemmap is a\nconstant to which we can simply add the offset.\n\nThis patch has the potential to allow us to make SPARSMEM the default (and\neven the only) option for most systems. It should be optimal on UP, SMP and\nNUMA on most platforms. Then we may even be able to remove the other memory\nmodels: FLATMEM, DISCONTIG etc.\n\n[apw@shadowen.org: config cleanups, resplit code etc]\n[kamezawa.hiroyu@jp.fujitsu.com: Fix sparsemem_vmemmap init]\n[apw@shadowen.org: vmemmap: remove excess debugging]\n[apw@shadowen.org: simplify initialisation code and reduce duplication]\n[apw@shadowen.org: pull out the vmemmap code into its own file]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \"David S.
