0509ad5 Bjorn Helgaas 11 March 2008, 21:24:41 UTC PNP: disable PNP motherboard resources that overlap PCI BARs Some BIOSes have PNP motherboard devices with resources that partially overlap PCI BARs. The PNP system driver claims these motherboard resources, which prevents the normal PCI driver from requesting them later. This patch disables the PNP resources that conflict with PCI BARs so they won't be claimed by the PNP system driver. Of course, this only works if PCI devices have already been enumerated. Currently this is the case because PCI devices are discovered before any PNP init via this path: acpi_pci_root_init() -> acpi_pci_root_add() -> pci_acpi_scan_root() -> pci_scan_bus_parented() -> pci_scan_child_bus() -> ... Avuton Olrich tested this and confirmed that it fixes his ALSA sound card (see http://lkml.org/lkml/2008/1/27/168).

0738c4b Paul Mundt 12 March 2008, 07:51:31 UTC nommu: Provide is_vmalloc_addr() stub. Introduced in commit-id 9e2779fa281cfda13ac060753d674bbcaa23367e and ifdef'ed out for nommu in 8ca3ed87db062201e1fa15b64a9214e193fc3a8a, both approaches end up breaking the nommu build in different ways. An impressive feat for a 2-liner. Current is_vmalloc_addr() users fall in to two camps: - Determining whether to use vfree()/kfree() - Whether to do vmlist traversal (only /proc/kcore). Since we don't support /proc/kcore on nommu, that leaves the vfree()/kfree() determination use cases. nommu vfree() happens to be a wrapper to kfree() anyways, so is_vmalloc_addr() can always return 0 and end up with the right behaviour.

985a34b Thomas Gleixner 09 March 2008, 12:14:37 UTC x86: remove quicklists quicklists cause a serious memory leak on 32-bit x86, as documented at: http://bugzilla.kernel.org/show_bug.cgi?id=9991 the reason is that the quicklist pool is a special-purpose cache that grows out of proportion. It is not accounted for anywhere and users have no way to even realize that it's the quicklists that are causing RAM usage spikes. It was supposed to be a relatively small pool, but as demonstrated by KOSAKI Motohiro, they can grow as large as: Quicklists: 1194304 kB given how much trouble this code has caused historically, and given that Andrew objected to its introduction on x86 (years ago), the best option at this point is to remove them.

40f0933 Roland McGrath 29 February 2008, 03:57:07 UTC x86: ia32 syscall restart fix The code to restart syscalls after signals depends on checking for a negative orig_ax, and for particular negative -ERESTART* values in ax. These fields are 64 bits and for a 32-bit task they get zero-extended. The syscall restart behavior is lost, a regression from a native 32-bit kernel and from 64-bit tasks' behavior. This patch fixes the problem by doing sign-extension where it matters. For orig_ax, the only time the value should be -1 but winds up as 0x0ffffffff is via a 32-bit ptrace call. So the patch changes ptrace to sign-extend the 32-bit orig_eax value when it's stored; it doesn't change the checks on orig_ax, though it uses the new current_syscall() inline to better document the subtle importance of the used of signedness there. The ax value is stored a lot of ways and it seems hard to get them all sign-extended at their origins. So for that, we use the current_syscall_ret() to sign-extend it only for 32-bit tasks at the time of the -ERESTART* comparisons.

08f503b Gregory Haskins 10 March 2008, 21:59:11 UTC keep rd->online and cpu_online_map in sync It is possible to allow the root-domain cache of online cpus to become out of sync with the global cpu_online_map. This is because we currently trigger removal of cpus too early in the notifier chain. Other DOWN_PREPARE handlers may in fact run and reconfigure the root-domain topology, thereby stomping on our own offline handling. The end result is that rd->online may become out of sync with cpu_online_map, which results in potential task misrouting. So change the offline handling to be more tightly coupled with the global offline process by triggering on CPU_DYING intead of CPU_DOWN_PREPARE.

f5dbb55 Ingo Molnar 10 March 2008, 17:04:34 UTC fix BIOS PCI config cycle buglet causing ACPI boot regression I figured out another ACPI related regression today. randconfig testing triggered an early boot-time hang on a laptop of mine (32-bit x86, config attached) - the screen was scrolling ACPI AML exceptions [with no serial port and no early debugging available]. v2.6.24 works fine on that laptop with the same .config, so after a few hours of bisection (had to restart it 3 times - other regressions interacted), it honed in on this commit: | 10270d4838bdc493781f5a1cf2e90e9c34c9142f is first bad commit | | Author: Linus Torvalds <torvalds@woody.linux-foundation.org> | Date: Wed Feb 13 09:56:14 2008 -0800 | | acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read() reverting this commit ontop of -rc5 gave a correctly booting kernel. But this commit fixes a real bug so the real question is, why did it break the bootup? After quite some head-scratching, the following change stood out: - pci_id->bus = tu8; + pci_id->bus = val; pci_id->bus is defined as u16: struct acpi_pci_id { u16 segment; u16 bus; ... and 'tu8' changed from u8 to u32. So previously we'd unconditionally mask the return value of acpi_os_read_pci_configuration() (raw_pci_read()) to 8 bits, but now we just trust whatever comes back from the PCI access routines and only crop it to 16 bits. But if the high 8 bits of that result contains any noise then we'll write that into ACPI's PCI ID descriptor and confuse the heck out of the rest of ACPI. So lets check the PCI-BIOS code on that theory. We have this codepath for 8-bit accesses (arch/x86/pci/pcbios.c:pci_bios_read()): switch (len) { case 1: __asm__("lcall *(%%esi); cld\n\t" "jc 1f\n\t" "xor %%ah, %%ah\n" "1:" : "=c" (*value), "=a" (result) : "1" (PCIBIOS_READ_CONFIG_BYTE), "b" (bx), "D" ((long)reg), "S" (&pci_indirect)); Aha! The "=a" output constraint puts the full 32 bits of EAX into *value. But if the BIOS's routines set any of the high bits to nonzero, we'll return a value with more set in it than intended. The other, more common PCI access methods (v1 and v2 PCI reads) clear out the high bits already, for example pci_conf1_read() does: switch (len) { case 1: *value = inb(0xCFC + (reg & 3)); which explicitly converts the return byte up to 32 bits and zero-extends it. So zero-extending the result in the PCI-BIOS read routine fixes the regression on my laptop. ( It might fix some other long-standing issues we had with PCI-BIOS during the past decade ... ) Both 8-bit and 16-bit accesses were buggy.

21bbb39 Paul E. McKenney 10 March 2008, 18:43:57 UTC rcu: move PREEMPT_RCU config option back under PREEMPT The original preemptible-RCU patch put the choice between classic and preemptible RCU into kernel/Kconfig.preempt, which resulted in build failures on machines not supporting CONFIG_PREEMPT. This choice was therefore moved to init/Kconfig, which worked, but placed the choice between classic and preemptible RCU at the top level, a very obtuse choice indeed. This patch changes from the Kconfig "choice" mechanism to a pair of booleans, only one of which (CONFIG_PREEMPT_RCU) is user-visible, and is located in kernel/Kconfig.preempt, where one would expect it to be. The other (CONFIG_CLASSIC_RCU) is in init/Kconfig so that it is available to all architectures, hopefully avoiding build breakage. Thanks to Roman Zippel for suggesting this approach.

Sometimes, e.g. during forward-porting mistakes happen and buggy module created, where result of comparison "workqueue != NULL" is propagated all the way up to sys_init_module. What happens is that some other module created workqueue in question, our module created it again and module was successfully loaded. Or it could be some other bug. Let's make such mistakes much more visible. In retrospective, such messages would noticeably shorten some of my head-scratching sessions. Note, that dump_stack() is just a way to get attention from user. Sample message: sys_init_module: 'foo'->init suspiciously returned 1, it should follow 0/-E convention sys_init_module: loading module anyway...

2668db9 Adam Litke 10 March 2008, 18:43:50 UTC hugetlb: correct page count for surplus huge pages Free pages in the hugetlb pool are free and as such have a reference count of zero. Regular allocations into the pool from the buddy are "freed" into the pool which results in their page_count dropping to zero. However, surplus pages can be directly utilized by the caller without first being freed to the pool. Therefore, a call to put_page_testzero() is in order so that such a page will be handed to the caller with a correct count. This has not affected end users because the bad page count is reset before the page is handed off. However, under CONFIG_DEBUG_VM this triggers a BUG when the page count is validated. Thanks go to Mel for first spotting this issue and providing an initial fix.

69682d8 Lee Schermerhorn 10 March 2008, 18:43:45 UTC mempolicy: fix reference counting bugs Address 3 known bugs in the current memory policy reference counting method. I have a series of patches to rework the reference counting to reduce overhead in the allocation path. However, that series will require testing in -mm once I repost it. 1) alloc_page_vma() does not release the extra reference taken for vma/shared mempolicy when the mode == MPOL_INTERLEAVE. This can result in leaking mempolicy structures. This is probably occurring, but not being noticed. Fix: add the conditional release of the reference. 2) hugezonelist unconditionally releases a reference on the mempolicy when mode == MPOL_INTERLEAVE. This can result in decrementing the reference count for system default policy [should have no ill effect] or premature freeing of task policy. If this occurred, the next allocation using task mempolicy would use the freed structure and probably BUG out. Fix: add the necessary check to the release. 3) The current reference counting method assumes that vma 'get_policy()' methods automatically add an extra reference a non-NULL returned mempolicy. This is true for shmem_get_policy() used by tmpfs mappings, including regular page shm segments. However, SHM_HUGETLB shm's, backed by hugetlbfs, just use the vma policy without the extra reference. This results in freeing of the vma policy on the first allocation, with reuse of the freed mempolicy structure on subsequent allocations. Fix: Rather than add another condition to the conditional reference release, which occur in the allocation path, just add a reference when returning the vma policy in shm_get_policy() to match the assumptions.

e82cc12 David Brownell 07 March 2008, 21:49:42 UTC USB: fix ehci unlink regressions The recent EHCI driver update to split the IAA watchdog timer out from the other timers made several things work better, but not everything; and it created a couple new issues in bugzilla. Ergo this patch: - Handle a should-be-rare SMP race between the watchdog firing and (very late) IAA interrupts; - Remove a shouldn't-have-been-added WARN_ON() test; - Guard against one observed OOPS; - If this watchdog fires during clean HC shutdown, it should act as a NOP instead of interfering with the shutdown sequence; - Guard against silicon errata hypothesized by some vendors: * IAA status latch broken, but IAAD cleared OK; * IAAD wasn't cleared when IAA status got reported; The WARN_ON is in bugzilla as 10168; the OOPS as 10078; these are both regressions.

b91aac2 Jesper Juhl 08 March 2008, 01:16:07 UTC PCI Hotplug: Fix small mem leak in IBM Hot Plug Controller Driver In drivers/pci/hotplug/ibmphp_ebda.c::ebda_rsrc_controller(), storage is allocated with kzalloc() and assigned to 'tmp_slot'. Then lots of stuff, like ->flag, ->supported_speed etc is set in tmp_slot. A bit further down there's then this test : if (!bus_info_ptr1) { rc = -ENODEV; goto error; } At this point, tmp_slot has not been assigned to anything, so when erroring-out we want to free it, but nothing at the 'error:' label free's 'tmp_slot' - and we can't really free 'tmp_slot' at 'error:' since we may jump to that label later when 'tmp_slot' *has* been used and we do not want it freed. So, the only sane option left seems to be to kfree(tmp_slot) just before jumping to the 'error:' label in the one place where this is what actually makes sense. The following patch does just that and thus kills off a tiny potential memory leak.

It is used to *define* tables, not to declare them. It should be called DEFINE_PCI_DEVICE_TABLE. b) It's lame, anyway. We could implement any number of such helper thingies, but we choose not to.

e88a0c2 James Bottomley 09 March 2008, 16:57:56 UTC drivers: fix dma_get_required_mask There's a bug in the current implementation of dma_get_required_mask() where it ands the returned mask with the current device mask. This rather defeats the purpose if you're using the call to determine what your mask should be (since you will at that time have the default DMA_32BIT_MASK). This bug results in any driver that uses this function *always* getting a 32 bit mask, which is wrong. Fix by removing the and with dev->dma_mask.

1ef36fa Paul Bolle 10 March 2008, 15:39:03 UTC lguest: Do not append space to guests kernel command line The lguest launcher appends a space to the kernel command line (if kernel arguments are specified on its command line). This space is unneeded. More importantly, this appended space will make Red Hat's nash script interpreter (used in a Fedora style initramfs) add an empty argument to init's command line. This empty argument will make kernel arguments like "init=/bin/bash" fail (because the shell will try to execute a script with an empty name). This could be considered a bug in nash, but is easily fixed in the lguest launcher too.

Ahmed managed to crash the Host in release_pgd(), which cannot be a Guest bug, and indeed it wasn't. The bug was that handing a 0 as the address of the toplevel page table being manipulated can cause the lookup code in find_pgdir() to return an uninitialized cache entry (we shadow up to 4 top level page tables for each Guest). Commit 37cc8d7f963ba2deec29c9b68716944516a3244f introduced this behaviour in the Guest, uncovering the bug. The patch which he submitted (which removed the /4 from the index calculation) simply ensured that these high-indexed entries hit the early exit path of guest_set_pmd(). But you get lots of segfaults in guest userspace as the PMDs aren't being updated. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 10 March 2008, 22:35:58 UTC
