Pull GFS2 updates from Steven Whitehouse: "The major feature this time is the "rbm" conversion in the resource group code. The new struct gfs2_rbm specifies the location of an allocatable block in (resource group, bitmap, offset) form. There are a number of added helper functions, and later patches then rewrite some of the resource group code in terms of this new structure. Not only does this give us a nice code clean up, but it also removes some of the previous restrictions where extents could not cross bitmap boundaries, for example. In addition to that, there are a few bug fixes and clean ups, but the rbm work is by far the majority of this patch set in terms of number of changed lines." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: (27 commits) GFS2: Write out dirty inode metadata in delayed deletes GFS2: fix s_writers.counter imbalance in gfs2_ail_empty_gl GFS2: Fix infinite loop in rbm_find GFS2: Consolidate free block searching functions GFS2: Get rid of I_MUTEX_QUOTA usage GFS2: Stop block extents at the end of bitmaps GFS2: Fix unclaimed_blocks() wrapping bug and clean up GFS2: Improve block reservation tracing GFS2: Fall back to ignoring reservations, if there are no other blocks left GFS2: Fix ->show_options() for statfs slow GFS2: Use rbm for gfs2_setbit() GFS2: Use rbm for gfs2_testbit() GFS2: Eliminate unnecessary check for state > 3 in bitfit GFS2: Eliminate redundant calls to may_grant GFS2: Combine functions gfs2_glock_dq_wait and wait_on_demote GFS2: Combine functions gfs2_glock_wait and wait_on_holder GFS2: inline __gfs2_glock_schedule_for_reclaim GFS2: change function gfs2_direct_IO to use a normal gfs2_glock_dq GFS2: rbm code cleanup GFS2: Fix case where reservation finished at end of rgrp ...

2012-09-29vfs: dcache: fix deadlock in tree traversalMiklos Szeredi1-0/+6
IBM reported a deadlock in select_parent(). This was found to be caused by taking rename_lock when already locked when restarting the tree traversal. There are two cases when the traversal needs to be restarted: 1) concurrent d_move(); this can only happen when not already locked, since taking rename_lock protects against concurrent d_move(). 2) racing with final d_put() on child just at the moment of ascending to parent; rename_lock doesn't protect against this rare race, so it can happen when already locked. Because of case 2, we need to be able to handle restarting the traversal when rename_lock is already held. This patch fixes all three callers of try_to_ascend(). IBM reported that the deadlock is gone with this patch. [ I rewrote the patch to be smaller and just do the "goto again" if the lock was already held, but credit goes to Miklos for the real work. - Linus ] Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Cc: Al Viro <viro@ZenIV.linux.org.uk> Cc: stable@vger.kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-09-28mtdchar: fix offset overflow detectionLinus Torvalds1-6/+42
Sasha Levin has been running trinity in a KVM tools guest, and was able to trigger the BUG_ON() at arch/x86/mm/pat.c:279 (verifying the range of the memory type). The call trace showed that it was mtdchar_mmap() that created an invalid remap_pfn_range(). The problem is that mtdchar_mmap() does various really odd and subtle things with the vma page offset etc, and uses the wrong types (and the wrong overflow) detection for it. For example, the page offset may well be 32-bit on a 32-bit architecture, but after shifting it up by PAGE_SHIFT, we need to use a potentially 64-bit resource_size_t to correctly hold the full value. Also, we need to check that the vma length plus offset doesn't overflow before we check that it is smaller than the length of the mtdmap region. This fixes things up and tries to make the code a bit easier to read.

2012-09-28iommu/amd: Fix wrong assumption in iommu-group specific codeJoerg Roedel1-2/+4
The new IOMMU groups code in the AMD IOMMU driver makes the assumption that there is a pci_dev struct available for all device-ids listed in the IVRS ACPI table. Unfortunatly this assumption is not true and so this code causes a NULL pointer dereference at boot on some systems. Fix it by making sure the given pointer is never NULL when passed to the group specific code. The real fix is larger and will be queued for v3.7.

2012-09-27qlcnic: Fix scheduling while atomic bugNarendra K1-2/+2
In the device close path, 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' call msleep. But 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock held resulting in scheduling while atomic bug causing the following trace. I observed that the commit 012dc19a45b2b9cc2ebd14aaa401cf782c2abba4 from John Fastabend addresses a similar issue in ixgbevf driver. Adopting the same approach used in the commit, this patch uses mdelay to address the issue.

2012-09-27um: Preinclude include/linux/kern_levels.hGeert Uytterhoeven4-14/+12
The userspace part of UML uses the asm-offsets.h generator mechanism to create definitions for UM_KERN_<LEVEL> that match the in-kernel KERN_<LEVEL> constant definitions. As of commit 04d2c8c83d0e3ac5f78aeede51babb3236200112 ("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e. it contains two parts. However, the combo of DEFINE_STR() in arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't support string literals consisting of multiple parts. Hence for all UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual definition, while the remainder ends up in the comment. E.g. in include/generated/asm-offsets.h we get #define UM_KERN_INFO "\001" /* "6" KERN_INFO */ instead of #define UM_KERN_INFO "\001" "6" /* KERN_INFO */ This causes spurious '^A' output in some kernel messages: Calibrating delay loop... 4640.76 BogoMIPS (lpj=23203840) pid_max: default: 32768 minimum: 301 Mount-cache hash table entries: 256 ^AChecking that host ptys support output SIGIO...Yes ^AChecking that host ptys support SIGIO on close...No, enabling workaround ^AUsing 2.6 host AIO NET: Registered protocol family 16 bio: create slab <bio-0> at 0 Switching to clocksource itimer To fix this: - Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from arch/um/include/shared/common-offsets.h to arch/um/include/shared/user.h, which is preincluded for all userspace parts, - Preinclude include/linux/kern_levels.h for all userspace parts, to obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't violate the kernel/userspace separation, as include/linux/kern_levels.h is self-contained and doesn't expose any other kernel internals. - Remove the now unused STR() and DEFINE_STR() macros.

2012-09-27USB: Fix race condition when removing host controllersAlan Stern2-5/+3
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file. The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops. The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

ohci-at91: fix PIO handling in relation with number of ports) started setting unused pins to EINVAL. But this exposed a bug in the ohci_hcd_at91_overcurrent_irq function where the gpio was used without being checked to see if it is valid. This patches fixed the issue by adding the gpio valid check.

2012-09-27um: kill thread->forkingAl Viro7-66/+29
we only use that to tell copy_thread() done by syscall from that done by kernel_thread(). However, it's easier to do simply by checking PF_KTHREAD in thread flags. Merge sys_clone() guts for 32bit and 64bit, while we are at it... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-09-27md/raid10: fix "enough" function for detecting if array is failed.NeilBrown1-3/+5
The 'enough' function is written to work with 'near' arrays only in that is implicitly assumes that the offset from one 'group' of devices to the next is the same as the number of copies. In reality it is the number of 'near' copies. So change it to make this number explicit. This bug makes it possible to run arrays without enough drives present, which is dangerous. It is appropriate for an -stable kernel, but will almost certainly need to be modified for some of them.

2012-09-27drm/nvc0/fifo: ignore bits in PFIFO_INTR that aren't set in PFIFO_INTR_ENBen Skeggs2-2/+4
PFIFO_INTR = 0x40000000 appears to be a normal case on nvc0/nve0 PFIFO, the binary driver appears to completely ignore it in its PFIFO interrupt handler and even masks off the bit (as we do) in PFIFO_INTR_EN at init time. The bits still light up in the hardware sometimes though, so lets just ignore any bits we haven't explicitely requested. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
