reiserfs_cache_default_acl() should return whether we successfully found the acl or not. We have to return correct value even if reiserfs_get_acl() returns error code and not just 0. Otherwise callers such as reiserfs_mkdir() can unnecessarily lock the xattrs and later functions such as reiserfs_new_inode() fail to notice that we have already taken the lock and try to take it again with obvious consequences.

from: Greg Howard <ghoward@sgi.com> Fix Altix system controller (snsc) device names to include the slot number of the blade whose associated system controller is the target of the device interface. Including the slot number avoids a problem we're currently having where slots within the same enclosure are attempting to create multiple kobjects with identical names. Signed-off-by:

We do this by removing a micro-optimization that tries to avoid grabbing the iommu_bitmap_lock spinlock and using a bus-locked operation. This still races with other simultaneous alloc_iommu or free_iommu(size > 1) which both use bus-unlocked operations. The end result of this race is eventually ending up with an iommu_gart_bitmap that has bits errornously set all over, making large contiguous iommu space allocations fail with 'PCI-DMA: Out of IOMMU space'.

This quietens warnings and actually fixes a bug. The unwind tables would come out wrong without -32, causing pthread cancellation during them to crash in the gcc runtime. The problem seems to only happen with newer binutils (it doesn't happen with 2.16.91.0.2 but happens wit 2.16.91.0.5) Thanks to David Altobelli <david.altobelli@hp.com> and Brian Baker <Brian.B@hp.com> for test case and initial analysis.

Basic problem: pages of a shared memory segment can only be migrated once. In 2.6.16 through 2.6.17-rc1, shared memory mappings do not have a migratepage address space op. Therefore, migrate_pages() falls back to default processing. In this path, it will try to pageout() dirty pages. Once a shared memory page has been migrated it becomes dirty, so migrate_pages() will try to page it out. However, because the page count is 3 [cache + current + pte], pageout() will return PAGE_KEEP because is_page_cache_freeable() returns false. This will abort all subsequent migrations. This patch adds a migratepage address space op to shared memory segments to avoid taking the default path. We use the "migrate_page()" function because it knows how to migrate dirty pages. This allows shared memory segment pages to migrate, subject to other conditions such as # pte's referencing the page [page_mapcount(page)], when requested. I think this is safe. If we're migrating a shared memory page, then we found the page via a page table, so it must be in memory. Can be verified with memtoy and the shmem-mbind-test script, both available at: http://free.linux.hp.com/~lts/Tools/Signed-off-by:

Fix a possible Oops in the Siemens Gigaset base driver when the device is unplugged while an ISDN connection is still active, and makes sure that the isdn4linux link level (LL) is properly informed if a connection is broken by the USB cable being unplugged. - Avoid unsafe checks of URB status fields outside the URB completion handlers, keep track of in-use URBs myself instead. - If an isochronous transfer URB completes with status==0, also check the status of the frame descriptors. - Verify length of interrupt messages received from the device. - Align the length limit on transmitted AT commands with the device documentation. - In case of AT response receive overrun, keep newly arrived instead of old unread data. - Remove redundant check of device ID in the USB probe function. - Correct and improve some comments and formatting.

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu. Signed-off-by:

Patch from Lennert Buytenhek The irq2gpio array was recently converted from an array of ints to an array of chars (by patch 3368/1.) However, this array contains elements that are -1, and on ARM, the char type is unsigned by default, so this patch broke the GPIO check in ixp4xx_set_irq_type. Change the 'char' to be a 'signed char' to fix this. Signed-off-by:

AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes. This was actually documented by AMD, but nobody recognized it as being different from Intel before. The fix first adds an optimization: instead of unconditionally calling FNCLEX after each FXSAVE test if ES is pending and skip it when not needed. Then do a x87 load from a kernel variable to clear FOP/FIP/FDP. This means other processes always will only see a constant value defined by the kernel in their FP state. I took some pain to make sure to chose a variable that's already in L1 during context switch to make the overhead of this low. Also alternative() is used to patch away the new code on CPUs who don't need it. Patch for both i386/x86-64. The problem was discovered originally by Jan Beulich. Richard Brunner provided the basic code for the workarounds, with contribution from Jan. This is CVE-2006-1056 Cc: richard.brunner@amd.com Cc: jbeulich@novell.com Signed-off-by:

This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface is non-existent or otherwise doesn't respond to commands but we issue IO anyway. snd_mpu401_uart_cmd now returns an error code that is passed up the stack so that an open() will fail immediately in such cases. Eventually discovered after wine/cxoffice would constantly cause hard lockups on my desktop immediately after loading (emulating Windows too well). Turned out that I'd recently moved my sound cards around and using /dev/sequencer now talks to a sound card with a broken MPU. This second version changes -EFAULT to -EIO and frees open resources on error too. Test booted and seems to work ok. Signed-off-by:

Fix for bug #6395: Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume after the i2c-i801 driver has left the SMBus in PEC mode. The most simple fix is to clear the PEC bit after after every transaction. That's what this driver was doing up to 2.6.15 (inclusive). Thanks to Daniele Gaffuri for the very good report.

On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset and onboard Sound,... ) the BIOS lets you choose "DISABLED" or "AUTO" for the On-Board Sound Device. If you add another PCI-Sound-Card the BIOS disables the on-board device. So far I have a Quirk, that does set the correspondent BIT in the PCI-registers to enable the soundcard. But how to ensure that the code is executed ONLY on excactly this kind of boards (not any other with similar Chipset)? Cc: Jaroslav Kysela <perex@suse.cz> Acked-by:

In cases where a struct kretprobe's *_handler fields are non-NULL, it is possible to cause a system crash, due to the possibility of calls ending up in zombie functions. Documentation clearly states that unused *_handlers should be set to NULL, but kprobe users sometimes fail to do so. Fix it by setting the non-relevant fields of the struct kretprobe to NULL.
