Absolute alignment requirements may never be applied to node-relative offsets. Andreas Herrmann spotted this flaw when a bootmem allocation on an unaligned node was itself not aligned because the combination of an unaligned node with an aligned offset into that node is not garuanteed to be aligned itself. This patch introduces two helper functions that align a node-relative index or offset with respect to the node's starting address so that the absolute PFN or virtual address that results from combining the two satisfies the requested alignment. Then all the broken ALIGN()s in alloc_bootmem_core() are replaced by these helpers. Signed-off-by:

With commit 5ad31a57 ("rtc: remove BKL for ioctl()"), RTC_UIE_ON ioctl cause double lock on rtc->ops_lock. The ops_lock must not be held while set_uie() calls rtc_read_time() which takes the lock. Also clear_uie() does not need ops_lock. This patch fixes return value of RTC_UIE_OFF ioctl too. Signed-off-by:

In case the binfmt_misc binary handler is registered *before* the e.g. script one (when for example being compiled as a module) the following situation may occur: 1. user launches a script, whose interpreter is a misc binary; 2. the load_misc_binary sets the misc_bang and returns -ENOEVEC, since the binary is a script; 3. the load_script_binary loads one and calls for search_binary_hander to run the interpreter; 4. the load_misc_binary is called again, but refuses to load the binary due to misc_bang bit set. The fix is to move the misc_bang setting lower - prior to the actual call to the search_binary_handler.

Add a comment to s390's page_test_dirty/page_clear_dirty/page_set_dirty dance in page_remove_rmap(): I was wrong to think the PageSwapCache test could be avoided, and would like a comment in there to remind me. And mention s390, to help us remember that this block is not really common. Also move down the "It would be tidy to reset PageAnon" comment: it does not belong to s390's block, and it would be unwise to reset PageAnon before we're done with testing it. Signed-off-by:

I won't say 'fix', because they still look broken, although this will at least allow 'make ARCH=CRIS headers_install' to _complete_. For headers which are exported, we should probably choose between asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't rely on a generated symlink. And we certainly can't export an arch/ directory which doesn't even exist. And the only thing that we seem to include from the arch/ directory is <asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in either arch-v10 or arch-v32 _anyway_. Signed-off-by:

There was another FAT BKL conversion deadlock reported by Bart Trojanowski due to the BKL being used as a recursive lock by FAT, which was missed because it only triggers with 'sync' (or 'dirsync') mounts. The recursion worked for the BKL, but after the conversion to lock_super (which uses a mutex), it just deadlocks. Thanks to Bart for debugging this and testing the fix.

The lock_super() there had been just an automatic conversion of the kernel lock to the superblock lock, but no locking was actually needed there, since the code in fat_write_inode already protected all relevant accesses with a spinlock (sbi->inode_hash_lock to be exact). The only code inside the BKL (and thus the superblock lock) was accesses tp local variables or calls to functions that have long been SMP-safe (i.e. sb_bread, mark_buffe_dirty and brlese). Bart reports: "Looks good. I ran 10 parallel processes creating 1M files truncating them, writing to them again and then deleting them. This patch fixes the issue I ran into.

Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER. Signed-off-by:

sbp2 was too quick to report .update() to the ieee1394 core as failed. (Logged as "Failed to reconnect to sbp2 device!".) The core would then unbind sbp2 from the device. This is not justified if the .update() failed because another bus reset happened. We check this and tell the ieee1394 that .update() succeeded, and the core will call sbp2's .update() for the new bus reset as well. This improves reconnection/re-login especially on buses with several disks as they may issue bus resets in close succession when they come online. Tested by Damien Benoist. Signed-off-by: -

Regression since commit 73cf6023, "ieee1394: use class iteration api": The two loops for (1.) driver updates and (2.) driver probes were replaced by a single loop with bogus needs_probe checks. Hence updates and probes were now intermixed, and especially sbp2 updates (reconnects) held up longer than necessary. While we fix it, change the needs_probe flag to bool type for clarity.
