Pointed out by Linus Torvalds. sys_signal() forgets to initialize ->sa_mask. ( I suspect arch/ia64/ia32/ia32_signal.c:sys32_signal() also needs this fix ) Signed-off-by:

If you set network interface down and up again, the IPv6 address autoconfiguration does not work. 'ip addr' shows that the link-local address is in tentative state. We don't even react to periodical router advertisements. During NETDEV_DOWN we clear IF_READY, and we don't set it back in NETDEV_UP. While starting to perform DAD on the link-local address, we notice that the device is not in IF_READY, and we abort autoconfiguration process (which would eventually send router solicitations).

Unfortunately, the reiserfs_attrs_cleared bit in the superblock flag can lie. File systems have been observed with the bit set, yet still contain garbage in the stat data field, causing unpredictable results. This patch backs out the enable-by-default behavior. It eliminates the changes from: d50a5cd860ce721dbeac6a4f3c6e42abcde68cd8, and ef5e5414e7a83eb9b4295bbaba5464410b11e030. Signed-off-by:

2.6.15's hugepage faulting introduced huge_pages_needed accounting into hugetlbfs: to count how many pages are already in cache, for spot check on how far a new mapping may be allowed to extend the file. But it's muddled: each hugepage found covers HPAGE_SIZE, not PAGE_SIZE. Once pages were already in cache, it would overshoot, wrap its hugepages count backwards, and so fail a harmless repeat mapping with -ENOMEM. Fixes the problem found by Don Dupuis. Signed-off-by:

early_cpu_detect only runs on the BP, but this code needs to run on all CPUs. This will fix problems with the powernow-k8 driver on dual core systems and general misdetection of AMD dual core. Looks like a mismerge somewhere. Also add a warning comment. Signed-off-by:

5dce971a in Linus' tree, otherwise known as bridge-netfilter-races-on-device-removal.patch in 2.5.15.4 removed has_bridge_parent, however this symbol is still called with NETFILTER_DEBUG is enabled. This patch uses the already seeded realoutdev value to detect if a parent exists, and if so, the value of the parent. Signed-Off-By:

sys_shmdt() can manage shm segments which are covered by multiple vmas. (This can happen when a user uses mprotect() after shmat().) This works well if shm is aligned to PAGE_SIZE, but if not, the last segment cannot be detached. It is because a comparison in sys_shmdt() (vma->vm_end - addr) < size addr == return address of shmat() size == shmsize, argments to shmget() size should be aligned to PAGE_SIZE before being compared with vma->vm_end, which is aligned.

In 2.6.14, we had the following definition of _GLOBAL() in include/asm-ppc/processor.h: #define _GLOBAL(n)\ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n;\ n: In 2.6.15, as part of the great powerpc merge, we moved this definition to include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as: #define _GLOBAL(n) \ .text; \ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n; \ n: Mostly, this is fine. However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

e.g. The sx8 driver uses names like sx8/0. This would make a md component dev name like /sys/block/md0/md/dev-sx8/0 which is not allowed. So we change the '/' to '!' just like fs/partitions/check.c(register_disk) does. Signed-off-by:

With the latest 2.6.15 kernel builds for alpha on Debian, we ran into a problem with undefined references to __cmpxchg_called_with_bad_pointer() in a couple of kernel modules (xfs.ko and drm.ko; see http://bugs.debian.org/347556). It looks like people have been trying to out-clever each other wrt the definition of "inline" on this architecture :), with the result that __cmpxchg(), which must be inlined so the compiler can see its argument is const, is not guaranteed to be inlined. Indeed, it was not being inlined when building with -Os. The attached patch fixes the issue by adding an __attribute__((always_inline)) explicitly to the definition of __cmpxchg() instead of relying on redefines of "inline" elsewhere to make this happen.

Don't mark the reference per cpu data init data (so it stays around after boot) and point all impossible CPUs to it. This way they reference some valid - although shared memory. Usually this is only initialization like INIT_LIST_HEADs and there won't be races because these CPUs never run. Still somewhat hackish. Signed-off-by:

When we pull the PPP protocol off the skb, we forgot to update the hardware RX checksum. This may lead to messages such as dsl0: hw csum failure. Similarly, we need to clear the hardware checksum flag when we use the existing packet to store the decompressed result. Signed-off-by:
