This will avoid a possible fault in ecryptfs_sync_page(). In the function, eCryptfs calls sync_page() method of a lower filesystem without checking its existence. However, there are many filesystems that don't have this method including network filesystems such as NFS, AFS, and so forth. They may fail when an eCryptfs page is waiting for lock. Signed-off-by:

Dependencies of CONFIG_SUSPEND and CONFIG_HIBERNATION introduced by commit 296699de "Introduce CONFIG_SUSPEND for suspend-to-Ram and standby" are incorrect, as they don't cover the facts that (1) not all architectures support suspend and (2) SMP hibernation is only possible on X86 and PPC64 (if CONFIG_PPC64_SWSUSP is set).

Do not BUG() if we cannot register a slab with sysfs. Just print an error. The only consequence of not registering is that the slab cache is not visible via /sys/slab. A BUG() may not be visible that early during boot and we have had multiple issues here already. Signed-off-by:

Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken. Signed-off-by:

taskstats.ac_exitcode is assigned to task_struct.exit_code in bacct_add_tsk() through the following kernel function calls: do_exit() taskstats_exit() fill_pid() bacct_add_tsk() The problem is that in do_exit(), task_struct.exit_code is set to 'code' only after taskstats_exit() has been called. So we need to move the assignment before taskstats_exit(). Signed-off-by:Jonathan Lim <jlim@sgi.com> Cc: Balbir Singh <balbir@in.ibm.com> Signed-off-by:

Stop UML crashing when trying to dump a process core on x86_64. This is the minimal fix to stop the crash - more things are broken here, and patches are forthcoming. The immediate thing to do is define ELF_CORE_COPY_REGS and ELF_CORE_COPY_FPREGS. Defining ELF_CORE_COPY_FPREGS allows dump_fpu to go away. It is defined in terms of save_fp_registers, so that needs to be added. Signed-off-by:

1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: -

When CONFIG_NET_CLS_ACT is enabled, tc_classify() is called twice in prio_classify(). This causes "interesting" behaviour: with the setup below, packets are duplicated, sent twice to ifb0, and then loop in and out of ifb0. The patch uses the previously calculated return value in the switch, which is probably what Patrick had in mind in commit bdba91ec -- maybe Patrick can double-check this? -- example setup -- ifconfig ifb0 up tc qdisc add dev ifb0 root netem delay 2s tc qdisc add dev $ETH root handle 1: prio tc filter add dev $ETH parent 1: protocol ip prio 10 u32 \ match ip dst 172.24.110.6/32 flowid 1:1 \ action mirred egress redirect dev ifb0 ping -c1 172.24.110.6 Signed-off-by:

Bridge code calls ethtool to get speed. The conversion to using only ethtool_ops broke the case of devices without ethtool_ops. This is a new regression in 2.6.23. Rearranged the switch to a logical order, and use gcc initializer. Ps: speed should have been part of the network device structure from the start rather than burying it in ethtool.

This patch fixes some packet leakage in bridge. The bridging code was allowing forward table entries to be generated even if a device was being blocked. The fix is to not add forwarding database entries unless the port is active. The bug arose as part of the conversion to processing STP frames through normal receive path (in 2.6.17). Signed-off-by:

Alexey Dobriyan reports that maxcpus=1 is still broken in 2.6.23-rc4: if CONFIG_HOTPLUG_CPU is not set, x86_64 bootup oopses in show_stat() - for_each_possible_cpu accesses a per-cpu area which was never set up. Alexey identified commit 61ec7567 (ACPI: boot correctly with "nosmp" or "maxcpus=0") as the origin; but it's not really to blame, just exposes a bug in 2.6.23-rc1's commit 8b3b2955 (Especially when !CONFIG_HOTPLUG_CPU, avoid needlessy allocating resources for CPUs that can never become available). rc1's test for max_cpus < 2 in start_kernel() wasn't working because max_cpus was still NR_CPUS at that point: until rc4 moved the maxcpus parsing earlier. Now it sets cpu_possible_map to 1 before allocating all possible per-cpu areas; then smp_init() expands cpu_possible_map to cpu_present_map (0xf in my case) later on. rc1's commit has good intentions, but expects cpu_present_map to be limited by maxcpus, which is only the case on i386. cpus_and(possible, possible,present) might be good, but needs an audit of cpu_present_map uses - there may well be assumptions that any cpu present is possible. So stay safe for now and just revert those #ifndef CONFIG_HOTPLUG_CPU optimizations in rc1's commit. Signed-off-by:
