2007-08-31Add MAINTAINERS entry for IOC3 serial driverRalf Baechle
The IOC3 is a multifunction device but not in sense of the PCI specification. Currently its ethernet and serial functionality are supported by two separate drivers authored and maintained by different people, so MAINTAINERS should reflect that.

2007-08-31SPI driver hotplug/coldplug fixesDavid Brownell
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.

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.

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.

2007-08-30[SPARC64]: Fix several bugs in MSI handling.David S. Miller
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: David S. Miller <davem@davemloft.net>

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.

2007-08-30[BRIDGE]: Fix OOPS when bridging device without ethtool.Stephen Hemminger
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.

2007-08-30fix maxcpus=1 oops in show_stat()Hugh Dickins
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 61ec7567db103d537329b0db9a887db570431ff4 (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 8b3b295502444340dd0701855ac422fbf32e161d (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.
