Problem: A recovery thread must not be active when device is removed. In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.

This patch fixes two problems during driver unload. The pci_disable_device() call is before firmware reload, causing reads and writes across PCI bus after disabling device. Second problem is the register window was wrong during firmware reload Signed-off by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

The IOC3 driver's UART detection bits used to rely on the the firmware setting the UART pre-divider in a way that's apropriate for the 8250 driver which doesn't currently program this register. This happens to work for the console but not rarely for additional ports. While at it, also program the UART to RS-232 PIO mode; it the UART might have been in mac-serial and/or DMA mode though that hasn't actually been observed in practice.

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.

This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

When a process writes into the inbound spu mailbox (wbox) while the context is saved, we accidentally break the contents of the mb_stat_R register by clearing other entries of the mailbox status register. This can cause the user side to hang. This change fixes the problem by only altering the appropriate bits of the mailbox status register during a backing-store write.

This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

When we flush register state for FP, Altivec, or SPE in flush_*_to_thread we need to respect the task_struct that the caller has passed to us. Most cases we are called with current, however sometimes (ptrace) we may be passed a different task_struct. This showed up when using gdbserver debugging a simple program that used floating point. When gdb tried to show the FP regs they all showed up as 0, because the child's FP registers were never properly flushed to memory. Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

As pointed out by Jrgen, we are overflowing the number of GPIOs in pxa_init_irq_gpio(). I'm seeing the same problem on my HTC Universal PXA270 based PDA.

Sigh. Again an ACPI assault on the Thinkpad's Fn+F4 to suspend to RAM. The default and text for CONFIG_THINKPAD_ACPI_INPUT_ENABLED were fixed in -rc3, but now commit 14e04fb3 ("ACPI: Schedule /proc/acpi/event for removal") introduces the ACPI_PROC_EVENT config entry, and defaults it to 'n' to disable it again.

Commit 61ec7567 ('ACPI: boot correctly with "nosmp" or "maxcpus=0"') broke 'maxcpus=' handling on x86[-64]. maxcpus=N is now having no effect on x86_64, and freezing bootup on i386 (because of inconsistency with the separate maxcpus parsing down in arch/i386, I guess). That's because early_param parsing is a little different from __setup parsing, and needs the "=" omitted: then it seems to work as the original commit intended (no mention of IO-APIC in /proc/interrupts when maxcpus=0).
