Some fixes and cleanups from the linux-mac68k repo. Fix mac_esp by clearing the VIA2 SCSI IRQ flag before the SCSI IRQ handler is invoked. Also fix a race condition caused by unmasking a nubus slot IRQ then setting the relevant nubus_active bit. Signed-off-by:

Dump the extra mapping in the amikbd interrupt handler, so old Amiga keymaps work again. Amigas need a special keymap anyway, standard keymaps are not usable and recreating all keymaps is simply not worth the trouble. Signed-off-by:

ide_setup_ports does not completely initialize the hw_regs_t structure which can cause random failures, as the structure is often on the stack. None of the callers expect a partially initialized structure, i.e. none of them do any setup of their own before calling ide_setup_ports(). Signed-off-by:

Make swsusp allocate only as much memory as needed to store the image data and metadata during resume. Without this patch swsusp additionally allocates many page frames that will conflict with the "original" locations of the image data and are considered as "unsafe", treating them as "eaten" pages (ie. allocated but unusable). The patch makes swsusp allocate as many pages as it'll need to store the data read from the image in one shot, creating a list of allocated "safe" pages, and use the observation that all pages allocated by it are marked with the PG_nosave and PG_nosave_free flags set. Namely, when it's about to load an image page, swsusp can check whether the page frame corresponding to the "original" location of this page has been allocated (ie. if the page frame has the PG_nosave and PG_nosave_free flags set) and if so, it can load the page directly into this page frame. Otherwise it uses an allocated "safe" page from the list to store the data that will be copied to their "original" location later on. This allows us to save many page copyings and page allocations during resume and in the future it may allow us to load images greater than 50% of the normal zone. Signed-off-by:

swsusp allocates memory from the normal zone, so it cannot use lowmem reserve pages from the lower zones. Therefore it should not count these pages as available to it. Signed-off-by:

1. Add architecture specific pages save/restore support. Next two patches will use this to save/restore 'ACPI NVS' pages. 2. Allow reserved pages 'nosave'. This could avoid save/restore BIOS reserved pages. Signed-off-by:

Sometimes thread_info and task_struct get out-of-sync with each other. Printing task.thread_info in show_registers() can help spot this. And when task_struct is corrupt then task.comm can contain garbage, so only print as many characters as it can hold. Signed-off-by:

The i386 page fault handler does not allow enough slack when checking for userspace access below the current stack pointer. This prevents use of the enter instruction by user code.

On i386, kernel irq balance doesn't work. 1) In function do_irq_balance, after kernel finds the min_loaded cpu but before calling set_pending_irq to really pin the selected_irq to the target cpu, kernel does a cpus_and with irq_affinity[selected_irq]. Later on, when the irq is acked, kernel would calls move_native_irq=>desc->handler->set_affinity to change the irq affinity. However, every function pointed by hw_interrupt_type->set_affinity(unsigned int irq, cpumask_t cpumask) always changes irq_affinity[irq] to cpumask. Next time when recalling do_irq_balance, it has to do cpu_ands again with irq_affinity[selected_irq], but irq_affinity[selected_irq] already becomes one cpu selected by the first irq balance. 2) Function balance_irq in file arch/i386/kernel/io_apic.c has the same issue.

When multiple updates matching a given CPU are found in the update file, the action taken by the microcode update driver was inappropriate: - when lower revision microcode was found before matching or higher revision one, the driver would needlessly complain that it would not downgrade the CPU - when microcode matching the currently installed revision was found before newer revision code, no update would actually take place To change this behavior, the driver now concludes about possibly updates and issues messages only when the entire input was parsed. Additionally, this adds back (in different places, and conditionalized upon a new module option) some messages removed by a previous patch. Signed-off-by:
