The accidental loss of CONFIG_DIO in commit 0e152d80 ("m68k: reorganize Kconfig options to improve mmu/non-mmu selections") exposed a missing symbol export in m68k allmodconfig. If CONFIG_HP300=y but CONFIG_HPLANCE (which is bool, and depends on CONFIG_DIO) is not set, and CONFIG_MVME147=y and CONFIG_MVME147_NET=m, 7990.c is compiled as a module, giving: ERROR: "ledstate" [drivers/net/ethernet/amd/7990.ko] undefined! Add the missing export, and rename ledstate to hp300_ledstate while we're at it, as it's a too generic name. Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org>

The baboon_disabled hack is broken because it is missing an irq shutdown method. So releasing a Baboon irq kills the other Baboon irqs. But we don't really need this hack because we don't have media bay support and TREX uses a NuBus IRQ. Remove it.

The IOP driver calls into the OSS driver to enable its IRQ. This undesirable coupling between drivers only exists because the OSS driver doesn't correctly handle all of its machspec IRQs. Fix OSS handling of enable/disable for VIA1 IRQs (8 thru 15) which includes MAC_IRQ_ADB. Back when I implemented pmac_zilog support I redefined IRQ_MAC_SCC incorrectly. Change this to a machspec IRQ so that it works on OSS. Clean up the unused OSS audio IRQ and OSS_IRQLEV_* cruft that only confuses things. Fix the OSS description in macints.c and remove an obsolete comment. Don't enable the VIA1 irq before registering the handler.

Enable via_alt_mapping on the Performa 588 and tidy up related documentation. I'm betting that remapped IRQs work just fine on the Performa 580 series since it works on the LC 630 and the logic board part numbers are reputedly the same. And the consensus seems to be that the Mac TV is essentially a Performa 550, not dissimilar to the Performa 520, so set the via_type accordingly.

Revive the old mac_serial_print() routine as mac_early_print(). mac_serial_print() did not function because it did not use the right offsets for its stack arguments. Fix this and make compilation conditional on CONFIG_EARLY_PRINTK instead of the obscure MAC_SERIAL_DEBUG macro. Give mac_early_print() a new string length parameter to fit the early console API. Send output to the framebuffer as well as serial ports. Change the line rate to 38400 baud to match the default for the real (pmac_zilog) serial console.

Since commit a25cac51 ("proc: Consider NO_HZ when printing idle and iowait times") we are reporting idle/io_wait time also while a CPU is tickless. We rely on get_{idle,iowait}_time functions to retrieve proper data. These functions, however, use usecs_to_cputime to translate micro seconds time to cputime64_t. This is just an alias to usecs_to_jiffies which reduces the data type from u64 to unsigned int and also checks whether the given parameter overflows jiffies_to_usecs(MAX_JIFFY_OFFSET) and returns MAX_JIFFY_OFFSET in that case. When we overflow depends on CONFIG_HZ but especially for CONFIG_HZ_300 it is quite low (1431649781) so we are getting MAX_JIFFY_OFFSET for >3000s! until we overflow unsigned int. Just for reference CONFIG_HZ_100 has an overflow window around 20s, CONFIG_HZ_250 ~8s and CONFIG_HZ_1000 ~2s. This results in a bug when people saw [h]top going mad reporting 100% CPU usage even though there was basically no CPU load. The reason was simply that /proc/stat stopped reporting idle/io_wait changes (and reported MAX_JIFFY_OFFSET) and so the only change happening was for user system time. Let's use nsecs_to_jiffies64 instead which doesn't reduce the precision to 32b type and it is much more appropriate for cumulative time values (unlike usecs_to_jiffies which intended for timeout calculations).

Commit f5252e00 ("mm: avoid null pointer access in vm_struct via /proc/vmallocinfo") adds newly allocated vm_structs to the vmlist after it is fully initialised. Unfortunately, it did not check that __vmalloc_area_node() successfully populated the area. In the event of allocation failure, the vmalloc area is freed but the pointer to freed memory is inserted into the vmlist leading to a a crash later in get_vmalloc_info(). This patch adds a check for ____vmalloc_area_node() failure within __vmalloc_node_range. It does not use "goto fail" as in the previous error path as a warning was already displayed by __vmalloc_area_node() before it called vfree in its failure path.

With the 3.2-rc kernel, IOMMU 2M pages in KVM works. But when I tried to use IOMMU 1GB pages in KVM, I encountered an oops and the 1GB page failed to be used. The root cause is that 1GB page allocation calls gup_huge_pud() while 2M page calls gup_huge_pmd. If compound pages are used and the page is a tail page, gup_huge_pmd() increases _mapcount to record tail page are mapped while gup_huge_pud does not do that. So when the mapped page is relesed, it will result in kernel oops because the page is not marked mapped. This patch add tail process for compound page in 1GB huge page which keeps the same process as 2M page. Reproduce like: 1. Add grub boot option: hugepagesz=1G hugepages=8 2. mount -t hugetlbfs -o pagesize=1G hugetlbfs /dev/hugepages 3. qemu-kvm -m 2048 -hda os-kvm.img -cpu kvm64 -smp 4 -mem-path /dev/hugepages -net none -device pci-assign,host=07:00.1 kernel BUG at mm/swap.c:114! invalid opcode: 0000 [#1] SMP Call Trace: put_page+0x15/0x37 kvm_release_pfn_clean+0x31/0x36 kvm_iommu_put_pages+0x94/0xb1 kvm_iommu_unmap_memslots+0x80/0xb6 kvm_assign_device+0xba/0x117 kvm_vm_ioctl_assigned_device+0x301/0xa47 kvm_vm_ioctl+0x36c/0x3a2 do_vfs_ioctl+0x49e/0x4e4 sys_ioctl+0x5a/0x7c system_call_fastpath+0x16/0x1b RIP put_compound_page+0xd4/0x168 Signed-off-by: NYouquan Song <youquan.song@intel.com> Reviewed-by: NAndrea Arcangeli <aarcange@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: <stable@vger.kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

khugepaged can sometimes cause suspend to fail, requiring that the user retry the suspend operation. Use wait_event_freezable_timeout() instead of schedule_timeout_interruptible() to avoid missing freezer wakeups. A try_to_freeze() would have been needed in the khugepaged_alloc_hugepage tight loop too in case of the allocation failing repeatedly, and wait_event_freezable_timeout will provide it too. khugepaged would still freeze just fine by trying again the next minute but it's better if it freezes immediately.
