This patch adds DT board setup for the LaCie NAS Network Space Mini v2 (aka SafeBox). The hardware characteristics are very close to those of the Network Space Lite v2. The main difference are: - A GPIO fan which is only available on the NS2 Mini. - A single USB host port is wired on the NS2 Mini. The NS2 Lite provides an additional dual-mode USB port (host/device).

2012-11-17revert "mm: fix-up zone present pages"Andrew Morton1-1/+0
Revert commit 7f1290f2f2a4 ("mm: fix-up zone present pages") That patch tried to fix a issue when calculating zone->present_pages, but it caused a regression on 32bit systems with HIGHMEM. With that change, reset_zone_present_pages() resets all zone->present_pages to zero, and fixup_zone_present_pages() is called to recalculate zone->present_pages when the boot allocator frees core memory pages into buddy allocator. Because highmem pages are not freed by bootmem allocator, all highmem zones' present_pages becomes zero. Various options for improving the situation are being discussed but for now, let's return to the 3.6 code.

So it's really just 3 fixes: - Get is_compat_task() to do the right thing while simplifying it. The unnecessary complexity hid a rarely striking bug which could be triggered by ext3/ext4 under certain circumstances. - Resolve a preemption issue in the irqflags.h functions for kernels built to support pre-MIPS32 / pre-MIPS64 Release 2 processors. - Fix the interrupt number of the MIPS Malta's CBUS UART." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Malta: Fix interupt number of CBUS UART. MIPS: Make irqflags.h functions preempt-safe for non-mipsr2 cpus MIPS: Remove irqflags.h dependency from bitops.h MIPS: bitops.h: Change use of 'unsigned short' to 'int' MIPS: compat: Delete now unused TIF_32BIT. MIPS: compat: Implement is_compat_task() by testing for 32-bit address space. MIPS: compat: Fix use of TIF_32BIT_ADDR vs _TIF_32BIT_ADDR
2012-11-13MIPS: Malta: Fix interupt number of CBUS UART.Ralf Baechle1-1/+2
The CBUS UART's interrupt number was wrong conflicting with the interrupt being tied to the Intel PIIX4. Since the PIIX4's interrupt is registered before the CBUS UART which is not being used on most systems this would not be noticed. Attempts to open the ttyS2 CBUS UART would result in: genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade) serial_link_irq_chain: request failed: -16 for irq: 18 Qemu was written to match the kernel so will need to be fixed also.

2012-11-13s390/mm: have 16 byte aligned struct pagesHeiko Carstens1-0/+1
Select HAVE_ALIGNED_STRUCT_PAGE on s390, so that the slub allocator can make use of compare and swap double for lockless updates. This increases the size of struct page to 64 bytes (instead of 56 bytes), however the performance gain justifies the increased size: - now excactly four struct pages fit into a single cache line; the case that accessing a struct page causes two cache line loads does not exist anymore. - calculating the offset of a struct page within the memmap array is only a simple shift instead of a more expensive multiplication. A "hackbench 200 process 200" run on a 32 cpu system did show an 8% runtime improvement.

2012-11-13s390/gup: fix access_ok() usage in __get_user_pages_fast()Heiko Carstens1-2/+1
access_ok() returns always "true" on s390. Therefore all access_ok() invocations are rather pointless. However when walking page tables we need to make sure that everything is within bounds of the ASCE limit of the task's address space. So remove the access_ok() call and add the same check we have in get_user_pages_fast().

2012-11-13s390/gup: add missing TASK_SIZE check to get_user_pages_fast()Heiko Carstens1-1/+1
When walking page tables we need to make sure that everything is within bounds of the ASCE limit of the task's address space. Otherwise we might calculate e.g. a pud pointer which is not within a pud and dereference it. So check against TASK_SIZE (which is the ASCE limit) before walking page tables.

On hosts without the XSAVE support unprivileged local user can trigger oops similar to the one below by setting X86_CR4_OSXSAVE bit in guest cr4 register using KVM_SET_SREGS ioctl and later issuing KVM_RUN ioctl. invalid opcode: 0000 [#2] SMP Modules linked in: tun ip6table_filter ip6_tables ebtable_nat ebtables ...

So guest's X86_FEATURE_XSAVE should be masked out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with X86_FEATURE_XSAVE even on hosts that do not support it, might be susceptible to this attack from inside the guest as well. Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support. Signed-off-by: Petr Matousek <pmatouse@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
