Fix compilation breakage of all m68knommu targets: CC arch/m68knommu/kernel/asm-offsets.s In file included from include/linux/sched.h:77, from arch/m68knommu/kernel/asm-offsets.c:12: include/linux/percpu.h: In function 'per_cpu_ptr_to_phys': include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy This is broken in linux-2.6.33-rc3. Change the definitions of __pa() and __va() to not use virt_to_phys() and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case. A side effect if this is that the m68knommu can now use asm/virtconvert.h for the definition of virt_to_phys() and phys_to_virt(). Also cleaned up the definition of page_to_phys() when moving into virtconvert.h. Signed-off-by: NGreg Ungerer <gerg@uclinux.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Revert commit 2fbd07a5, as this commit breaks an IBM platform with quad-core Xeon cpu's. According to Suresh, this might be an IBM platform issue, as on other Intel platforms with <= 8 logical cpu's, logical flat mode works fine irespective of physical apic id values (inline with the xapic architecture). Revert this for now because of the IBM platform breakage. Another version will be re-submitted after the complete analysis.

The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable pointers in order to trap erronous use of freed list_heads. Unfortunately userspace can arrange for those pointers to actually be dereferencable, potentially turning an oops to an expolit. To avoid this allow architectures (currently x86_64 only) to override the default values for these pointers with truly-undereferencable values. This is easy on x86_64 as the virtual address space is large and contains areas that cannot be mapped. Other 64-bit architectures will likely find similar unmapped ranges.

Access to the ASB2305's PCnet32 NIC doesn't work correctly because when the NIC attempts to update the ring buffer flags by DMA, the change to RAM crops up about 17uS after the interrupt line is asserted. This is almost certainly due to a bug in the PCI bridge FPGA on that board. We can get around this by making dma_alloc_coherent() put the ring buffer in the SRAM attached to the PCI bridge rather than in the SDRAM.

Insert PCI root bus resources for the MN10300-based ASB2305 development kit motherboard. This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window. We also add a reservation for the PCI SRAM region.

gcc 4.2.1 for MN10300 is more agressive than the older gcc in reordering/moving other insns between an insn that sets flags and an insn that uses those flags.

This fixes a signal stack handling problem in the MN10300 arch. When new threads are cloned with CLONE_VM, they don't inherit the alternate signal stack. They do share the signal flags, though. When deciding whether to use an alternate stack, the arch code needs to check to make sure the task struct contains a valid alternate stack. This patch fixes the MN10300 arch by using the sas_ss_flags() test provided by sched.h rather than the on_sig_stack() test which is insufficient by itself.
