We need to have xLparMap in head_64.S so that it is at a fixed address (because the linker will not resolve (address & 0xffffffff) for us). But the assembler miscalculates the KERNEL_VSID() expressions. So put the confusing expressions into asm-offsets.c.

The built-in IDE controller is configured in legacy mode, but the PCI registers advertise native mode. Force the PCI class into legacy mode. This allows pata_via to access two drives. The Pegasos specific irq enforcement in the via82cxxx driver must stay because there is apparently no generic way to setup irq per channel. Tested on Pegasos2 with firmware version 20040810, and two IDE disks. Signed-off-by: NOlaf Hering <olaf@aepfle.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This adds code to handle alignment traps generated by the following new floating-point load/store instructions, by emulating the instruction in the kernel (as is done for other instructions that generate alignment traps): lfiwax load floating-point as integer word algebraic indexed stfiwx store floating-point as integer word indexed lfdp load floating-point double pair lfdpx load floating-point double pair indexed stfdp store floating-point double pair stfdpx store floating-point double pair indexed All these except stfiwx are new in POWER6. lfdp/lfdpx/stfdp/stfdpx load and store 16 bytes of memory into an even/odd FP register pair. In little-endian mode each 8-byte value is byte-reversed separately (i.e. not as a 16-byte unit). lfiwax/stfiwx load or store the lower 4 bytes of a floating-point register from/to memory; lfiwax sets the upper 4 bytes of the FP register to the sign extension of the value loaded.

ppc64 does the unusual thing of using #include on a compiler-generated assembly file (lparmap.s) from an assembly source file (head_64.S).

The 440 family of processors don't have a tlbie instruction. So, we implement TLB invalidates by explicitly searching the TLB with tlbsx., then clobbering the relevant entry, if any. Unfortunately the PID for the search needs to be stored in the MMUCR register, which is also used by the TLB miss handler. Interrupts were enabled in _tlbie(), so an interrupt between loading the MMUCR and the tlbsx could cause incorrect search results, and thus a failure to invalide TLB entries which needed to be invalidated. This fixes the problem in both arch/ppc and arch/powerpc by inhibiting interrupts (even critical and debug interrupts) across the relevant instructions.

powerpc has a couple of bugs in the usage of dma_masks that tend to break when drivers explicitly try to set a 32-bit mask for example. First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument. This fixes these problems. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NPaul Mackerras <paulus@samba.org>

In smp_call_function_map(), num_cpus is set to the number of online CPUs minus one. However, if the CPU mask does not include all CPUs (except the one we're running on), the routine will hang in the first while() loop until the 8 second timeout occurs. The num_cpus should be set to the number of CPUs specified in the mask passed into the routine, after we've made any modifications to the mask. With this change, we can also get rid of the call to cpus_empty() and avoid adding another pass through the bitmask.

This patch uses the newly added functions for testing if an address is an ISA or PCI IO port to properly unmap things in pci_iounmap that aren't such ports.

As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse controller on the PegasosPPC. This is because of a feature/bug in the OF device tree: the "device_type" attribute is an empty string instead of "8042" as the kernel expects. This adds a secondary detection which looks for a device whose *name* is "8042" if there is no device whose *type* is "8042".

This reverts commit fd6e9d39. Having #size-cells == 0 in a node indicates that things under the node aren't directly accessible, and therefore we shouldn't try to translate addresses for devices under the node into CPU physical addresses. Some drivers, such as the nvram driver for powermacs, rely on of_address_to_resource failing if they are called for a node representing a device whose resources aren't directly accessible by the CPU. These drivers were broken by commit fd6e9d39, resulting in the "Lombard" powerbook hanging early in the boot process. Signed-off-by: NPaul Mackerras <paulus@samba.org>

In addition, a 'cell' subdirectory was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code. Exports spu_set_profile_private_kref and spu_get_profile_private_kref which are used by OProfile to store private profile information in spufs data structures. Also incorporated several fixes from other patches (rrn). Check pointer returned from kzalloc. Eliminated unnecessary cast.
