* [POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnableAndre Detsch2007-08-301-5/+1
| | | | | | | | | | | | | | | | This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

* [POWERPC] spufs: Fix update of mailbox status register during backed wbox writeArnd Bergmann2007-08-301-1/+2
| | | | | | | | | | | | | | When a process writes into the inbound spu mailbox (wbox) while the context is saved, we accidentally break the contents of the mb_stat_R register by clearing other entries of the mailbox status register. This can cause the user side to hang. This change fixes the problem by only altering the appropriate bits of the mailbox status register during a backing-store write.

* [POWERPC] spu_manage: fix spu_unit_number for celleb device treeChristian Krafft2007-08-301-0/+8
| | | | | | | | | | | | | | | | | | | | This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

* [POWERPC] Flush registers to proper task contextKumar Gala2007-08-281-3/+3
| | | | | | | | | | | | | | When we flush register state for FP, Altivec, or SPE in flush_*_to_thread we need to respect the task_struct that the caller has passed to us. Most cases we are called with current, however sometimes (ptrace) we may be passed a different task_struct. This showed up when using gdbserver debugging a simple program that used floating point. When gdb tried to show the FP regs they all showed up as 0, because the child's FP registers were never properly flushed to memory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Fix SLB initialization at boot timePaul Mackerras2007-08-251-8/+28
| | | | | | | | | | | | | | | This partially reverts edd0622bd2e8f755c960827e15aa6908c3c5aa94. It turns out that the part of that commit that aimed to ensure that we created an SLB entry for the kernel stack on secondary CPUs when starting the CPU didn't achieve its aim, and in fact caused a regression, because get_paca()->kstack is not initialized at the point where slb_initialize is called. This therefore just reverts that part of that commit, while keeping the change to slb_flush_and_rebolt, which is correct and necessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

Changes in the axonram module are necessary because in the old version, if it is not allowed to fetch the second interrupt number from device-tree, it interpretes this as an error case and exits.

* [POWERPC] cell: Support pinhole-reset on IBM cell bladesArnd Bergmann2007-08-252-2/+32
| | | | | | | | | | | | | | | | | | | | | The Cell Broadband Engine has a method of injecting a system-reset-exception from an external source into the operating system, which should trigger the regular behaviour of entering xmon or kdump. Unfortunately, the exception handler cannot distinguish it from other interrupt causes by the SRR1 register, which gets used for this on Power 6 and others. IBM Blade servers that want to support triggering the system reset exception using a pinhole button in the front panel therefore use an extra register to determine the reset cause.

* [POWERPC] spu_manage: Use newer physical-id attributeChristian Krafft2007-08-252-6/+2
| | | | | | | | | | | | | | | Legacy device tree used the reg property for the physical id of an spe. On newer device tree layouts the reg property contains the "correct" value in the reg attribute. So there has been intoduced the "physical-id" on newer devicetree layouts. The id is stored by spu_manage into the spu struct as spe_id. cbe_thermal has been changed to use the spu->spe_id. There's no need for the thermal code to check devicetree attributes for itself.

Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

* | [POWERPC] Fix small race in 44x tlbie functionDavid Gibson2007-08-151-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | My "slices" address space management code that was added in the 2.6.22 implementation of get_unmapped_area() doesn't properly check that the size is a multiple of the requested page size. This allows userland to create VMAs that aren't a multiple of the huge page size with hugetlbfs (since hugetlbfs entirely relies on get_unmapped_area() to do that checking) which leads to a kernel BUG() when such areas are torn down.

| | | | | | | | | | | | | | | 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.

* | Remove fs.h from mm.hAlexey Dobriyan2007-07-293-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).
