| * powerpc/85xx: Add support for the "socrates" board (MPC8544).Wolfgang Grandegger2009-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Supported are Ethernet, serial console, I2C, I2C-based RTC and temperature sensors, NOR and NAND flash, PCI, USB, CAN and Lime display controller. The multiplexing of FPGA interrupts onto PowerPC interrupt lines is supported through our own fpga_pic interrupt controller driver. For example the SJA1000 controller is level low sensitive connected to fpga_pic line 2 and is routed to the second (of three) irq lines to the CPU: can@3,100 { compatible = "philips,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 2>; interrupts = <2 8 1>; // number, type, routing interrupt-parent = <&fpga_pic>; }; Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Ilya Yanok <yanok@emcraft.com> Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Dmitry Rakhchev <rda@emcraft.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * powerpc/83xx: Add power management support for MPC837x boardsAnton Vorontsov2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds pmc nodes to the device tree files so that the boards will able to use standby capability of MPC837x processors. The MPC837x PMC controllers are compatible with MPC8349 ones (i.e. no deep sleep). sleep = <> properties are used to specify SCCR masks as described in "Specifying Device Power Management Information (sleep property)" chapter in Documentation/powerpc/booting-without-of.txt. Since I2C1 and eSDHC controllers share the same clock source, they are now placed under sleep-nexus nodes. A processor is able to wakeup the boards on LAN events (Wake-On-Lan), console events (with no_console_suspend kernel command line), GPIO events and external IRQs (IRQ1 and IRQ2). The processor can also wakeup the boards by the fourth general purpose timer in GTM1 block, but the GTM wakeup support isn't yet implemented (it's tested to work, but it's unclear how can we use the quite short GTM timers, and how do we want to expose the GTM to userspace).

* | powerpc: Sanitize stack pointer in signal handling codeJosh Boyer2009-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On powerpc64 machines running 32-bit userspace, we can get garbage bits in the stack pointer passed into the kernel. Most places handle this correctly, but the signal handling code uses the passed value directly for allocating signal stack frames. This fixes the issue by introducing a get_clean_sp function that returns a sanitized stack pointer. For 32-bit tasks on a 64-bit kernel, the stack pointer is masked correctly. In all other cases, the stack pointer is simply returned. Additionally, we pass an 'is_32' parameter to get_sigframe now in order to get the properly sanitized stack. The callers are know to be 32 or 64-bit statically. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* | powerpc: Add write barrier before enabling DTL flagsJeremy Kerr2009-03-27
|/ | | | | | | | | | | Currently, we don't enforce any ordering for updates to the lppaca when enabling dtl logging, so we may end up enabling logging before the index fields have been established.

* powerpc/mm: Introduce early_init_mmu() on 64-bitBenjamin Herrenschmidt2009-03-23
| | | | | | | | This moves some MMU related init code out of setup_64.c into hash_utils_64.c and calls it early_init_mmu() and early_init_mmu_secondary(). This will make it easier to plug in a new MMU type. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* powerpc/mm: Merge various PTE bits and accessors definitionsBenjamin Herrenschmidt2009-03-23
| | | | | | | | | | | | | | | | | Now that they are almost identical, we can merge some of the definitions related to the PTE format into common files. This creates a new pte-common.h which is included by both 32 and 64-bit right after the CPU specific pte-*.h file, and which defines some bits to "default" values if they haven't been defined already, and then provides a generic definition of most of the bit combinations based on these and exposed to the rest of the kernel. I also moved to the common pgtable.h most of the "small" accessors to the PTE bits and modification helpers (pte_mk*). The actual accessors remain in their separate files.

* powerpc/mm: Tweak PTE bit combination definitionsBenjamin Herrenschmidt2009-03-23
| | | | | | | | | | | | | | | | | This patch tweaks the way some PTE bit combinations are defined, in such a way that the 32 and 64-bit variant become almost identical and that will make it easier to bring in a new common pte-* file for the new variant of the Book3-E support. The combination of bits defining access to kernel pages are now clearly separated from the combination used by userspace and the core VM. The resulting generated code should remain identical unless I made a mistake. Note: While at it, I removed a non-sensical statement related to CONFIG_KGDB in ppc_mmu_32.c which could cause kernel mappings to be user accessible when that option is enabled. Probably something that bitrot. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* powerpc: expect all devices calling dma ops to have archdata setKumar Gala2009-03-23
| | | | | | | | | | Now that we set archdata for of_platform and platform devices via platform_notify() we no longer need to special case having a NULL device pointer or NULL archdata.

* powerpc: setup default archdata for {of_}platform via bus_register_notifierKumar Gala2009-03-23
| | | | | | | | | | | | | | | | Since a number of powerpc chips are SoCs we end up having dma-able devices that are registered as platform or of_platform devices. We need to hook the archdata to setup proper dma_ops for these devices. Rather than having to add a bus_notify to each platform we add a default one at the highest priority (called first) to set the default dma_ops for of_platform and platform devices to dma_direct_ops. This allows platform code to override the ops by providing their own notifier call back. In the future to enable >4G DMA support on ppc32 we can hook swiotlb ops.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

| | | * nl80211: Check that function pointer != NULL before using itJouni Malinen2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS handlers did not verify whether a function pointer is NULL (not supported by the driver) before trying to call the function. The former nl80211 command is available for unprivileged users, too, so this can potentially allow normal users to kill networking (or worse..) if mac80211 is built without CONFIG_MAC80211_MESH=y.
