* powerpc: Add write barrier before enabling DTL flagsJeremy Kerr2009-03-271-0/+4
| | | | | | | | | | | 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. This change adds a smp_wmb() before doing the actual enable. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc/mm: Introduce early_init_mmu() on 64-bitBenjamin Herrenschmidt2009-03-244-34/+43
| | | | | | | | 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 Herrenschmidt2009-03-244-337/+233Star
| | | | | | | | | | | | | | | | | 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 Herrenschmidt2009-03-2412-76/+89
| | | | | | | | | | | | | | | | | 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/mm: e300c2/c3/c4 TLB errata workaroundKumar Gala2009-03-244-7/+45
| | | | | | | | | | | | | Complete workaround for DTLB errata in e300c2/c3/c4 processors. Due to the bug, the hardware-implemented LRU algorythm always goes to way 1 of the TLB. This fix implements the proposed software workaround in form of a LRW table for chosing the TLB-way.

| | | | | | | | | | 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 Gala2009-03-242-13/+36
| | | | | | | | | | | | | | | | 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.

While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections.

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.

This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the regressions cause by commit 1326c3d5a4b792a2b15877feb7fb691f8945d203 (v2.6.28-rc6-461-g23a12b1) broke the display of local and remote addresses of an SIT tunnel in iproute2. nt->parms is used by ipip6_tunnel_init() and therefore need to be initialized first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The NAPI poll parameter netdev_budget is not documented in kernel-docs. Since it may have a substantial effect on at least some network loads, it should be. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| | * tulip: fix crash on iface up with shirq debugKyle McMartin2009-03-191-16/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tulip is currently doing request_irq before it has done its initialization. This is usually not a problem because it hasn't enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler when registering the interrupt as a sanity check. This can result in a NULL ptr dereference, so call tulip_init_ring before request_irq, and add a free_ring function to do the freeing now shared with tulip_close. Tested with a shell loop running ifup, ifdown in a loop a few hundred times with DEBUG_SHIRQ on. Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
