* x86: UV BAU and nodes with no memoryCliff Wickman2009-04-03
| | | | | | | | | | | | | | | This patch fixes BAU initialization for systems containing nodes with no memory and for systems with non-consecutive node numbers. Fixes and clarifies situations where pnode should be used instead of node id. Tested on the UV hardware simulator.

| * x86/dma: unify definition of pci_unmap_addr* and pci_unmap_len macrosJoerg Roedel2009-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: unification of pci-dma macros and pci_32.h removal This patch unifies the definition of the pci_unmap_addr*, pci_unmap_len* and DECLARE_PCI_UNMAP* macros. This makes sense because the pci_unmap functions are no longer no-ops anymore when the kernel runs with CONFIG_DMA_API_DEBUG. Without an iommu or DMA_API_DEBUG it is a no-op on 32 bit because the dma mapping path returns a physical address and therefore the dma-api implementation has no internal state which needs to be destroyed with an unmap call. This unification also simplifies the port of x86_64 iommu drivers to 32 bit x86 and let us get rid of pci_32.h.

| | * Remove two unneeded exports and make two symbols static in fs/mpage.cDmitri Vorobiev2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 29a814d2ee0e43c2980f33f91c1311ec06c0aa35 (vfs: add hooks for ext4's delayed allocation support) exported the following functions mpage_bio_submit() __mpage_writepage() for the benefit of ext4's delayed allocation support. Since commit a1d6cc563bfdf1bf2829d3e6ce4d8b774251796b (ext4: Rework the ext4_da_writepages() function), these functions are not used by the ext4 driver anymore. However, the now unnecessary exports still remain, and this patch removes those. Moreover, these two functions can become static again. The issue was spotted by namespacecheck.

Changes: - fix a copy&paste error in i8xx fence reg setup. It resulted in an at most a 512KB offset of the fence reg window, so was only visible sometimes. - add tests for stride and object size constrains (also for i915 and 1965 class hw). Userspace seems to have an of-by-one bug there, which changes the fence size by at most 512KB due to an overflow. - because i8xx hw is quite old (and therefore not as well-tested) I left 2 debug WARN_ONs in the i8xx fence reg setup code to hopefully catch any further overflows in the bit-fields. Lastly there's one small change to make the alignment checks more consistent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed the order in which things are freed. This fixes an oops when unplugging the device while network traffic is ongoing. Signed-off-by: Jan Dumon <j.dumon@option.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This is because fsl_pq_mdio driver wrongly masks all non-TBI PHYs for !fsl,gianfar-mdio buses, while it should do that only for fsl,gianfar-tbi buses.
