2009-08-21lib/swiotlb.c: Fix strange panic message selection logic when swiotlb fills upCasey Dahlin1-6/+9
swiotlb_full() in lib/swiotlb.c throws one of two panic messages based on whether the direction of transfer is from the device or to the device. The logic around this is somewhat weird in the case of bidirectional transfers. It appears to want to throw both in succession, but since its a panic only the first makes it. This patch adds a third, separate error for DMA_BIDIRECTIONAL to make things a bit clearer.

2009-08-10sparc: Add CONFIG_DMA_API_DEBUG supportFUJITA Tomonori5-34/+39
All we need to do for CONFIG_DMA_API_DEBUG support is call dma_debug_init() in DMA code common for SPARC32 and SPARC64. Now SPARC32 uses two dma_map_ops structures for pci and sbus so there is not much dma stuff for SPARC32 in kernel/dma.c. kernel/ioport.c also includes dma stuff for SPARC32. So let's put all the dma stuff for SPARC32 in kernel/ioport.c and make kernel/dma.c common for SPARC32 and SPARC64.

2009-08-10sparc: Use asm-generic/pci-dma-compatFUJITA Tomonori9-444/+96
This converts SPARC to use asm-generic/pci-dma-compat instead of the homegrown mechnism. SPARC32 has two dma_map_ops structures for pci and sbus (removing arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor). The global 'dma_ops' is set to sbus_dma_ops and get_dma_ops() returns pci32_dma_ops for pci devices so we can use the appropriate dma mapping operations.

sbus_unmap_page This is a preparation for using asm-generic/pci-dma-compat.h; SPARC32 has two dma_map_ops structures for pci and sbus (removing arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor).

Now sparc uses include/asm-generic/dma-mapping-common.h. pci_sun4v.c doesn't need to have no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu (dma-mapping-common.h does nothing if sync_{single|sg}_for_cpu hook is not defined).

2009-08-10dma-ops: Remove flush_write_buffers() in dma-mapping-common.hArnd Bergmann2-11/+22
This moves flush_write_buffers() in asm-generic/dma-mapping-common.h to arch/x86/kernel/pci-nommu.c. The purpose of this patch is that, we can avoid defining NULL flush_write_buffers() on IA64 and SPARC. dma-mapping-common.h is used by X86 and IA64 (and SPARC soon) but only X86 with CONFIG_X86_OOSTORE or CONFIG_X86_PPRO_FENCE actually uses flush_write_buffers(). CONFIG_X86_OOSTORE or CONFIG_X86_PPRO_FENCE is usable with only kernel/pci-nommu.c (that is, not usable with other X86 IOMMU implementations such as SWIOTLB, VT-d, etc) so we can safely move flush_write_buffers() in asm-generic/dma-mapping-common.h to arch/x86/kernel/pci-nommu.c.

This fixes - locking bug that was hidden by ecc2e05e739c30870c8e4f252b63a0c4041f2724 - Regression #13821 - Spurious warning when closing and blocking for data write out With these changes my PL2303 always ends up as ttyUSB0 when it should and the module refcounts stay correct. I'll do a more wholesale split & tidy of _open in the next release or two as we get a standard tty_port_open and port->ops->init port->ops->shutdown call backs. Copy sent to Alan Stern and Carlos Mafra just to confirm it fixes all the reports but it passes local testing with the same hardware as Alan Stern.

2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt34-82/+107
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

2009-07-27cnic: Fix ISCSI_KEVENT_IF_DOWN message handling.Michael Chan1-2/+21
When a net device goes down or when the bnx2i driver is unloaded, the code was not generating the ISCSI_KEVENT_IF_DOWN message properly and this could cause the userspace driver to crash. This is fixed by sending the message properly in the shutdown path. cnic_uio_stop() is also added to send the message when bnx2i is unregistering.

2009-07-27microblaze: Makefile cleanupSam Ravnborg2-18/+19
Reviewed the Makefile on request by Michal and this is the resulting changes. o Use ':=' for assignmnet so we do not re-evaluate for each use o Use $(shell echo xxx) to remove "" o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS The settings are equally relevant for modules and the linked kernel o Dropped LDFLAGS_BLOB - it is no longer used o Refactored assignmnets to libs-y and core-y o Use MMU for the MMU specific extension. "MMUEXT" was hurting my eyes and I did not wanted it spread to m68k Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-07-27microblaze: Get module loading workingJohn Williams1-5/+10
New reloc type R_MICROBLAZE_32_PCREL_LO requires a null handler (no work to do). Remove legacy hack for broken linker pre gcc-4.1.1, that required us to extract an offset from the code, add it to the addend, then rewrite the instruction. Fixup the invalid reloc type error output.
