Separate the SPEAr host controller driver from ehci-hcd host code so that it can be built as a separate driver module. This work is part of enabling multi-platform kernels on ARM; however, note that other changes are still needed before SPEAr can be booted with a multi-platform kernel, but they are queued in the arm-soc tree for 3.10. With the infrastructure added by Alan Stern in patch 3e023203 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the SPEAr bus glue. In V4 (arnd): - renamed all 'struct spear_ehci' pointers from 'ehci' to the less ambiguous 'sehci'. - folded trivial spear_start_ehci/spear_stop_ehci functions into callers. - brought back initialization of ehci->caps. In V3: - Detailed commit message added here about why this patch is required. - Eliminated ehci_spear_setup routine because hcd registers can be directly set in the spear_ehci_hcd_drv_probe function. - spear_overrides struct initialized. - Converted to using .extra_priv_size for allocating spear_ehci, and updated all users of that structure. - to_spear_ehci() macro modified for spear_ehci. In V2: - Replaced spear as SPEAr everywhere, leaving functions/variables/config options.

Separate the Orion host controller driver from ehci-hcd host code into its own driver module because of following reason. With the multiplatform changes in arm-soc tree, it becomes possible to enable the mvebu platform (which uses ehci-orion) at the same time as other platforms that require a conflicting EHCI bus glue. At the moment, this results in a warning like drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable] and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e023203 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the orion bus glue. An earlier version of this patch was included in 3.9 but caused a regression there, which has subsequently been fixed. While we are here, use the opportunity to disabiguate the two Marvell EHCI controller implementations in Kconfig. In V4 (arnd): - Improve Kconfig text In V3: - More detail provided in commit message regarding this patch. - Replaced hcd_name string "ehci-orion" into "orion-ehci". - MODULE_LICENSE is GPL v2. - In ehci_init_driver calling second argument passed as NULL instead of ehci_orion_overrides because ehci_orion_overrides is removed. In V2: - Tegra patch related changes removed from this patch.

Felipe writes: usb: patches for v3.10 merge window Here is the big Gadget & PHY pull request. Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.

eboot.o and efi_stub_$(BITS).o didn't get added to "targets", and hence their .cmd files don't get included by the build machinery, leading to the files always getting rebuilt. Rather than adding the two files individually, take the opportunity and add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment at the top of the file to be shrunk quite a bit. At the same time, remove a pointless flags override line - the variable assigned to was misspelled anyway, and the options added are meaningless for assembly sources.

The udc uses an shared dma memory space between hard and software. This memory layout is described in ci13xxx_qh and ci13xxx_td which are marked with the attribute ((packed)). The compiler currently does not know about the alignment of the memory layout, and will create strb and ldrb operations. The Datasheet of the synopsys core describes, that some operations on the mapped memory need to be atomic double word operations. I.e. the next pointer addressing in the qhead, as otherwise the hardware will read wrong data and totally stuck. This is also possible while working with the current active td queue, and preparing the td->ptr.next in software while the hardware is still working with the current active td which is supposed to be changed: writeb(0xde, &td->ptr.next + 0x0); /* strb */ writeb(0xad, &td->ptr.next + 0x1); /* strb */ <----- hardware reads value of td->ptr.next and get stuck! writeb(0xbe, &td->ptr.next + 0x2); /* strb */ writeb(0xef, &td->ptr.next + 0x3); /* strb */ This appeares on armv5 machines where the hardware does not support unaligned 32bit operations. This patch adds the attribute ((aligned(4))) to the structures to tell the compiler to use 32bit operations. It also adds an wmb() for the prepared TD data before it gets enqueued into the qhead.

Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code to reset nf_trace in nf_reset(). This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch changes GFS2's discard issuing code so that it calls function sb_issue_discard rather than blkdev_issue_discard. The code was calling blkdev_issue_discard and specifying the correct sector offset and sector size, but blkdev_issue_discard expects these values to be in terms of 512 byte sectors, even if the native sector size for the device is different. Calling sb_issue_discard with the BLOCK size instead ensures the correct block-to-512b-sector translation. I verified that "minlen" is specified in blocks, so comparing it to a number of blocks is correct.

A recent patch to fix the dm cache target's writethrough mode extended the bio's front_pad to include a 1056-byte struct dm_bio_details. Writeback mode doesn't need this, so this patch reduces the per_bio_data_size to 16 bytes in this case instead of 1096. The dm_bio_details structure was added in "dm cache: fix writes to cache device in writethrough mode" which fixed commit e2e74d61 ("dm cache: fix race in writethrough implementation"). In writeback mode we avoid allocating the writethrough-specific members of the per_bio_data structure (the dm_bio_details structure included).

Darrick J. Wong authored
The dm-cache writethrough strategy introduced by commit e2e74d61 ("dm cache: fix race in writethrough implementation") issues a bio to the origin device, remaps and then issues the bio to the cache device. This more conservative in-series approach was selected to favor correctness over performance (of the previous parallel writethrough). However, this in-series implementation that reuses the same bio to write both the origin and cache device didn't take into account that the block layer's req_bio_endio() modifies a completing bio's bi_sector and bi_size. So the new writethrough strategy needs to preserve these bio fields, and restore them before submission to the cache device, otherwise nothing gets written to the cache (because bi_size is 0). This patch adds a struct dm_bio_details field to struct per_bio_data, and uses dm_bio_record() and dm_bio_restore() to ensure the bio is restored before reissuing to the cache device. Adding such a large structure to the per_bio_data is not ideal but we can improve this later, for now correctness is the important thing. This problem initially went unnoticed because the dm-cache test-suite uses a linear DM device for the dm-cache device's origin device. Writethrough worked as expected because DM submits a *clone* of the original bio, so the original bio which was reused for the cache was never touched. Signed-off-by: Darrick J.

SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever supported its use and no libc was using it, so the entire sa-restorer functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.] for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid accidental reuse of the mask bit. Upstream cdef9602 [signal: always clear sa_restorer on execve] adds code that assumes sa_sigaction has an sa_restorer field, if SA_RESTORER is defined which would break MIPS. So remove the SA_RESTORER definition before the v3.8.4 merge. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> (cherry picked from commit 17da8d63add23830892ac4dc2cbb3b5d4ffb79a8)

The commit a96102be introduced set_isa() where compatible ISA info is also set aside from the one gets passed in. It means, for example, 1004K will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like the following inappropriate: if (c->isa_level == MIPS_CPU_ISA_M32R1 || c->isa_level == MIPS_CPU_ISA_M32R2 || c->isa_level == MIPS_CPU_ISA_M64R1 || c->isa_level == MIPS_CPU_ISA_M64R2) This patch fixes it.

Commit 7517de34 ("MIPS: Alchemy: Redo PCI as platform driver") added a reference to CONFIG_DEBUG_PCI. Change it to CONFIG_PCI_DEBUG, as that is a valid Kconfig macro. Also add a newline to a debugging printk that this fix enables.
