7edb3da: (USB: EHCI: make ehci-s5p a separate driver)
raised an issue with ehci-s5p's driver data.
Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd'
and s5p_ehci is nothing but a pointer to hcd->priv;
add hcd to the driver data rather than s5p_ehci.
This fixes issues with null pointer dereferencing in
s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().

Hi Greg,
Here's three cleanup patches for 3.10. Nothing big here, just some debugging
output changes, a macro rename, and a math macro change that should have no
behavioral effects.
Tested on the Intel Panther Point xHCI host, with USB storage and mouse, with
xHCI debugging turned on. I don't have the TI host that causes the debugging
output changes to trigger.

Separate the Qualcomm QSD/MSM on-chip 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 Qualcomm QSD/MSM
can be booted with a multi-platform kernel, which is not expected before
3.11.
With the infrastructure added by Alan Stern in patch 3e0232039
"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 msm bus glue.
In V5 (arnd):
- add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls
In V3:
- Detailed commit message added here describing why this patch is required.
- Arranged #include's in alphabetical order.
- driver.name initialized hcd_name[] = "ehci-msm" in platform_driver
structure initialization instead of "msm-ehci", which was the reason
why it broke in EHCI USB testing
In V2:

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.

"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate

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.

There are no functional changes in this patch. However, because the
compliance mode timer can be deleted in more than one function, it
seemed expedient to include the function name in the debug strings.
Also limited the use of capitals to the first word in the compliance
mode debug messages, except after a function name where all words
start with lower case, in keeping with the style prevalent elsewhere
in xhci.c.

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.

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.

"len" comes from the USB transfer and it's probably correct. The thing
is that we already have similar checks like:
if (data[i] >= serial->num_ports) {

idea.

In hardware_enqueue code adds one extra td with dma_pool_alloc if
mReq->req.zero is true. When _ep_nuke will be called for that endpoint,
dma_pool_free will not be called to free that memory again. That patch

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.

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 e2e74d617e ("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).

The dm-cache writethrough strategy introduced by commit e2e74d617e
("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.

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 cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear
sa_restorer on execve] adds code that assumes sa_sigaction has an

The commit a96102be70 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 ||

Commit 7517de3486 ("MIPS: Alchemy: Redo
