When re-applying the configuration after a successful usb device reset,
xhci_discover_or_reset_device has already dropped the endpoints, and free-ed
the rings.
The endpoints already being dropped is expected, and should not lead to
warnings. Use the fact that the rings are also free-ed in this scenario to
detect this, and suppress the "xHCI xhci_drop_endpoint called with disabled
ep ..." message in this case.

The USB stack provides a mechanism for drivers to request an
asynchronous device reset (usb_queue_reset_device()). The mechanism
uses a work item (reset_ws) embedded in the usb_interface structure
used by the driver, and the reset is carried out by a work queue
routine.
The asynchronous reset can race with driver unbinding. When this
happens, we try to cancel the queued reset before unbinding the
driver, on the theory that the driver won't care about any resets once
it is unbound.
However, thanks to the fact that lockdep now tracks work queue
accesses, this can provoke a lockdep warning in situations where the
device reset causes another interface's driver to be unbound; see
http://marc.info/?l=linux-usb&m=141893165203776&w=2
for an example. The reason is that the work routine for reset_ws in
one interface calls cancel_queued_work() for the reset_ws in another
interface. Lockdep thinks this might lead to a work routine trying to
cancel itself. The simplest solution is not to cancel queued resets
when unbinding drivers.
This means we now need to acquire a reference to the usb_interface
when queuing a reset_ws work item and to drop the reference when the
work routine finishes. We also need to make sure that the
usb_interface structure doesn't outlive its parent usb_device; this
means acquiring and dropping a reference when the interface is created
and destroyed.
In addition, cancelling a queued reset can fail (if the device is in
the middle of an earlier reset), and this can cause usb_reset_device()
to try to rebind an interface that has been deallocated (see
http://marc.info/?l=linux-usb&m=142175717016628&w=2 for details).
Acquiring the extra references prevents this failure.

because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.
It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.
Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

We altered the device tree bindings for the Nomadik family of
pin controllers to be standard, this file was merged out-of-order
so we missed fixing this. Fix it up.

Merge "omap fixes against v3.19-rc1" from Tony Lindgren:
Fixes for omaps mostly to deal with dra7 timer issues
and hypervisor mode. The other fixes are minor fixes for
various boards. The summary of the fixes is:
- Fix real-time counter rate typos for some frequencies
- Fix counter frequency drift for am572x
- Fix booting of secondary CPU in HYP mode
- Fix n900 board name for legacy user space
- Fix cpufreq in omap2plus_defconfig after Kconfig change
- Fix dra7 qspi partitions
And also, let's re-enable smc91x on some n900 boards that
we have sitting in a few test boot systems after the boot
loader dependencies got fixed.

Merge "ARM: imx: fixes for 3.19" from Shawn Guo:
The i.MX fixes for 3.19:
- One fix for incorrect i.MX25 SPI1 clock assignment in device tree,
which causes system hang when accessing SPI1.
- Correct i.MX6SX QSPI parent clock configuration to fix a kernel Oops.
- Fix ULPI PHY reset modelling on imx51-babbage board to remove the
dependency on bootloader for USB3317 ULPI PHY reset.
- Correct video divider setting on i.MX6Q rev T0 1.0 to fix the issue
that HDMI is not working at high resolution on T0 1.0.
- One incremental fix for CODA960 VPU enabling in device tree to
correct interrupt order.
- LS1021A SCFG block works in BE mode, add device tree property
big-endian to make it right.

Avoid overflow possibility.
[ The overflow is purely theoretical, since this is used for memory
ranges that aren't even close to using the full 64 bits, but this is
the right thing to do regardless. - Linus ]

dwfl_report_offline() works only when libraries are prelinked.
Replace dwfl_report_offline() with dwfl_report_elf() so we correctly
extract debug info even from libraries that are not prelinked.

Currently the symbol structure is allocated with symbol_conf.priv_size
to carry sideband information like annotation, map browser on TUI and
sort-by-name tree node. So retrieving these information from symbol
needs to care about the details of such placement.
However the annotation code just assumes that the symbol is placed after
the struct annotation. But actually there's other info between them.
So accessing those struct will lead to an undefined behavior (usually a
crash) after they write their info to the same location.
To reproduce the problem, please follow the steps below:
1. run perf report (TUI of course) with -v option
2. open map browser (by pressing right arrow key for any entry)
3. search any function (by pressing '/' key and input whatever..)
4. return to the hist browser (by pressing 'q' or left arrow key)
5. open annotation window for the same entry (by pressing 'a' key)

Perf tool fails to unwind user stack if the event raises in a shared
object. This patch improves tests/dwarf-unwind.c to demonstrate the
problem by utilizing commonly used glibc function "bsearch". If perf is
not statically linked, the testcase will try to unwind a mixed call
trace.
By debugging libunwind I found that there is a bug in unwind-libunwind:
it always passes 0 as segbase to libunwind, cause libunwind unable to
locate debug_frame entry fir first level ip address (I add some more
debugging output into libunwind to make things clear):
>_Uarm_dwarf_find_debug_frame: start_ip = 10be98, end_ip = 10c2a4
>_Uarm_dwarf_find_debug_frame: found debug_frame table `/lib/libc-2.18.so': segbase=0x0, len=7, gp=0x0, table_data=0x449388
>_Uarm_dwarf_search_unwind_table: call lookup:ip = b6cd3bcc, segbase = 0, rel_ip = b6cd3bcc
>lookup: e->start_ip_offset = bcf18 (rel_ip = b6cd3bcc)
>lookup: e->start_ip_offset = 6d314 (rel_ip = b6cd3bcc)

...
>lookup: e->start_ip_offset = 15d0c (rel_ip = b6cd3bcc)
>lookup: e->start_ip_offset = 15c40 (rel_ip = b6cd3bcc)
>_Uarm_dwarf_search_unwind_table: IP b6cd3bcc inside range b6c12000-b6d4c000, but no explicit unwind info found

This patch passes map->start as segbase to dwarf_find_debug_frame(), so
di will be initialized correctly.
In addition, dso and executable are different when setting segbase. This
patch first check whether the elf is executable, and pass segbase only
for shared object.

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...
