Merge tag 'trace-fixes-v3.10-rc3-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing fixes from Steven Rostedt:
 "This contains 4 fixes.

  The first two fix the case where full RCU debugging is enabled,
  enabling function tracing causes a live lock of the system.  This is
  due to the added debug checks in rcu_dereference_raw() that is used by
  the function tracer.  These checks are also traced by the function
  tracer as well as cause enough overhead to the function tracer to slow
  down the system enough that the time to finish an interrupt can take
  longer than when the next interrupt is triggered, causing a live lock
  from the timer interrupt.

  Talking this over with Paul McKenney, we came up with a fix that adds
  a new rcu_dereference_raw_notrace() that does not perform these added
  checks, and let the function tracer use that.

  The third commit fixes a failed compile when branch tracing is
  enabled, due to the conversion of the trace_test_buffer() selftest
  that the branch trace wasn't converted for.

  The forth patch fixes a bug caught by the RCU lockdep code where a
  rcu_read_lock() is performed when rcu is disabled (either going to or
  from idle, or user space).  This happened on the irqsoff tracer as it
  calls task_uid().  The fix here was to use current_uid() when possible
  that doesn't use rcu locking.  Which luckily, is always used when
  irqsoff calls this code."

Commit 9f29ab11 ("ACPI / scan: do not match drivers against objects
having scan handlers") introduced a boot regression on Tony's ia64 HP
rx2600.  Tony says:

  "It panics with the message:

   Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel

   [...] my problem comes from arch/ia64/hp/common/sba_iommu.c
   where the code in sba_init() says:

        acpi_bus_register_driver(&acpi_sba_ioc_driver);
        if (!ioc_list) {

   but because of this change we never managed to call ioc_init()
   so ioc_list doesn't get set up, and we die."

Revert it to avoid this breakage and we'll fix the problem it attempted
to address later.

From Shawn Guo, mxs fixes for 3.10:

- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
  interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
  valid interrupt number, the irq of gpio bank 0.  That unnecessary
  polling results in the driver not detecting when irq 0x7f is active
  which makes the machine effectively dead lock.  The fix removes the
  interrupt poll loop and allows usage of gpio0 interrupt without an
  infinite loop.

From Shawn Guo, imx fixes for 3.10, take 2:

- One device tree fix for all spi node to have per clock added.
  The clock is needed by spi driver to calculate bit rate divisor.
  The spi node in the current device trees either does not have the
  clock or is defined as dummy clock, in which case the driver probe
  will fail or spi will run at a wrong bit rate.

- Two imx6q clock fixes, which correct axi_sels and ldb_di_sels.

If the early MMU mapping of the UART happens to get booted out of the
TLB between the start of paging_init() and when we finally re-add the
UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if
we've got early_printk enabled.  Avoid this hang by calling
debug_ll_io_init() early.

Without this patch, you can reliably reproduce a hang when early
printk is enabled by adding flush_tlb_all() at the start of
exynos_init_io().  After this patch the hang goes away.

Merge tag 'renesas-fixes-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes

From Simon Horman, Renesas ARM based SoC fixes for v3.10:
- Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
  This avoids conflicts when the USB_OVCn pins are used by another function.
  This has been observed to be a problem in v3.10-rc1.
- Update CMT clock rating for sh73a0 SoC to resolve boot failure
  on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1.

Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.

Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.

With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.
