29b9a218d0 omap: pass the reboot command to the boot loader
This patch follows the commit be093beb60
by Russell King:

  OMAP wishes to pass state to the boot loader upon reboot in order
  to instruct it whether to wait for USB-based reflashing or not.
  There is already a facility to do this via the reboot() syscall,
  except we ignore the string passed to machine_restart().

The patch adds the missing parameter to omap1_arch_reset() and
omap_prcm_arch_reset(), and modifies the latter to pass the reboot
command parameter to the boot loader instead of reboot mode (which is
for kernel internal use only and cannot be modified by the userspace).

f0dc117abd IPoIB: Fix TX queue lockup with mixed UD/CM traffic
The IPoIB UD QP reports send completions to priv->send_cq, which is
usually left unarmed; it only gets armed when the number of
outstanding send requests reaches the size of the TX queue. This
arming is done only in the send path for the UD QP.  However, when
sending CM packets, the net queue may be stopped for the same reasons
but no measures are taken to recover the UD path from a lockup.

Consider this scenario: a host sends high rate of both CM and UD
packets, with a TX queue length of N.  If at some time the number of
outstanding UD packets is more than N/2 and the overall outstanding
packets is N-1, and CM sends a packet (making the number of
outstanding sends equal N), the TX queue will be stopped.  When all
the CM packets complete, the number of outstanding packets will still
be higher than N/2 so the TX queue will not be restarted.

Fix this by calling ib_req_notify_cq() when the queue is stopped in
the CM path.

79cf5bff25 omap2: Update n8x0 defconfig to test multi-omap and DMA api changes
Recent DMA API changes broke compile for tusb6010. While
testing the fixes for tusb6010, I had to update the n8x0
defconfig quite a bit. Might as well merge it while at it
to make it more usable as we're using this to test the
multi-omap booting between V6 and V7 ARMs.

Also, anybody using n8x0 with a current kernel will most
likely want to mount root on the MMC instead of the onenand
to keep the Maemo install intact.

Enable I2C, REGULATOR, MMC, MFD, PM, and USB. Also change the root
to /dev/mmcblk0p2 instead of the onenand.

6f69a1815a omap2/3/4: ehci: avoid compiler error with touchbook
the early_param() call in board-omap3touchbook.c expands to:

static const char __setup_str_early_touchbook_revision[]
	__section(.init.rodata) _aligned(1) = tbr;
[...]

and we have a non-const variable being added to the
same section:

static struct ehci_hcd_omap_platform_data ehci_pdata
__section(.init.rodata);

because of that, gcc generates a section type conflict
which can (and actually should) be avoided by marking
const every variable marked with __initconst.

This patch fixes that for the ehci_hdc_omap_platform_data.

<...>-1987  [019]   280.252837: x86_pmu_start: event-51/1300c0: idx: 32 *FAIL*

This happens because we only iterate the n_running events in the first
pass, and reset their index to -1 if they don't match to force a
re-assignment.

Now, in our RR example, n_running == 0 because we fully unscheduled, so
event-50 will retain its idx==32, even though in scheduling it will have
gotten idx=0, and we don't trigger the re-assign path.

The easiest way to fix this is the below patch, which simply validates
the full assignment in the second pass.

noMMU uses UNCACHE SHADOW feature where is used double ram size.
For example:
Physical ram is 256MB and cache are setup to cover the same size.
But if you setup in HW that size is 512MB and cache covers 256MB
than you can use adresses from 256-512MB without caches and
correspond with 0-256MB with cache. That's why I am using

137d0795a7 microblaze: Change temp register for cmdline
For copy was used r7 register when CONFIG_CMDLINE_BOOL option
is enabled. But r7 stores pointer to fdt that's why machine_early_init
not detect compiled-in DTB.

I also moved kernel PID setup to have TLB init in one block

7ae5f21361 perf: Make the install relative to DESTDIR if specified
Without this change, the install path is relative to
prefix/DESTDIR where prefix is automatically set to $HOME.

This can produce unexpected results. For example:

  make -C tools/perf DESTDIR=/home/jkacur/tmp install-man

creates the directory:		/home/jkacur/home/jkacur/tmp/share/...
instead of the expected:	/home/jkacur/tmp/share/...

From : Ananth N Mavinakayanahalli <ananth@in.ibm.com>

When freeing the instruction slot, the arithmetic to calculate
the index of the slot in the page needs to account for the total
size of the instruction on the various architectures.

Calculate the index correctly when freeing the out-of-line
execution slot.

a6475c1322 microblaze: Enable PCI, missing files
There are two parts of changes. The first is just enable
PCI in Makefiles and in Kconfig. The second is the rest of
missing files. I didn't want to add it with previous patch
because that patch is too big.

Current Microblaze toolchain has problem with weak symbols
that's why is necessary to apply this changes to be possible
to compile pci support.
Xilinx knows about this problem.
