efb4a44e24 ARM: dts: socfpga: Add a 3.3V fixed regulator node
Without the 3.3V regulator node, the SDMMC driver will give these warnings:

dw_mmc ff704000.dwmmc0: No vmmc regulator found
dw_mmc ff704000.dwmmc0: No vqmmc regulator found

This patch adds the regulator node, and points the SD/MMC to the regulator.

v3: Rename nodes to have schematic-name_regulator and remove "boot-on" and
    "always-on"
v2: Move the regulator nodes to their respective board dts file and
    correctly rename them to match the schematic

23920c0552 ARM: dts: socfpga: Fix SD card detect
Without this patch, the booting the SOCFPGA platform would hang at the
SDMMC driver loading. The issue, debugged by Doug Anderson, turned out
to be that the GPIO bank used by the SD card-detect was not set to
status="okay".

Also update the cd-gpios to point to portb of the &gpio1 GPIO IP.

d11ac1d2d5 ARM: dts: socfpga: rename gpio nodes
Since the Synopsys GPIO IP can support multiple ports of varying widths, it
would make more sense to have the GPIO node DTS entry as this:

gpio0: gpio@ff708000{
	porta{
	};
};

Also, this is documented in the snps-dwapb-gpio.txt.

271a9c3515 uprobes: Remove "weak" from function declarations
For the following interfaces:

  set_swbp()
  set_orig_insn()
  is_swbp_insn()
  is_trap_insn()
  uprobe_get_swbp_addr()
  arch_uprobe_ignore()
  arch_uprobe_copy_ixol()

kernel/events/uprobes.c provides default definitions explicitly marked
"weak".  Some architectures provide their own definitions intended to
override the defaults, but the "weak" attribute on the declarations applied
to the arch definitions as well, so the linker chose one based on link
order (see 10629d711e ("PCI: Remove __weak annotation from
pcibios_get_phb_of_node decl")).

Remove the "weak" attribute from the declarations so we always prefer a
non-weak definition over the weak one, independent of link order.

9e0f162a36 MIPS: tlbex: Properly fix HUGE TLB Refill exception handler
In commit 8393c524a2 (MIPS: tlbex: Fix a missing statement for
HUGETLB), the TLB Refill handler was fixed so that non-OCTEON targets
would work properly with huge pages.  The change was incorrect in that
it broke the OCTEON case.

The problem is shown here:

    xxx0:	df7a0000 	ld	k0,0(k1)
    .
    .
    .
    xxxc0:	df610000 	ld	at,0(k1)
    xxxc4:	335a0ff0 	andi	k0,k0,0xff0
    xxxc8:	e825ffcd 	bbit1	at,0x5,0x0
    xxxcc:	003ad82d 	daddu	k1,at,k0
    .
    .
    .

In the non-octeon case there is a destructive test for the huge PTE
bit, and then at 0, $k0 is reloaded (that is what the 8393c524a2
patch added).

In the octeon case, we modify k1 in the branch delay slot, but we
never need k0 again, so the new load is not needed, but since k1 is
modified, if we do the load, we load from a garbage location and then
get a nested TLB Refill, which is seen in userspace as either SIGBUS
or SIGSEGV (depending on the garbage).

The real fix is to only do this reloading if it is needed, and never
where it is harmful.

by the HW when the settings have been taken into use.

The current PLL code handles this wrong: instead of waiting for the bit
to be cleared, it waits for the bit to be set. Usually, the bit is
always set, as the CPU has just set it before. However, if the CPU takes
enough time between setting the GO bit and checking it, the HW may
already have cleared the bit and this leads to timeout error.

Fix the wait to check the bit properly.

13a0c40a49 OMAPFB: fix releasing overlays
omapfb disables all the overlays when freeing resources, but it should
also remove those overlays from overlay managers.

Not doing so causes a crash if omapfb is unbound and bound, or omapfb
module is removed and loaded, while keeping omapdss around.

Fix this by calling unset_manager() for all overlays.

63cec5a22c OMAPFB: fix overlay disable when freeing resources.
When omapfb is shutting down, it will disable all the overlays. However,
instead of actually disabling all the overlays, it disables only all the
overlays that are currently attached to framebuffers.

On OMAP4+, this leaves the fourth overlay left enabled.

Fix the loop so that we actually go through all the overlays.

422ccbd571 OMAPDSS: set suppress_bind_attrs
omapdss drivers cannot handle devices being unbound while the devices
are part of a connected display pipeline. Module refcounts are used to
prevent unloading the modules, but one can still manually unbind the
devices via sysfs, causing crash.

Set suppress_bind_attrs to disable the bind/unbind support via sysfs.

37773c4e7f fbcon: Fix option parsing control flow in fb_console_setup
Since strsep is used to tokenize the options string, after each option
match the code should use "continue" to get the next token from strsep.
This patch applies this pattern consistently.

Previously, for "scrollback:" and "map:" the parse code would return
(unconditionally: strsep ensures *options != ','), causing any
following option to be ignored, while for "vc:" the parse code would
go on to parse further options within the same token, which could lead
to invalid input being accepted.

Remove the check of CONFIG_PPC_SUBPAGE_PROT when deciding if
is_hugepage_only_range() is extern or inline. The extern version is in
slice.c and is built if CONFIG_PPC_MM_SLICES=y.

There was no build break possible because CONFIG_PPC_SUBPAGE_PROT is
only selectable under conditions which also mean CONFIG_PPC_MM_SLICES
will be selected.
