73069e388d ARM: OMAP: Fix gpio by switching to generic gpio calls, v2
Fix compile by removing remaining omap specific gpio
calls. Based on earlier patches by Jarkko Nikula.

Also remove old GPIO key code, there is already a patch
to do this with gpio_keys.

5cca0cf15a x86, pat: fix reserve_memtype() for legacy 1MB range
Thierry Vignaud reported:

> On P4 with an SiS motherboard (video card is a SiS 651)

Here X is trying to map first 8KB of memory using /dev/mem. Existing
code treats first 0-4KB of memory as non-RAM and 4KB-8KB as RAM. Recent
code changes don't allow to map memory with different attributes
at the same time.

Fix this by treating the first 1MB legacy region as special and always
track the attribute requests with in this region using linear linked
list (and don't bother if the range is RAM or non-RAM or mixed)

6c9789de2a powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-Boots
FSL U-Boots use /soc8315@e0000000 node to search and fixup serial
nodes' clock-frequency properties. Though in upstream kernels we use
new naming convention -- for IMMR address space dts files specify
/immr@e0000000 nodes.

This makes FSL U-Boots fail to fixup the clock frequencies, and that
leads to serial ports misbehaviour. We can workaround the issue by
filling the clock frequency values manually.

p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for
ethernet nodes, so users should either change the .dts file locally
or set MAC address via `ifconfig hw ether' command.

58dab916df x86 PAT: remove CPA WARN_ON for zero pte
Impact: reduce scope of debug check - avoid warnings

The logic to find whether identity map exists or not using
high_memory or max_low_pfn_mapped/max_pfn_mapped are not complete
as the memory withing the range may not be mapped if there is a
unusable hole in e820.

Specifically, on my test system I started seeing these warnings with
tools like hwinfo, acpidump trying to map ACPI region.

We can add logic to check for this. But, there can also be other holes in
identity map when we have 1GB of aligned reserved space in e820.

This patch handles it by removing the WARN_ON and returning a specific
error value (EFAULT) to indicate that the address does not have any
identity mapping.

The code that tries to keep identity map in sync can ignore
this error, with other callers of cpa still getting error here.

cdecff6864 x86 PAT: return compatible mapping to remap_pfn_range callers
Impact: avoid warning message, potentially solve 3D performance regression

Change x86 PAT code to return compatible memtype if the exact memtype that
was requested in remap_pfn_rage and friends is not available due to some
conflict.

This is done by returning the compatible type in pgprot parameter of
track_pfn_vma_new(), and the caller uses that memtype for page table.

Note that track_pfn_vma_copy() which is basically called during fork gets the
prot from existing page table and should not have any conflict. Hence we use
strict memtype check there and do not allow compatible memtypes.

This patch fixes the bug reported here:

  http://marc.info/?l=linux-kernel&m=123108883716357&w=2

Specifically the error message:

  X:5010 map pfn expected mapping type write-back for d0000000-d0101000,
  got write-combining

Should go away.

c8399943bd x86, generic: mark complex bitops.h inlines as __always_inline
Impact: reduce kernel image size

Hugh Dickins noticed that older gcc versions when the kernel
is built for code size didn't inline some of the bitops.

Mark all complex x86 bitops that have more than a single
asm statement or two as always inline to avoid this problem.

Probably should be done for other architectures too.

Ingo then found a better fix that only requires
a single line change, but it unfortunately only
works on gcc 4.3.

On older gccs the original patch still makes a ~0.3% defconfig
difference with CONFIG_OPTIMIZE_INLINING=y.

With gcc 4.1 and a defconfig like build:

    6116998 1138540  883788 8139326  7c323e vmlinux-oi-with-patch
    6137043 1138540  883788 8159371  7c808b vmlinux-optimize-inlining

~20k / 0.3% difference.

c478b58135 powerpc/powermac: Fix occasional SMP boot failure
The PowerMac kernel occasionally fails to bring up the secondary CPUs on
SMP, the trigger factor seem to be fairly random and related to location
of code and data.

This appears to be due to the initial loading of the TOC value by the
secondary processor which now happens before we clear HID4:RM_CI (Real
Mode Cache Invalidate). This bit should really be cleared before we do
any load or store other than fetching code.

This fix works based on the assumption that all SMP 64-bit PowerMacs use
variants of the 970, which fortunately is true, by explicitely clearing
that bit, adding an slbia for good measure as RM_CI mode is known to
create bogus ERAT entries.

I also removed some spurrious debug output that was left enabled by
mistake while at it.

Enforce that the crash kernel region never overlaps the current kernel,
as it will be written directly on kexec load.

Also, default to the previous KDUMP_KERNELBASE if the start is 0.

Other architectures (x86, ia64) state that specifying the start address
0 (or omitting it) will result in the kernel allocating it.  Before the
relocatable patch in 2.6.28, powerpc would adjust any other start value
to the hardcoded KDUMP_KERNELBASE of 32M.

6ec9eae67a [WATCHDOG] Enable watchdog timer on GE Fanuc's SBC610
Support for the FPGA based watchdog timer on GE Fanuc's SBC610.

This patch enables one of the watchdog timers found on the SBC610. There are
two identical watchdog timers at different offsets in the above mentioned
boards, however the current driver is only capable of supporting one of them.

The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.

50c668d678 Revert "cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write"
This reverts commit 7503bfbae8.

Dieter Ries reported bootup soft-hangs and bisected it back to
this commit, and reverting this commit gave him a working system.

The commit introduces work_on_cpu() use into the cpufreq code,
but that is subtly problematic from a lock hierarchy POV: the
hotplug-cpu lock is an highlevel lock that is taken before
lowlevel locks, and in this codepath we are called with the
policy lock taken.

Dieter did not have lockdep enabled so we dont have a nice stack
trace proof for this, but using work_on_cpu() in such a lowlevel
place certainly looks wrong, so we revert the patch.

work_on_cpu() needs to be reworked to be more generally usable.

f313e12308 x86: avoid theoretical vmalloc fault loop
Ajith Kumar noticed:

 I was going through the vmalloc fault handling for x86_64 and am unclear
 about the following lines in the vmalloc_fault() function.

 pgd = pgd_offset(current->mm ?: &init_mm, address);
 pgd_ref = pgd_offset_k(address);

 Here the intention is to get the pgd corresponding to the current process
 and sync it up with the pgd in init_mm(obtained from pgd_offset_k).
 However, for kernel threads current->mm is NULL and hence pgd =
 pgd_offset(init_mm, address) = pgd_ref which means the fault handler
 returns without setting the pgd entry in the MM structure in the context
 of which the kernel thread has faulted.  This could lead to never-ending
 faults and busy looping of kernel threads like pdflush.  So, shouldn't the
 pgd = pgd_offset(current->mm ?: &init_mm, address); be pgd =
 pgd_offset(current->active_mm ?: &init_mm, address);

We can use active_mm unconditionally because it should be always set.

Replace the current sysctl-based suspend interface with a new sysfs-
based one which also uses the Linux-2.6 suspend model.

To configure wakeup sources, a subtree for the demoboards is created
under /sys/power/db1x:

sys/
`-- power
    `-- db1x
        |-- gpio0
        |-- gpio1
        |-- gpio2
        |-- gpio3
        |-- gpio4
        |-- gpio5
        |-- gpio6
        |-- gpio7
        |-- timer
        |-- timer_timeout
        |-- wakemsk
        `-- wakesrc

The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2
bits of the SYS_WAKEMSK (wakeup source enable) register.  Writing '1'
enables a wakesource, 0 disables it.

The 'timer_timeout' node holds the timeout in seconds after which the
TOYMATCH2 event should wake the system.

The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex),
the 'wakemsk' node can be used to get/set the wakeup mask directly.

For example, to have the timer wake the system after 10 seconds of sleep,
the following must be done in userspace:

echo 10 > /sys/power/db1x/timer_timeout
echo 1 > /sys/power/db1x/timer
echo mem > /sys/power/sleep

This patch also removes the homebrew CPU frequency switching code.  I don't
understand how it could have ever worked reliably; it does not communicate
the clock changes to peripheral devices other than uarts.

779e7d41ad MIPS: make cp0 counter clocksource/event usable as fallback.
The current mips clock build infrastructure lets a system only use
either the MIPS cp0 counter or a SoC specific timer as a clocksource /
clockevent device.

This patch renames the core cp0 counter clocksource / clockevent functions
from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to
call these renamed functions instead.

Chips which can detect whether it is safe to use a chip-specific timer
can now fall back on the cp0 counter if necessary and possible
(e.g. Alchemy with a follow-on patch).

Existing behaviour is not changed in any way.

Remove the cpu_table:
- move detection of whether c0_config[OD] is read-only and should be set
  to fix various chip errata to au1000 headers.
- move detection of write-only sys_cpupll to au1000 headers.
- remove the BCLK switching code:  Activation of this features should be
  left to the boards using the chips since it also affects external devices
  tied to BCLK, and only the board designers know whether it is safe to
  enable.

785e3268e2 MIPS: Alchemy: update core interrupt code.
This patch attempts to modernize core Alchemy interrupt handling code.

- add irq_chips for irq controllers instead of irq type,
- add a set_type() hook to change irq trigger type during runtime,
- add a set_wake() hook to control GPIO0..7 based wakeup,
- use linux' IRQF_TRIGGER_ constants instead of homebrew ones,
- enable GENERIC_HARDIRQS_NO__DO_IRQ.
- simplify plat_irq_dispatch
- merge au1xxx_irqmap into irq.c file, the only place where its
  contents are referenced.
- board_init_irq() is now mandatory for every board; use it to register
  the remaining (gpio-based) interrupt sources; update all boards
  accordingly.

Run-tested on Db1200 and other Au1200 based platforms.

58f07778ce MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon/executive and asm/octeon.
These files are used to coordinate resource sharing between all of
the programs running on the OCTEON SOC.  The OCTEON processor has many
CPU cores (current parts have up to 16, but more are possible).  It
also has a variety of on-chip hardware blocks for things like network
acceleration, encryption and RAID.

One typical configuration is to run Linux on several of the CPU cores,
and other dedicated applications on the other cores.

Resource allocation between the various programs running on the system
(Linux kernel and other dedicated applications) needs to be
coordinated.  The code we use to do this we call the 'executive'.  All
of this resource allocation and sharing code is gathered together in
the executive directory.

Included in the patch set are the following files:

cvmx-bootmem.c and cvmx-sysinfo.c -- Coordinate memory allocation.
All memory used by the Linux kernel is obtained here at boot time.

cvmx-l2c.c -- Coordinates operations on the shared level 2 cache.

octeon-model.c  -- Probes chip capabilities and version.

The corresponding headers are in asm/octeon.

2bd2dd059c MIPS: Alchemy: Change strict_strtol to strict_strtoul
Since memsize is unsigned, it would seem better to use strict_strtoul that
strict_strtol.

A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// <smpl>

8659c406ad x86: only scan the root bus in early PCI quirks
We found a situation on Linus' machine that the Nvidia timer quirk hit on
a Intel chipset system.  The problem is that the system has a fancy Nvidia
card with an own PCI bridge, and the early-quirks code looking for any
NVidia bridge triggered on it incorrectly.  This didn't lead a boot
failure by luck, but the timer routing code selecting the wrong timer
first and some ugly messages.  It might lead to real problems on other
systems.

I checked all the devices which are currently checked for by early_quirks
and it turns out they are all located in the root bus zero.

So change the early-quirks loop to only scan bus 0.  This incidently also
saves quite some unnecessary scanning work, because early_quirks doesn't
go through all the non root busses.

The graphics card is not on bus 0, so it is not matched anymore.

   a. 32/64X address mismatch
   b. The 32/64X FACS address mismatch

   In such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.

   In such case we should use the bit[7:4] of Cx address to check whether
the Cx type is supported or not.

Removed all the includes that are no longer needed in sparc_ksyms_32.c

Comment all remaining EXPORT_SYMBOL()s in sparc_ksyms_32.c

Two symbols are shared with sparc64 thus the exports were removed from
the sparc_ksyms_64.c too, along with the include their ommission made
redundant.

45536ffc8d sparc: Create a new file lib/ksyms.c and add export of all symbols defined in assembler in lib/ to this file.
Remove the duplicate entries from kernel/sparc_ksyms_*.c

The rationale behind this is that the EXPORT_SYMBOL() should be close to
their definition and we cannot add designate a symbol to be exported in
assembler so at least put it in a file in the same directory.

e8dc7c4882 sparc64: fix warnings in psycho_common after ull conversion
After conversion to use unsigned long long for u64
I saw following warnings:

arch/sparc/kernel/psycho_common.c:333: warning: long long unsigned int format, long unsigned int arg (arg 4)

This is due to different integer promotion in my 32 bit hosted gcc.
The fix is to force a few constants to ULL.

The following stands out from the rest:
+#define  PSYCHO_IOMMU_TAG_VPAGE         0x7ffffULL
+#define  PSYCHO_IOMMU_DATA_PPAGE 0xfffffffULL

They were needed otherwise the expression:

    (data_val & PSYCHO_IOMMU_DATA_PPAGE) << IOMMU_PAGE_SHIFT)

were promoted to a unsigned long and not a unsigned long long as expected.

I tried the alternative solution and made IOMMU_PAGE_SHIFT an ULL but that did not help.
The only way gcc would make this expression an unsigned long long was to
define PSYCHO_IOMMU_DATA_PPAGE as ULL. The alternative to add a cast was
not considered a valid solution.

We had this issue in two places and this were the only places the above
two constants are used.

A small coding style diff sneaked in too.
