72a7fe3967 Introduce flags for reserve_bootmem()
This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.

This patch:

Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past.  This is to avoid conflicts.

Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().

- Always include the architecture dependent Kconfig files.
- Wrap architecture dependent Kconfig files inside an appropriate

This makes it possible to run the configuration even without the arch links,
which are created later in the build process.

4d672e7ac7 timerfd: new timerfd API
This is the new timerfd API as it is implemented by the following patch:

int timerfd_create(int clockid, int flags);
int timerfd_settime(int ufd, int flags,
		    const struct itimerspec *utmr,
		    struct itimerspec *otmr);
int timerfd_gettime(int ufd, struct itimerspec *otmr);

The timerfd_create() API creates an un-programmed timerfd fd.  The "clockid"
parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.

The timerfd_settime() API give new settings by the timerfd fd, by optionally
retrieving the previous expiration time (in case the "otmr" parameter is not
NULL).

The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit
is set in the "flags" parameter.  Otherwise it's a relative time.

The timerfd_gettime() API returns the next expiration time of the timer, or
{0, 0} if the timerfd has not been set yet.

Like the previous timerfd API implementation, read(2) and poll(2) are
supported (with the same interface).  Here's a simple test program I used to
exercise the new timerfd APIs:

52840bd628 Kobject: the cris iop_fw_load.c code is broken
This code is really really really broken.  So much so that it's almost
impossible to fix with a simple patch, so just comment out the offending
registration with the kobject core, and mark the driver as broken.

The problem is that the code is trying to register a "raw" struct
device, which is not allowed.  struct device is only for use within the
driver model.  This is being done to try to use the firmware layer which
wants a struct device.  To properly fix this, use something easy, like a
platform device, which is a struct device and can be used for this kind
of thing.

b0e86f0a3b CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common defines
- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD.
  The reservation up to page size of memory after init data was previously
  not done if BLK_DEV_INITRD was undefined.
  This caused a kernel oops when init memory pages were freed after startup,
  data placed in the same page as the last init memory would also be freed
  and reused, with disastrous results.

- Use macros for initcalls and .text sections.

- Replace hardcoded page size constant with PAGE_SIZE define.

- Change include/asm-cris/page.h to use the _AC macro to instead
  of testing __ASSEMBLY__.

Remove MTD_AMDSTD and MTD_OBSOLETE_CHIPS from defconfig, Kconfig and code,
instead we'll use MTD_CFI or MTD_JEDECPROBE.

7b275523ab cris build fixes: corrected and improved NMI and IRQ handling
Corrects compile errors and the following:

- Remove oldset parameter from do_signal and do_notify_resume.

- Modified to fit new consolidated IRQ handling code.

- Reverse check order between external nmi and watchdog nmi to avoid false
  watchdog oops in case of a glitch on the nmi pin.

- Return from an pin-generated NMI the same way as for other interrupts.

- Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
  low-level asm interrupt handlers.  Fixed in the multiple interrupt
  handler also.

- Add space for thread local storage in thread_info struct.

- Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
  independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
  rtc and pci.

01dd2fbf0d typo fixes
Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

09cadedbdc Combine instrumentation menus in kernel/Kconfig.instrumentation
Quoting Randy:

"It seems sad that this patch sources Kconfig.marker, a 7-line file,
20-something times.  Yes, you (we) don't want to put those 7 lines into
20-something different files, so sourcing is the right thing.

However, what you did for avr32 seems more on the right track to me: make
_one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
and MARKERS and then use (source) that in all of the arches."

cba4fbbff2 remove include/asm-*/ipc.h
All asm/ipc.h files do only #include <asm-generic/ipc.h>.

This patch therefore removes all include/asm-*/ipc.h files and moves the
contents of include/asm-generic/ipc.h to include/linux/ipc.h.
