Add glue to control the OMAP_LDP LCD as a frame buffer device using the
existing dispc.c driver under omapfb.Patch updated for mainline kernel. Note that the drivers/video/omap

For /proc/kcore, each arch registers its memory range by kclist_add().
In usual,- range of physical memory
- range of vmalloc area
- text, etc...are registered but "range of physical memory" has some troubles. It
doesn't updated at memory hotplug and it tend to include unnecessary
memory holes. Now, /proc/iomem (kernel/resource.c) includes required
physical memory range information and it's properly updated at memory
hotplug. Then, it's good to avoid using its own code(duplicating
information) and to rebuild kclist for physical memory based on
/proc/iomem.Signed-off-by: KAMEZAWA Hiroyuki

Originally, walk_memory_resource() was introduced to traverse all memory
of "System RAM" for detecting memory hotplug/unplug range. For doing so,
flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for
memory hotplug.But for using other purpose, /proc/kcore, this may includes some firmware
area marked as IORESOURCE_BUSY | IORESOUCE_MEM. This patch makes the
check strict to find out busy "System RAM".Note: PPC64 keeps their own walk_memory_resouce(), which walk through
ppc64's lmb informaton. Because old kclist_add() is called per lmb, this
patch makes no difference in behavior, finally.And this patch removes CONFIG_MEMORY_HOTPLUG check from this function.
Because pfn_valid() just show "there is memmap or not* and cannot be used
for "there is physical memory or not", this function is useful in generic
to scan physical memory range.Signed-off-by: KAMEZAWA Hiroyuki

Some 64bit arch has special segment for mapping kernel text. It should be
entried to /proc/kcore in addtion to direct-linear-map, vmalloc area.
This patch unifies KCORE_TEXT entry scattered under x86 and ia64.I'm not familiar with other archs (mips has its own even after this patch)
but range of [_stext ..._end) is a valid area of text and it's not in
direct-map area, defining CONFIG_ARCH_PROC_KCORE_TEXT is only a necessary
thing to do.Note: I left mips as it is now.

Presently, kclist_add() only eats start address and size as its arguments.
Considering to make kclist dynamically reconfigulable, it's necessary to
know which kclists are for System RAM and which are not.This patch add kclist types as
KCORE_RAM
KCORE_VMALLOC
KCORE_TEXT
KCORE_OTHERThis "type" is used in a patch following this for detecting KCORE_RAM.

PM dynamic OFF state results in context loss. That is, the host
controller has been powered off at some point, which means the registers
have been reset. The driver must detect when this happens, and restore
the context. This patch adds the means to detect context loss.Note, the PM side is not yet implemented.

gcc permitting variable length arrays makes the current construct used for
BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the
controlling expression isn't really constant. Instead, this patch makes
it so that a bit field gets used here. Consequently, those uses where the
condition isn't really constant now also need fixing.Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases
MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if
the expression is compile time constant (__builtin_constant_p() yields
true), the array is still deemed of variable length by gcc, and hence the
whole expression doesn't have the intended effect.[akpm@linux-foundation.org: make arch/sparc/include/asm/vio.h compile]

The 32-bit ptrace syscall on a 64-bit kernel (32-bit debugger on
32-bit task) behaves differently than a native 32-bit kernel. When
setting a register state of orig_eax>=0 and eax=-ERESTART* when the
debugged task is NOT on its way out of a 32-bit syscall, the task will
fail to do the syscall restart logic that it should do.Test case available at http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/erestartsys-trap.c?cvsroot=systemtap
This happens because the 32-bit ptrace syscall sets eax=0xffffffff
when it sets orig_eax>=0. The resuming task will not sign-extend this
for the -ERESTART* check because TS_COMPAT is not set. (So the task
thinks it is restarting after a 64-bit syscall, not a 32-bit one.)The fix is to have 32-bit ptrace calls set TS_COMPAT when setting
orig_eax>=0. This ensures that the 32-bit syscall restart logic
will apply when the child resumes.Signed-off-by: Roland McGrath
