Remove BINFMT_ELF32 config option. Support should be always compiled in if
CONFIG_COMPAT is set.Cc: Martin Schwidefsky

Currently most architectures either always build binfmt_elf32 in the kernel
image or make it a boolean option. Only sparc64 and s390 allow to build it
modularly. This patch turns the option into a boolean aswell because elf
requires various symbols that shouldn't be available to modules. The most
urgent one is tasklist_lock whos export this patch series kills, but there
are others like force_sgi aswell.Note that sparc doesn't allow a modular 32bit a.out handler either, and
that would be the more useful case as only few people want 32bit sunos
compatibility and 99.9% of all sparc64 users need 32bit linux native elf
support.Signed-off-by: Christoph Hellwig

Currently the snsc driver uses force_sig to send init a SIGPWR when the
system overheats. This patch switches it to kill_proc instead which has
the following advantages:(1) gets rid of one of the last remaining tasklist_lock users
in modular code
(2) simplifies the snsc code significantlyThe downside is that an init implementation could in theory block SIGPWR
and it would not get delivered. The sysvinit code used by all major
distributions doesn't do this and blocking this signal in init would be a
rather stupid thing to do.Signed-off-by: Christoph Hellwig

- Switch from register_chrdev() to (register|alloc)_chrdev_region().
- use a cdev. This was intended for original patchset, but was
overlooked.We use a single cdev for all pins (minor device-numbers), as gleaned
from cs5535_gpio, and in contrast to whats currently done in scx200_gpio
(which I'll fix soon)Signed-off-by: Jim Cromie

Fix module-init-func by repairing usage of platform_device_del/put in
module-exit-func. IOW, it imitates Ingo's 'mishaps' patch, which fixed the
module-init-func's undo handling.Also fixes lack of release_region to undo the earlier registration.
Also starts to 'use a cdev' which was originally intended (its present in
scx200_gpio). Code compiles and runs, exhibits a lesser error than
previously. (re-register-chrdev fails)Since I had to add "include ", I went ahead and made 2
tweaks that fell into diff-context-window:
- remove include everyone's doing it
- copyright updates - current date is 'wrong'Signed-off-by: Jim Cromie

Add LED Class device support for the Soekris net48xx Error LED. Tested
only on a net4801, but should work on a net4826 as well. I'd love to find
a way of detecting a Soekris net48xx device but there is no DMI or any
Soekris-specific PCI devices.[akpm@osdl.org: fixlets, cleanups]

Newer ARMs have a 40 bit physical address space, but mapping physical
memory above 4G needs a special page table format which we (currently?) do
not use for userspace mappings, so what happens instead is that mapping an
address >= 4G will happily discard the upper bits and wrap.There is a valid_mmap_phys_addr_range() arch hook where we could check for
>= 4G addresses and deny the mapping, but this hook takes an unsigned long
address:static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size);
And drivers/char/mem.c:mmap_mem() calls it like this:
static int mmap_mem(struct file * file, struct vm_area_struct * vma)
{
size_t size = vma->vm_end - vma->vm_start;if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size))
So that's not much help either.
This patch makes the hook take a pfn instead of a phys address.

When EDAC was first introduced into the kernel it had a sysfs interface,
but due to some problems it was disabled in 2.6.16 and remained disabled in
2.6.17.With feedback, several of the control and attribute files of that interface
had some good constructive feedback. PCI Blacklist/Whitelist was a major
set which has design issues and it has been removed in this patch. Instead
of storing PCI broken parity status in EDAC, it has been moved to the
pci_dev structure itself by a previous PCI patch. A future patch will
enable that feature in EDAC by utilizing the pci_dev info.The sysfs is now enabled in this patch, with a minimal set of control and
attribute files for examining EDAC state and for enabling/disabling the
memory and PCI operations.The Documentation for EDAC has also been updated to reflect the new state
of EDAC operation.Signed-off-by:Doug Thompson

When UML is built as a static binary, it segfaults when run. The reason is
that a memory hole that is present in dynamic binaries isn't there in static
binaries, and it contains essential stuff.This fix removes the code which maps some anonymous memory into that hole and
cleans up some related code.Signed-off-by: Jeff Dike

This cleans up the mess that is the timer initialization. There used to be
two timer handlers - one that basically ran during delay loop calibration and
one that handled the timer afterwards. There were also two sets of timer
initialization code - one that starts in user code and calls into the kernel
side of the house, and one that starts in kernel code and calls user code.This eliminates one timer handler and consolidates the two sets of
initialization code.[akpm@osdl.org: use new INTF_ flags]

I was looking at the code of the UML and more precisely at the functions
set_task_sizes_tt and set_task_sizes_skas. I noticed that these 2 functions
take a paramater (arg) which is not used : the function is always called with
the value 0.I suppose that this value might change in the future (or even can be
configured), so I added a constant in mem_user.h file.Also, I rounded CONFIG_HOST_TASk_SIZE to a 4M.
