7dcf2a9fce remove dummy asm/kvm.h files
This patch removes the dummy asm/kvm.h files on architectures not (yet)
supporting KVM and uses the same conditional headers installation as
already used for a.out.h .

Also removed are superfluous install rules in the s390 and x86 Kbuild
files (they are already in Kbuild.asm).

7444a72eff gpiolib: allow user-selection
This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.

b69c49b784 clean up duplicated alloc/free_thread_info
We duplicate alloc/free_thread_info defines on many platforms (the
majority uses __get_free_pages/free_pages).  This patch defines common
defines and removes these duplicated defines.
__HAVE_ARCH_THREAD_INFO_ALLOCATOR is introduced for platforms that do
something different.

* Now that ide_hwif_t instances are allocated dynamically
  the difference between MAX_HWIFS == 2 and MAX_HWIFS == 10
  is ~100 bytes (x86-32) so use MAX_HWIFS == 10 on all archs

* Define MAX_HWIFS in <linux/ide.h> instead of <asm/ide.h>.

a677a039be flag parameters: socket and socketpair
This patch adds support for flag values which are ORed to the type passwd
to socket and socketpair.  The additional code is minimal.  The flag
values in this implementation can and must match the O_* flags.  This
avoids overhead in the conversion.

The internal functions sock_alloc_fd and sock_map_fd get a new parameters
and all callers are changed.

27ac792ca0 PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures
On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:

	u64 val = PAGE_ALIGN(size);

always returns a value < 4GB even if size is greater than 4GB.

The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):

#define PAGE_SHIFT      12
#define PAGE_SIZE       (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK       (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr)       (((addr)+PAGE_SIZE-1)&PAGE_MASK)

The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.

Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

The build error is caused by the ages old gcc bug where gcc at the time of

actually can be satisfied and thus will abort unless an "r" is added to
the constraint.  For the actual code generation gcc will only ever use the
"i" constraint.

7a2852e49f [MIPS] IP28: switch to "normal" mode after PROM no longer needed
SGI-IP28 is running in so called slow mode, when kernel is started
from the PROM. PROM calls must be done in slow mode otherwise the
PROM will issue an error. To get better memory performance we now
switch to normal mode, when the PROM is no longer needed.

94daeb9069 [MIPS] Fix asm constraints for 'ins' instructions.
The third operand to 'ins' must be a constant int, not a register.

[Ralf: The bug was actually intensional.  Some versions used to throw an
error under certain circumstances for code like:

static inline void f(unsigned nr, unsigned *p)
{
	unsigned short bit = nr & 5;

	if (__builtin_constant_p(bit)) {
		__asm__ __volatile__ ("  foo %0, %1" : "=m" (*p) : "i" (bit));
  	} else {
		/* Do something else. */
	}
}

because gcc was not able to figure out that the "i" constraint was possibly
at the early stage when the constraint are getting verified.  The solution
was using "ri" instead of "i".  The "ri" would keep gcc happy but in the
end for code generation always the "i" constraint would be satisfied.  The
problem afair originally appeared in the i386 io.h and also hit it's mips
equivalent.  From there the workaround spread to many of the inline
assembler functions.]
