5095202603 [MIPS] Fix bug in atomic_sub_if_positive.
The branch optimization fixes in 2.6.21 introduced a bug in
atomic_sub_if_positive that causes it to return even when the sc
instruction fails. The result is that e.g. down_trylock becomes unreliable
as the semaphore counter is not always decremented.

Original MUA-shredded patch from Morten Larsen <mlarsen@broadcom.com>.

0c3bd83b09 [MIPS] Lasat: bring back from the dead
After the common MIPS CPU interrupt controller (for irq0-7) was introduced
the Lasat boards didn't get their interrupts right, so nothing worked. The
old routines need to be offset by the new 8 hardware interrupts common to
all MIPS CPU's.

- missing space between 'for' and opening parenthesis;

- macros with complex values not enclosed in parentheses;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

In addition to these changes, also do the following:

- mention DBAu1200 board in the Makefile;

- replace the group of #include/#ifdef directives by a single
  #include <au1xxx.h> since this header contains the needed stuff;

- properly indent the blocks;

- insert spaces between operator and its operands, remove excess spaces
  there;

- remove needless parentheses and add some for clarity;

- replace numeric literals/expressions with the matching macros;

- remove space after the type cast's closing parenthesis;

- reduce pb1200_setup_cascade() to the single 'return' statement;

- reduce the number of printed empty lines in the so-called CPLD
  workaround;

- remove #undef AU1X00_EXTERNAL_INT since that macro is not defined
  anywhere;

- replace spaces after the macro name with tabs in the #define directives;

- remove excess tabs after the macro name in the #define directives;

- fix typo in the BCSR_RESETS_PWMR1mUX macro's name;

- group all Pb1200 PCMCIA definitions together;

- put the function's result type and name/parameters on the same line;

- insert missing and remove excess new lines;

- make the multi-line comment style consistent with the kernel style
  elsewhere by adding empty first line and/or adding space/asterisk on
  their left side;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- combine some comments;

- update MontaVista copyright;

Rename div64_64 to div64_u64 to make it consistent with the other divide
functions, so it clearly includes the type of the divide.  Move its definition
to math64.h as currently no architecture overrides the generic implementation.
 They can still override it of course, but the duplicated declarations are
avoided.

6510d41954 kernel: Move arches to use common unaligned access
Unaligned access is ok for the following arches:
cris, m68k, mn10300, powerpc, s390, x86

Arches that use the memmove implementation for native endian, and
the byteshifting for the opposite endianness.
h8300, m32r, xtensa

Packed struct for native endian, byteshifting for other endian:
alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh

m86knommu is generic_be for Coldfire, otherwise unaligned access is ok.

frv, arm chooses endianness based on compiler settings, uses the byteshifting
versions.  Remove the unaligned trap handler from frv as it is now unused.

v850 is le, uses the byteshifting versions for both be and le.

Remove the now unused asm-generic implementation.

fcbd3b4b92 [MIPS] Pb1200/DBAu1200: move platform code to its proper place
Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:

- change 'au1200_ide0_' variable name prefix to the mere 'ide_';

- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
  name of the chip used on the boards;

- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
  on-board devices;

- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
  the macros describing the Ethernet chip for consistency with the IDE
  macros;

- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
  indeed a shift count) in the names of the macros describing the IDE
  interface.

0167509574 [MIPS] Alchemy: don't unmask timer IRQ early
Defer the unmasking of the count/compare interrupt (IRQ5) till the
clockevent driver initialization:

- only enable the cascaded IRQs 0 thru 4 in arch_init_irq(); kill the
  ALLINTS macro -- this change is blessed by AMD as I saw it in their own
  patch; :-)

- do not force IRQ5 enabled in plat_time_init() if PM is enabled and there's
  no 32 KHz crystal.

7e675137a8 mm: introduce pte_special pte bit
s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory
model (which is more dynamic than most).  Instead, they had proposed to
implement it with an additional path through vm_normal_page(), using a bit in
the pte to determine whether or not the page should be refcounted:

vm_normal_page()
{
	...
        if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) {
                if (vma->vm_flags & VM_MIXEDMAP) {
#ifdef s390
			if (!mixedmap_refcount_pte(pte))
				return NULL;
#else
                        if (!pfn_valid(pfn))
                                return NULL;
#endif
                        goto out;
                }
	...
}

This is fine, however if we are allowed to use a bit in the pte to determine
refcountedness, we can use that to _completely_ replace all the vma based
schemes.  So instead of adding more cases to the already complex vma-based
scheme, we can have a clearly seperate and simple pte-based scheme (and get
slightly better code generation in the process):

vm_normal_page()
{
#ifdef s390
	if (!mixedmap_refcount_pte(pte))
		return NULL;
	return pte_page(pte);
#else
	...
#endif
}

And finally, we may rather make this concept usable by any architecture rather
than making it s390 only, so implement a new type of pte state for this.
Unfortunately the old vma based code must stay, because some architectures may
not be able to spare pte bits.  This makes vm_normal_page a little bit more
ugly than we would like, but the 2 cases are clearly seperate.

So introduce a pte_special pte state, and use it in mm/memory.c.  It is
currently a noop for all architectures, so this doesn't actually result in any
compiled code changes to mm/memory.o.

BTW:
I haven't put vm_normal_page() into arch code as-per an earlier suggestion.
The reason is that, regardless of where vm_normal_page is actually
implemented, the *abstraction* is still exactly the same. Also, while it
depends on whether the architecture has pte_special or not, that is the
only two possible cases, and it really isn't an arch specific function --
the role of the arch code should be to provide primitive functions and
accessors with which to build the core code; pte_special does that. We do
not want architectures to know or care about vm_normal_page itself, and
we definitely don't want them being able to invent something new there
out of sight of mm/ code. If we made vm_normal_page an arch function, then
we have to make vm_insert_mixed (next patch) an arch function too. So I
don't think moving it to arch code fundamentally improves any abstractions,
while it does practically make the code more difficult to follow, for both
mm and arch developers, and easier to misuse.
