192d7a4667 sparc64: Fix crash with /proc/iomem
When you compile kernel on Sparc64 with heap memory checking and type
"cat /proc/iomem", you get a crash, because pointers in struct
resource are uninitialized.

Most code fills struct resource with zeros, so I assume that it is
responsibility of the caller of request_resource to initialized it,
not the responsibility of request_resource functuion.

After 2.6.29 is out, there could be a check for uninitialized fields
added to request_resource to avoid crashes like this.

d0cac39e4e sparc64: Fix lost interrupts on sun4u.
Based upon a report by Meelis Roos.

Sparc64 SBUS and PCI controllers use a combination of IMAP and ICLR
registers to manage device interrupts.

The IMAP register contains the "valid" enable bit as well as CPU
targetting information.  Whereas the ICLR register is written with
zero at the end of handling an interrupt to reset the state machine
for that interrupt to IDLE so it can be sent again.

For PCI slot and SBUS slot devices we can have multiple interrupts
sharing the same IMAP register.  There are individual ICLR registers
but only one IMAP register for managing those.

We represent each shared case with individual virtual IRQs so the
generic IRQ layer thinks there is only one user of the IRQ instance.

In such shared IMAP cases this is wrong, so if there are multiple
active users then a free_irq() call will prematurely turn off the
interrupt by clearing the Valid bit in the IMAP register even though
there are other active users.

Fix this by simply doing nothing in sun4u_disable_irq() and checking
IRQF_DISABLED during IRQ dispatch.

This situation doesn't exist in the hypervisor sun4v cases, so I left
those alone.

40bdac7dbc sparc64: Kill .fixup section bloat.
This is an implementation of a suggestion made by Chris Torek:
--------------------
Something else I noticed in passing: the EX and EX_LD/EX_ST macros
scattered throughout the various .S files make a fair bit of .fixup
code, all of which does the same thing.  At the cost of one symbol
in copy_in_user.S, you could just have one common two-instruction
retl-and-mov-1 fixup that they all share.

802c64b310 sparc64: On non-Niagara, need to touch NMI watchdog in NOHZ mode.
When we're idling in NOHZ mode, timer interrupts are not running.

Evidence of processing timer interrupts is what the NMI watchdog
uses to determine if the CPU is stuck.

On Niagara, we'll yield the cpu.  This will make the cpu, at
worst, hang out in the hypervisor until an interrupt arrives.
This will prevent the NMI watchdog timer from firing.

However on non-Niagara we just loop executing instructions
which will cause the NMI watchdog to keep firing.  It won't
see timer interrupts happening so it will think the cpu is
stuck.

Fix this by touching the NMI watchdog in the cpu idle loop
on non-Niagara machines.

arch/sparc/kernel/psycho_common.c:333: warning: long long unsigned int format, long unsigned int arg (arg 4)

This is due to different integer promotion in my 32 bit hosted gcc.
The fix is to force a few constants to ULL.

The following stands out from the rest:
+#define  PSYCHO_IOMMU_TAG_VPAGE         0x7ffffULL
+#define  PSYCHO_IOMMU_DATA_PPAGE 0xfffffffULL

They were needed otherwise the expression:

    (data_val & PSYCHO_IOMMU_DATA_PPAGE) << IOMMU_PAGE_SHIFT)

were promoted to a unsigned long and not a unsigned long long as expected.

I tried the alternative solution and made IOMMU_PAGE_SHIFT an ULL but that did not help.
The only way gcc would make this expression an unsigned long long was to
define PSYCHO_IOMMU_DATA_PPAGE as ULL. The alternative to add a cast was
not considered a valid solution.

We had this issue in two places and this were the only places the above
two constants are used.

A small coding style diff sneaked in too.

    testing it only on x86_64 and this generates a warning storm on

    Quite a few 64-bit architectures are using `long' for their
    s64/u64 types.  We should convert them all to `long long'.

Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.

This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.

4696b64d23 sparc: Fix minor SPARC32 compile error
When CONFIG_PROC_FS is unset, include/linux/interrupt.h defines
init_irq_proc() as an empty function.

arch/sparc/kernel/irq_32.c defines this function unconditionally.

Fix the latter so that it only defines this function when CONFIG_PROC_FS
is set.

This fixes the following error:
arch/sparc/kernel/irq_32.c:672: error: redefinition of 'init_irq_proc'
include/linux/interrupt.h:461: error: previous definition of
'init_irq_proc' was here

This was found using randconfig builds.

47cd5265ea sparc: Clean arch-specific code in prom_common.c
prom_nextprop() and prom_firstprop() have slightly different calling
conventions in 32 and 64 bit SPARC.

prom_common.c uses a ifdef guard to ensure that these functions are
called correctly.

Adjust code to eliminate this ifdef by using a calling convention that
is compatible with both 32 and 64 bit SPARC.

4d7b92ad57 sparc: add '32' suffix to reg_window, sigcontext, __siginfo_t
Renaming a few types to contain a 32 suffix makes the
type names compatible with sparc64 and thus makes sharing
between the two a lot easier.

Note: None of these definitions are expected part of the
stable ABI towards userspace.
