Patch from Lennert Buytenhek

Hi,

gcc doesn't understand 80-bit floating point on the ARM currently,
according to the kernel's Kconfig docs, but it would seem that the
current extended double emulation code is broken for big endian
platforms.

So, this patch disables NWFPE_XP on big endian architectures, until
someone comes round and fixes it.

Patch from Lennert Buytenhek

Hi,

I need the patch below (against 2.6.8-rc1-ds1) to make nwfpe properly
emulate arithmetic with doubles on a big endian ARM platform.

From reading the mailing list archives and from helpful comments I've
received from people on this list, I gather that this has come up in
the past, but it appears that Russell King was never really convinced
as to why this patch is needed.  I think I understand what's going on,
and will try to explain.

On little endian ARM, the double value 1.0 looks like this when stored
in memory in FPA word ordering:
bytes: 0x00 0x00 0xf0 0x3f 0x00 0x00 0x00 0x00
u32s:  0x3ff00000 0x00000000
u64:   0x000000003ff00000

On big endian, it looks like this:
bytes: 0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
u32s:  0x3ff00000 0x00000000
u64:   0x3ff0000000000000

It appears to be this way because once upon a time, somebody decided
that the sub-words of a double will use native endian word ordering
within themselves, but the two separate words will always be stored
with the most significant one first.  God knows why they did it this
way, but they did.

Anyway.  The key observation is that nwfpe internally stores double
values in the type 'float64', which is basically just a typedef for
unsigned long long.  It never accesses 'float64's on the byte level
by casting pointers around or anything like that, it just uses direct
u64 arithmetic primitives (add, shift, or, and) for float64
manipulations and that's it.

So.  For little endian platforms, 1.0 looks like:
0x00 0x00 0xf0 0x3f 0x00 0x00 0x00 0x00
But since nwfpe treats it as a u64, it wants it to look like:
0x00 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f
So, that's why the current code swaps the words around when getting
doubles from userspace and putting them back (see fpa11_cpdt.c,
loadDouble and storeDouble.)

On big endian, 1.0 looks like:
0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
Since nwfpe treats it as a u64, it wants it to look like:
0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
Hey!  That's exactly the same.  So in this case, it shouldn't be
swapping the halves around.  However, it currently does that swapping
unconditionally, and that's why floating point emulation messes up.

This is how I understand things -- hope it makes sense to other people
too.


cheers,
Lennert

Patch from Ben Dooks

Fixes missing IRQ_TICK from RTC resources

Patch from Ben Dooks

Updated all arch/arm/mach-s3c2410/mach-XXX.c files to
register default set of devices

Added new board struct to keep this sort of info, as it
isn't possible to register platform_devices until after
the init_io functions have been called.

Patch from Ben Dooks

Added clock definition for watchdog, and fixed it so
that clocks that cannot be enabled/disabled will be
left alone.

Fixed typo in naming of clocks when registering

The following patch implements a pci_remove_bus() that can be used by
hotplug drivers for the removal of root buses.  It also defines a
release function that frees the device struct for pci_bus->bridge when a
root bus class device is unregistered.

This patch changes all the i2c chip drivers and documentation to use the
name "cpu0_vid" instead of "in0_ref". The name "in0_ref" was an error in
the first place as motherboard manufacturers may fail to follow the chip
manufacturer's recommendation about which "in" channel to use for VCore
monitoring.

The new name leaves room for chips able to monitor more than 1 vid
value, such as the LM93 and, to a lesser extent, the PC87360 family (all
by National Semiconductor). These chips are typically designed for
dual-CPU motherboards.

This breaks the interface (obviously) so libsensors has been updated to
support both names.

Add support for a couple of BIOS ROM devices.

The patch has been committed to the MTD CVS tree and adds entries to
jedec_probe.c for AMD AM29F002T, Hyundai HY29F002T and Macronix
MX29F002T parts.

This version is slightly updated from the previous once since I
accidentally added MANUFACTURER_MACRONIX when it already existed.  I
also moved the new definitions to go along with the alphabetical by

The second part adresses a problem of resetting the max cpu-freq when

multiplier in the clock_ratio[] table to longhault_table[] cause the
longhaul_setstate function works with the clock_ratio[] index.
                                                                                                          
Changing the while loop to a for loop with upper limit isn't actually
necessary as long as the driver is bug free, but thats IMHO not yet the
case, so I suggest this change in order to not loop endlessly or read
beyond the limits of the clock_ratio array.

here's a patch that solves some issues I have with the longhaul cpufreq
driver on my epia 6000CL/Via EDEN (actually reporting as CentaurHauls,
family 6, model 7, VIA Samuel 2). The driver tries to compute the fsb speed
while it could actually use the fixed values (as it does for model == 6).
I got this change from the via forum, so no credits to me.
