Seperates udf_sb_info from struct super_block.

Seperates isofs_sb_info from struct super_block.

I got burnt one too many time by mismatches between
the pci_pool and "real" slabs... something changed in
mm/slab.c and broke a driver, so I'm going for the real
fix this time.  Having poisoning that _works_ is a huge
help in the innards of the USB host controller drivers.

This patch gets rid of some #ifdefs and makes the pci_pool
code poison memory if CONFIG_DEBUG_SLAB is set.
The functionality has always been there, but this makes
it simpler to get at.

make driverfs initialize early, so that ACPI can come alive
in a world where you can register devices. 

into tp1.ruhr-uni-bochum.de:/home/kai/kernel/v2.5/linux-2.5.config_sound.x

For some reason the ACPI people continue to make the mistake
of thinking that they are the root of the system.  Disabuse
them of that notion.

Clean up BSD accounting locking code..

The appended patch brings the fixes applied in 2.4 to shmem.c to 2.5.

In Detail:
- Add needed checks for shmem_file_write and shmem_symlink
- Add Documentation/filesystems/tmpfs.txt and adjust Config.help
- Add uid and gid mount options
- Make the error messages more user friendly

Pick up binfmt_elf.c SET_PERSONALITY() fix from 2.4.18.

That preempt_count really is supposed to be unconditional,
architectures please take note and add to your thread info.

If you could only review one of the 9 patches, this would be the one.

- removes acpitable.c vestiges
- adds ACPI IRQ routing support to PCI (disableable via pci=noacpi option)
- adds code to get a <1MB page for sleep, and ACPI boot to setup.c
- allocates another page in the fixmap for ACPI
- changes driverfs a little to work better with ACPI.

This patch removes arch/i386/kernel/acpitable.c. As mentioned previously,
the new ACPI code integrates this, so it's no longer needed.

This updates the Configure.help, both in arch/i386, and in drivers/acpi.

This removes the old OSPM code. It lived under drivers/acpi/ospm/*, but
the new code just lives in drivers/acpi, and removes some unnecessary
abstraction that this old code had.

This is the update to the core interpreter code.

This is the config.in and makefile changes for the latest code. The most
(only) interesting thing probably is ACPI is no longer flagged experimental.

This patch updates the acpi IA32 arch-specific files. Part of this is
taking what was acpitable.c and implementing it with better integration
with the rest of the ACPI code.

This patch adds in the new drivers.

- Support for driverfs
- File/code layout more in the Linux style
- improvements to battery, processor, and thermal support

This is the first of 9 patches. We did a complete rewrite of the
Linux-specific code, so we wait for things to stabilize before submitting.
There will be more updates, but *much* smaller.

#1 - this updates the header file.

The patch below eliminates a case of boot_cpu_data corruption
on SMP x86 machines. This was first observed on SMP Athlons,
but it also affects SMP Intel boxes in a less serious way.

When the secondary processors boot and execute head.S:checkCPUtype,
the code performs a 32-bit write of a small constant to the
byte-sized variable boot_cpu_data.x86 (X86 in head.S). Since the
write is 32-bit, it also writes zeros to the following 3 bytes,
which clobbers the x86_vendor, x86_model, and x86_mask fields
previously set up by check_bugs()'s call to identify_cpu().
Thus, after smp_init(), boot_cpu_data will _always_ identify
the CPU as an Intel (X86_VENDOR_INTEL == 0 in processor.h) with
model 0 and stepping 0.

The effect in standard kernels is not catastrophic, since:
(a) most SMP x86 boxes are Intel
(b) most uses of x86_vendor occur before smp_init() or reference
    the SMP cpu_data[] array
(c) most post-boot references to boot_cpu_data occur in the
    cpu_has_XXX macros which only read the x86_capability[] array
However, third-party extensions (like my x86 performance-monitoring
conters driver) can get seriously confused by this mis-identification.

Don't print out FAT superblock warnings if the IO failed.
