If hard_irq_disable() is called while interrupts are already soft-disabled
(which is the most common case) all is already well.
However you can (and in some cases want) to call it while everything is
enabled (to make sure you don't get a lazy even, for example before entry
into KVM guests) and in this case we need to inform the irq tracer that
the irqs are going off.
We have to change the inline into a macro to avoid an include circular
dependency hell hole.

The value passed is 0 in all but "it can never happen" cases (and those

After the device names are created using PLATFORM_DEVID_AUTO, the old

The updates are mostly about the x86 IOMMUs this time. Exceptions are
the groundwork for the PAMU IOMMU from Freescale (for a PPC platform)
and an extension to the IOMMU group interface. On the x86 side this
includes a workaround for VT-d to disable interrupt remapping on broken
chipsets. On the AMD-Vi side the most important new feature is a kernel
command-line interface to override broken information in IVRS ACPI
tables and get interrupt remapping working this way. Besides that there
are small fixes all over the place.

This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the
assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore
some data alignments for PAGE_SIZE have been limited to 4K (or less) to
not waste too much memory with greater page sizes. As a side note, the
palo loader can (currently) only handle up to 10 ELF segments which is
fixed with tighter aligning as well.
My testings indicated that the ldci command in the sba iommu coding
needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page
size was only set to 4K for my machine (C3000).
All this fixes partly the boot, but there are still quite some caching
problems left. Examples are e.g. the symbios logic driver which is
failing:
sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69
sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking
CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED.
and the tulip network driver which doesn't seem to work correctly
either:
Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1
link partner capability of 05e1
..... timed out!
Beside those kernel fixes glibc will need fixes too to be able to handle
>4K page sizes.

Pull CIFS fixes from Steve French:
"A set of cifs cleanup fixes.
The only big one of this set optimizes the cifs error logging,
renaming cFYI and cERROR macros to cifs_dbg, and in the process makes
it clearer and reduces module size."
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
cifs: small variable name cleanup
CIFS: fix error return code in cifs_atomic_open()
cifs: store the real expected sequence number in the mid
cifs: on send failure, readjust server sequence number downward
cifs: remove ENOSPC handling in smb_sendv
[CIFS] cifs: Rename cERROR and cFYI to cifs_dbg
fs: cifs: use kmemdup instead of kmalloc + memcpy
cifs: replaced kmalloc + memset with kzalloc
cifs: ignore the unc= and prefixpath= mount options
When checking if an autofs mount point is busy it isn't sufficient to
only check if it's a mount point.
For example, if the mount of an offset mountpoint in a tree is denied
for this host by its export and the dentry becomes a process working
directory the check incorrectly returns the mount as not in use at
expire.
This can happen since the default when mounting within a tree is
nostrict, which means ingnore mount fails on mounts within the tree and
continue. The nostrict option is meant to allow mounting in this case.

When unloading the driver that drives an EISA board, a message similar to the
following one is displayed:
Trying to free nonexistent resource <0000000000013000-000000000001301f>
Then an user is unable to reload the driver because the resource it requested in
the previous load hasn't been freed. This happens most probably due to a typo in
vortex_eisa_remove() which calls release_region() with 'dev->base_addr' instead
of 'edev->base_addr'...

The inline path seems to have changed the SLAB behavior for very large
kmalloc allocations with commit e3366016 ("slab: Use common
kmalloc_index/kmalloc_size functions"). This patch restores the old
behavior but also adds diagnostics so that we can figure where in the
code these large allocations occur.

The PCI core supports an offset per aperture nowadays but our arch
code still has a single offset per host bridge representing the
difference betwen CPU memory addresses and PCI MMIO addresses.
This is a problem as new machines and hypervisor versions are
coming out where the 64-bit windows will have a different offset
(basically mapped 1:1) from the 32-bit windows.
This fixes it by using separate offsets. In the long run, we probably
want to get rid of that intermediary struct pci_controller and have
those directly stored into the pci_host_bridge as they are parsed
but this will be a more invasive change.

Some devices don't have a correct node ID and thus can't be
attached to an iommu.
The message displayed by the iommu code isn't very useful if
you don't have a device-tree node as it tries to print the
device-tree path but not the struct device name.
Improve this by printing the device name as well.
