  Starting at around 2.6.4-rc2-mm1, I keep seeing 'scripts/fixdep: Text
  file busy' messages when doing a -j10 bzImage build - which seems to
  suggest that by the time fixdep is used by the build system it's not
  built yet.

I was pretty sure it was something I had caused, so I gave it a spin.  What
actually happened was that we tried to build the target 'silentoldconfig'
in parrallel with 'scripts'.  Since 'silentoldconfig' started a new make
and then the config target needed 'scripts' we saw two parallel runs.

The way I decided to fix it was to split scripts/ in two parts.  The first
part is now the very basic stuff - moved to scripts/basic/.  The second
part is dependent on kernel config etc.  and kept in scripts/

In the 2.7 timeframe i will redo this initial stuff - it's becoming too
messy for anyone to understand today.


Description:

Fix dependencies in early phases of kernel build.  This solves a few
problems nively: modpost is no longer rebuild twicewhen reaching the
'target' state 'make -j10' now works nicely again

The patch is rather large due to the following file moves:
mkdir scripts/basic
mv scripts/fixdep.c        scripts/basic
mv scripts/split-include.c scripts/basic
mv scripts/docproc.c       scripts/basic

The g5 iommu code would fill the "iommu_table" member of whatever
device node was pointed to by pcidev->sysdata during boot. However,
the ppc64 kernel fills that with a pointer to the PHB node which is
later replaced "lazily" with a pointer to the real node when calling
pci_device_to_OF_node(). In this case, we were thus "losign" the
iommu_table pointer. Typical symptom: loss of the SATA when looking
at it's /proc entry.

This fixes it by forcing the update to the final sysdata pointer
when filling up the iommu_table pointers. The "lazy" thing is useless
on pmac anyway.

SN2 platforms provide oemdata in salinfo records.  The decode of that
oemdata is done via prom routines.  This patch provides the interface
from user space through the kernel into the prom to do the oem decode.

Apparently GCC sometimes fails to insert a stop-bit when re-using p14
after the spinlock directives, even though the register is clearly marked
as "clobbered".

Use the proper (and cleaner) probing API instead of the old
scsi_module.c hack, don't use the typedefs I plan to kill in 2.7 and
mark everything static

This Kconfig patch basically just makes ia64 look a little more like i386:
        - moves system type above processor type
        - moves PM & ACPI to a new top-level menu
        - moves PCI/PCMCIA to a new top-level menu

See this ChangeSet:

http://lia64.bkbits.net:8080/linux-ia64-2.4/cset@40524248tkgE0RDYQL0IyiAdFxo_Ew

The MCA code is now slim enough that there isn't much point in keeping
CONFIG_IA64_MCA anymore.

The patch that moved and renamed consistent_dma_mask neglected
to fix up arch/ia64/hp/common/sba_iommu.c.

The last mod to fix the staircase printing - missed some bracing...

This fixes the CONFIG_DEBUG_INFO build on x86-64 (there were missing
.cfi_endprocs)

Also some minor cleanup in the exception stack handling.

There's an error in sys_swapon() that can cause slab corruption if you
pass in a bad specialfile pointer. getname() then returns
ERR_PTR(-EFAULT), but sys_swapon() doesn't clear name before calling
putname() on it (thus freeing 0xfffffff2, corrupting slab). An ltp test
case repeatedly crashed in later tests due to thus, irk.

This bug was discussed on linux-scsi a few weeks back, but it appears to
have slipped through the cracks. This fix was originally proposed by
Christoph Hellwig, but I am reposting it, since I have the hardware :-)

Anyway, the problem that this fixes is that megaraid doesn't set the
moduler owner for the host_template, this means that the module can be
removed, even when it is in use.

If the driver fails to load, we leave a 3c509 eisa directory
in sysfs.

No code changes, but lots of trivial whitespace cleaning, and
removal of a bogus set of 'defaults' at the bottom of the file.

Patch from Adrian Bunk

Patch from Bjorn Helgaas

ACPI and HCDP tell us what IRQ the serial port uses, so there's
no need to have the driver probe for the IRQ.

Adds a generic implementation of 32 bit emulation for IPC system calls.  The
code is based on the existing implementations for sparc64, ia64, mips, s390,
ppc and x86_64, which can subsequently be converted to use this.

This patch declares all possible functions static.

Based on the kobject structure, but much smaller and simpler to use.
