[PATCH] fix split_vma vs. invalidate_mmap_range_list race
From: "V. Rajesh" <vrajesh@eecs.umich.edu>
If a vma is already present in an i_mmap list of a mapping,
then it is racy to update the vm_start, vm_end, and vm_pgoff
members of the vma without holding the mapping's i_shared_sem.
This is because the updates can race with invalidate_mmap_range_list.
I audited all the places that assign vm_start, vm_end, and vm_pgoff.
AFAIK, the following is the list of questionable places:
1) This patch fixes the racy split_vma. Kernel 2.4 does the
right thing, but the following changesets introduced a race.

[PATCH] Allow more APIC irq sources
The "irq_vector[]" array is indexed by the sum of all RTEs in all I/O
APICs, and is not necessarily limited by the x86 CPU irq vector inputs.
In fact, the irq vector index would overflow on big machines with lots
of IO APIC's, causing the boot to fail.
So grow the array for the big SMP boxes, keeping the default the same as
before (and shrink the vector entry size down to a 8-bit value, since
that's the size of the actual CPU vector entry).

[PATCH] Fix initrd with devfs enabled
This fixes initrd with devfs. With that combination the late-boot code
does temporary mount of devfs over rootfs /dev, which made /dev/initrd
inaccessible. For setups without devfs that didn't happen.
The fix is trivial - put the file in question outside of /dev; IOW,
we simply replace "/dev/initrd" with "/initrd.image" in init/*.

[PATCH] md - Use sector rather than block numbers when splitting raid0 requests.
When raid0 needs to split a request, it uses 'block' (1K) addresses

address is odd. This patch fixes the problem.
[PATCH] fix drivers/ide/pci/siimage.c for PROC_FS=n
From: "Noah J. Misch" <noah@caltech.edu>
The Silicon Image driver is not building properly when CONFIG_PROC_FS is unset.
This patch corrects that problem. It appears as though several utility
functions at the top of drivers/ide/pci/siimage.c that the driver always needs
accidentally fell within an #ifdef CONFIG_PROC_FS. I also removed an excess
include while I noticed it.

[PATCH] ia64: zero out topology related sysfs nodes
Tony pointed out (thanks Tony) that in -test8 kobject_set_name() will
try to free a kobject's k_name field if it's non-NULL, so we need to
zero it out in case kmalloc() gave us recycled memory or we'll try to
kfree a bogus area.
There's a hole at 0xa0000-0xc0000, so we should ignore all the WB memory
in that granule. With 16MB granules, the existing code trims like this
(note the 4K page at 0x0 should have been ignored, but wasn't).
They were added by Torben to workaround ServerWorks driver problems
(fixed by previous patch), but depending on BIOS can be dangerous on
other chipsets and it is always better to fix specific driver.
If PIO mode should be auto-tuned xferspeed argument for svwks_tune_chipset()
is equal to 255 (0xFF). It is then passed to ide_rate_filter() which matches
desired mode with chipset capabilities. Since 255 is greater than any of the
values used for transfer modes, ide_rate_filter() will always return the
highest mode supported by both device/chipset (which sometimes should not be
used ie. when host is a simplex one) and the wrong mode will be set.
Thanks to Torben Mathiasen and Tomas Szepe for testing it.

Software Developer's Manual page 2:270, section 11.3.2.3

This patch re-uses the same min-state area that the PAL/SAL

deleting code and declarations (some of which were wrong,
MIN_STATE_AREA_SIZE ought to have been 58). The real "work"
is copying the pointer to the min-state area from the

[PATCH] drivers/block/initrd.c removal
From: viro@parcelfarce.linux.theplanet.co.uk
* drivers/block/initrd.c gone
* chunk of memory where the current tree would look for intird image is
checked for being a valid initramfs image first; then, it is either
unpacked (in addition to normal built-in image) or, if it wasn't a valid
image, copied into a regular file on rootfs called /dev/initrd. Then
memory is freed.
Result:
a) we can put initramfs image in place of initrd one and kernel will DTRT.
b) initrd images still work as usual; code that shoves the thing to
ramdisk, etc. doesn't care whether it reads from a block device or
regular file.
c) initrd.c is gone, so is fake block device and a lot of irregularities
with it.
It has been in -mm for almost two weeks with no reported problems.
