The patch below by Roland McGrath fixes two bugs in the implementation of
the selinux_file_mprotect hook:

  It calls selinux_file_mmap, which has two problems.  First, the stacked
  security module will get both mmap and mprotect callbacks for an
  mprotect call, which is wrong.  Secondly, the vm_flags value contains 
  VM_* bits, and these do not match the MAP_* bits of the same name or
  function, so it passes bogus flags and causes every mprotect to be 
  treated as if MAP_SHARED were in use.

  The patch shares the common code while not having one function call the
  other, and fixes these two bugs.

Derive process start times from the posix_clock_monotonic notion of uptime
instead of "jiffies", consistent with the earlier change to /proc/uptime
itself.
(http://linus.bkbits.net:8080/linux-2.5/cset@3ef4851dGg0fxX58R9Zv8SIq9fzNmQ?na%0Av=index.html|src/.|src/fs|src/fs/proc|related/fs/proc/proc_misc.c)

Process start times are reported to userspace in units of 1/USER_HZ since
boot, thus applications as procps need the value of "uptime" to convert
them into absolute time.

Currently "uptime" is derived from an ntp-corrected time base, but process
start time is derived from the free-running "jiffies" counter.  This
results in inaccurate, drifting process start times as seen by the user,
even if the exported number stays constant, because the users notion of
"jiffies" changes in time.

It's John Stultz's patch anyways, which I only messed up a bit, but since

This patch is for removing obsolete system calls from m32r kernel, such as 
old_mmap and old_select.

	* arch/m32r/kernel/entry.S:
	- Remove an obsolete system call, old_mmap, from the syscall table.

	* arch/m32r/kernel/sys_m32r.c:
	- Remove obsolete system calls, old_mmap() and old_select().
	- do_mmap2() is renamed to sys_mmap2().

* CAUTION (for m32r users):
  The new kernel (applied this patch) does not have a backward
  compatibility. The new kernel and old library pair does not work.

  So, those who want to use the new kernel must use a new version of 
  glibc (the GNU C library), which uses the "mmap2(_NR_mmap2)" syscall
  for __mmap() instead of the "old_mmap(__NR_mmap)".

  The new glibc package, libc6_2.3.2.ds1-16.0.3_m32r.deb, is provided
  on the following site, please apt-get/download it and upgrade.

  according to the interpolator resolution since this causes periodic timer
  signals to fail.  The clocks will still be high-resolution but the
  "resolution" reported reflects the timer intervals possible via
  timer_settime (also more conformant to what the Single Unix Specification
  says).

- Make the IA64 clock_gettime fastcall fall back on negative clock

Fixes a data corruption issue. Because of a typo in the driver, IO packets
were wrongly shared by the IOCTL path. This caused the whole IO command
to be replaced by an incoming IOCTL command.

ACPI still explodes on my old PII and stops it booting.

Anyway, it is oopsing in drivers/acpi/scan.c line 207 where element
(which is NULL) gets dereferenced.

The ACPI bios on this thing has always seemed to be pretty broken, but
this at least allows the 'power' button to continue to work (the only
reason why I want ACPI).

As spotted by one of our Fedora users, we sometimes
oops during shutdown (http://www.roberthancock.com/kerneloops.png)
because disable_IO_APIC() wants to call find_isa_irq_pin(),
which we threw away during init.

http://bugzilla.kernel.org/show_bug.cgi?id=3238

This is made possible by the previous resource allocation ordering
patch.

Now that we run the pre-existing PCI resource discovery _before_
ACPI resources have been added, we should not "insert" the resources
into any existing tree. If they clash with existing resources, we
should re-allocate them (later, when we have the full resource map).

This re-orders the PCI and ACPI IO resource assignment as suggested by
Linus.

With this patch, now the sequence of reserving resources is:
 1. PCI claim BAR
 2. ACPI reserve motherboard resources
 3. PNP reserve motherboard resources
 4. PCI allocate resources for uninitialized PCI devices

This way the kernel allocates new PCI resources after it has full
knowledge of the resource state, and at the same time allows ACPI and
PnP to be run _after_ we've filled in our knowledge about pre-allocated
resources. 

The way it is done is to make the last phase of the original PCI assign
resources code to be an 'fs_initcall', along with the ACPI and PnP
initializations.

From: Jens Axboe <axboe@suse.de>

The blacklist stuff is broken. When set_using_dma() calls into
->ide_dma_check(), it returns __ide_dma_off() for a blacklisted drive.
This of course succeeds, returning success to the caller of ->ide_dma_check().
Not so good... It then uncondtionally calls ->ide_dma_on(), which turns on
DMA for the drive.

This moves the check to __ide_dma_on() so we also catch the buggy
->ide_dma_check() defined by various chipset drivers.
