The "Synchronize Arbitration IDs with APIC IDs" IPI does not make sense
on Pentium 4 and Xeon because they don't have an APIC bus where
arbitration IDs would be needed. 

The Intel Developers manual (Vol.  3, Ch.  8.6.1) says this IPI is
unsupported on P4/Xeon.  Using it may, according to Intel, lead to
unpredictable results.

There are two issues with online io scheduler switching that this patch
addresses.  The first is pretty simple - it concerns racing with scheduler
removal on switch.  elevator_find() does not grab a reference to the io
scheduler, so before elevator_attach() is run it could go away.  Add
elevator_get() to solve that.

Second issue is the flushing out of requests that is needed before
switching can be problematic with requests that aren't allocated in the
block layer (such as requests on the stack of a process).  The problem is
that we don't know when they will have finished, and most io schedulers
need to access the elevator structures on io completion.  This can be fixed
by adding an intermedia step that switches to noop, since it doesn't need
to touch anything but the request_queue.  The queue drain can then safely
be split into two operations - one that waits for file system requests, and
one that waits for the queue to completely empty.  Requests arriving after
the first drain will get stuck in a seperate queue list.

To make spinlock/rwlock initialization consistent all over the kernel,
this patch converts explicit lock-initializers into spin_lock_init() and
rwlock_init() calls.

Currently, spinlocks and rwlocks are initialized in two different ways:

  lock = SPIN_LOCK_UNLOCKED
  spin_lock_init(&lock)

  rwlock = RW_LOCK_UNLOCKED
  rwlock_init(&rwlock)

this patch converts all explicit lock initializations to
spin_lock_init() or rwlock_init(). (Besides consistency this also helps
automatic lock validators and debugging code.)

The conversion was done with a script, it was verified manually and it
was reviewed, compiled and tested as far as possible on x86, ARM, PPC.

There is no runtime overhead or actual code change resulting out of this
patch, because spin_lock_init() and rwlock_init() are macros and are
thus equivalent to the explicit initialization method.

cdrom_is_mrw() can incorrectly think that a drive is Mt Rainier capable,
because if forgets to check if the "GET CONFIGURATION" command returns the
MRW feature number.  According to the MMC spec, the drive shall return all
feature numbers >= the starting feature number, so even if the drive
doesn't support Mt Rainier, it can return some data that makes
cdrom_is_mrw() incorrectly think the drive is MRW capable.

This problem stops me from mounting DVD+RW discs in R/W mode on my laptop,
because it makes cdrom_open_write() call cdrom_mrw_open_write() which fails
because the drive isn't really MRW capable.

The fix is to make sure the returned feature number is the correct one for
Mt Rainier.
