At the moment the inode/dentry cache hash tables (common by way of
alloc_large_system_hash()) are incorrectly sized by their respective
detection logic when we attempt to use large base pages on systems with
little memory.
This results in odd behaviour when using a 64kB PAGE_SIZE, such as:
Dentry cache hash table entries: 8192 (order: -1, 32768 bytes)
Inode-cache hash table entries: 4096 (order: -2, 16384 bytes)
The mount cache hash table is seemingly the only one that gets this right
by directly taking PAGE_SIZE in to account.
The following patch attempts to catch the bogus values and round it up to
at least 0-order.

o Relocatable bzImage support had got rid of CONFIG_PHYSICAL_START option
thinking that now this option is not required as people can build a
second kernel as relocatable and load it anywhere. So need of compiling
the kernel for a custom address was gone. But Magnus uses vmlinux images
for second kernel in Xen environment and he wants to continue to use
it.
o Restoring the CONFIG_PHYSICAL_START option for the time being. I think
down the line we can get rid of it.

In the kernels later than 2.6.19 there is a regression that makes swsusp
fail if the resume device is not explicitly specified.
It can be fixed by adding an additional parameter to
mm/swapfile.c:swap_type_of() allowing us to pass the (struct block_device
*) corresponding to the first available swap back to the caller.

When the old IDE layer calls into methods in the driver during error
handling it is essentially random whether ide_lock is already held. This
causes a deadlock in the atiixp driver which also uses ide_lock internally
for locking.
Switch to a private lock instead.

Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667
This is because the packet driver tries to send down read/write BLOCK_PC
commands that don't use a bio and do not use sg lists.
The right fix is to replace all the packet_command stuff in the packet
driver by scsi_execute() which needs to be lifted from scsi code to
the block code for that.
Fix the bug for now. It's not the full way to a generic execute block pc
infrastcuture but fixes the bug for the time being.

The current interrupt injection mechanism might delay an interrupt under
the following circumstances:
- if injection fails because the guest is not interruptible (rflags.IF clear,
or after a 'mov ss' or 'sti' instruction). Userspace can check rflags,
but the other cases or not testable under the current API.
- if injection fails because of a fault during delivery. This probably
never happens under normal guests.
- if injection fails due to a physical interrupt causing a vmexit so that
it can be handled by the host.
In all cases the guest proceeds without processing the interrupt, reducing
the interactive feel and interrupt throughput of the guest.
This patch fixes the situation by allowing userspace to request an exit
when the 'interrupt window' opens, so that it can re-inject the interrupt
at the right time. Guest interactivity is very visibly improved.

KVM does kmalloc() in an atomic section while having preemption disabled via
vcpu_load(). Fix this by moving the ->*_msr setup from the vcpu_setup method
to the vcpu_create method.
(This is also a small speedup for setting up a vcpu, which can in theory be
more frequent than the vcpu_create method).

This patch fixes 2.6.15 regression, is straightforward and tested.
Cable detection got broken probably while converting the driver to support
multiple controllers. Cable detection is done by examining how BIOS
configured the attached devices. The current code is broken in that it
examines the status *after* modifying Clk66 configuration ending up
detecting 40c cables as 80c. This patch fixes it.

The pci_find_subsys gets called very early by obsolete ide setup parameters.
This is a bogus call since pci is not initialized yet, so the list is empty.
But in the mean time, interrupts get enabled by down_read. This can result in
a kernel panic when the irq controller gets initialized.
This patch checks if the device list is empty before taking the semaphore, and
hence will not enable irq's. Furthermore it will inform that it is called
while pci_devices is empty as a reminder that the ide code needs to be fixed.
The pci_get_subsys can get called in the same manner, and as such is patched
in the same manner.

irq's are not supposed to be enabled (Particularly the ide kernel parameters).

The calls made by parse_parms to other initialization code might enable
interrupts again way too early.
Having interrupts on this early can make systems PANIC when they initialize
the IRQ controllers (which happens later in the code). This patch detects
that irq's are enabled again, barfs about it and disables them again as a
safety net.

It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens. We
default to 5 seconds, which sometimes is a bit too short.
Jeremy Higdon reported here:
http://lkml.org/lkml/2007/1/1/145
that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.
So just do the sane thing and change the default command timeout to 7
seconds to avoid other surprises.
