[PATCH] Sanely size hash tables when using large base pages
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:
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.

[PATCH] KVM: Improve interrupt response
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.

In this case the libata quirk code reserves the resources in question

[PATCH] KVM: Fix oops on oom
__free_page() doesn't like a NULL argument, so check before calling it. A
NULL can only happen if memory is exhausted during allocation of a memory
slot.

The latest version of kvm doesn't initialize kvm_arch_ops in kvm_init(), which
causes an error with the following sequence.
1. Load the supported arch's module.
2. Load the unsupported arch's module.\e$B!!\e(B(loading error)
3. Unload the unsupported arch's module.
You'll get the following error message after step 3. "BUG: unable to handle
to handle kernel paging request at virtual address xxxxxxxx"
The problem here is that the unsupported arch's module overwrites kvm_arch_ops
of the supported arch's module at step 2.
This patch initializes kvm_arch_ops upon loading architecture specific kvm
module, and prevents overwriting kvm_arch_ops when kvm_arch_ops is already set
correctly.

[PATCH] PIIX: remove check for broken MW DMA mode 0
There's no need to check in piix_config_drive_for_dma() for broken MW DMA
mode 0 as this mode is not supported by the driver (it sets
hwif->mwdma_mask to 0x6), and hence can't be selected by ide_dma_speed().
(Alan sayeth "Probably right but if not you've got a subtle corruptor. Should
at least stick a BUG_ON mode 0 setting right close when the mode is set.")

Russel King recently reminded us that one shouldn't use asm/arch/hardware.h
but one should use asm/hardware.h. Unfortunately, the spi_s3c24xx_gpio
driver is using the wrong header. This patch is fixing that.
