hpwdt_init_nmi_decoding() is called in hpwdt_init_one error handling,
thus remove the __devexit annotation of hpwdt_exit_nmi_decoding().
This patch fixes below warning:
WARNING: drivers/watchdog/hpwdt.o(.devinit.text+0x36f): Section mismatch in reference from the function hpwdt_init_one() to the function .devexit.text:hpwdt_exit_nmi_decoding()
The function __devinit hpwdt_init_one() references
a function __devexit hpwdt_exit_nmi_decoding().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
hpwdt_exit_nmi_decoding() so it may be used outside an exit section.

So we used to use lpfn directly to restrict VRAM when we couldn't
access the unmappable area, however this was removed in
93225b0d7b as it also restricted
the gtt placements. However it was only later noticed that this
broke on some hw.
This removes the active_vram_size, and just explicitly sets it
when it changes, TTM/drm_mm will always use the real_vram_size,
and the active vram size will change the TTM size used for lpfn
setting.
We should re-work the fpfn/lpfn to per-placement at some point
I suspect, but that is too late for this kernel.
Hopefully this addresses:

We've been getting reports of complete system lockups with rv3xx hw on
AGP and PCIE when running gnome-shell or kwin with compositing.
It appears the hw really doesn't like setting these registers while
stuff is running, this moves the setting of the registers into the modeset
since they aren't required to be changed anywhere else.

This one liner patch fixes double free that will occur if add_mtd_blktrans_dev

on error which is natural thing to do. Thus don't free it.

In the commit 08968041be
(mtd: cfi_cmdset_0002: make sector erase command variable)
introdused a field sector_erase_cmd. In the same commit initialisation
of cfi->sector_erase_cmd made in cfi_chip_setup()
(file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem:
...
cfi->cfi_mode = CFI_MODE_CFI;
cfi->sector_erase_cmd = CMD(0x30);
...
But for the JEDEC chips this initialisation is not carried out,
so the JEDEC chips have sector_erase_cmd == 0.
This patch adds the missing initialisation.

Split the binding aspect of xen_allocate_pirq_msi out into a new
xen_bind_pirq_to_irq function.
In xen_hvm_setup_msi_irq when allocating a pirq write the MSI message
to signal the PIRQ as soon as the pirq is obtained. There is no way to
free the pirq back so if the subsequent binding to an IRQ fails we
want to ensure that we will reuse the PIRQ next time rather than leak
it.

The find_unbound_pirq is called only from xen_allocate_pirq_msi and
only if alloc_pirq is true. The only caller which does this is
xen_hvm_setup_msi_irqs. The use of this function is gated, in
pci_xen_hvm_init, on XENFEAT_hvm_pirqs.
The PHYSDEVOP_get_free_pirq interfaces was added to the hypervisor in
22410:be96f6058c05 while XENFEAT_hvm_pirqs was added a couple of
minutes prior in 22409:6663214f06ac. Therefore we do not need to
concern ourselves with hypervisors which support XENFEAT_hvm_pirqs but
not PHYSDEVOP_get_free_pirq.
This eliminates the fallback path in find_unbound_pirq which walks to
pirq_to_irq array looking for a free pirq. Unlike the
PHYSDEVOP_get_free_pirq interface this fallback only looks up a free
pirq but does not reserve it. Removing this fallback will simplify
locking in the future.
