Revert commit 85e72aa538 ("proc: clear_refs: do not clear reserved
pages"), which was a quick fix suitable for -stable until ARM had been
moved over to the gate_vma mechanism:
https://lkml.org/lkml/2012/1/14/55
With commit f9d4861f ("ARM: 7294/1: vectors: use gate_vma for vectors user
mapping"), ARM does now use the gate_vma, so the PageReserved check can be
removed from the proc code.

This fixes the below reported false lockdep warning. e096d0c7e2
("lockdep: Add helper function for dir vs file i_mutex annotation") added
a similar annotation for every other inode in hugetlbfs but missed the
root inode because it was allocated by a separate function.
For HugeTLB fs we allow taking i_mutex in mmap. HugeTLB fs doesn't
support file write and its file read callback is modified in a05b0855fd
("hugetlbfs: avoid taking i_mutex from hugetlbfs_read()") to not take
i_mutex. Hence for HugeTLB fs with regular files we really don't take
i_mutex with mmap_sem held.

Due to new supported hardware, of which the actual temperature limits of
processor, harddisk and other components are unknown, it feels safer with
lower fanon / fanoff settings.
It won't change much for most people, already using acerhdf, as they use
their own fanon/fanoff variable settings when loading the module.
Furthermore seems like kernel and userspace tools have been improved to
work more efficient and netbooks don't get so hot anymore.

While stressing the kernel with with failing allocations today, I hit the
following chain of events:
alloc_page_buffers():
bh = alloc_buffer_head(GFP_NOFS);
if (!bh)
goto no_grow; <= path taken
grow_dev_page():
bh = alloc_page_buffers(page, size, 0);
if (!bh)
goto failed; <= taken, consequence of the above
and then the failed path BUG()s the kernel.
The failure is inserted a litte bit artificially, but even then, I see no
reason why it should be deemed impossible in a real box.
Even though this is not a condition that we expect to see around every
time, failed allocations are expected to be handled, and BUG() sounds just
too much. As a matter of fact, grow_dev_page() can return NULL just fine
in other circumstances, so I propose we just remove it, then.

The comments above __alloc_bootmem_node() claim that the code will
first try the allocation using 'goal' and if that fails it will
try again but with the 'goal' requirement dropped.
Unfortunately, this is not what the code does, so fix it to do so.
This is important for nobootmem conversions to architectures such
as sparc where MAX_DMA_ADDRESS is infinity.
On such architectures all of the allocations done by generic spots,
such as the sparse-vmemmap implementation, will pass in:
__pa(MAX_DMA_ADDRESS)
as the goal, and with the limit given as "-1" this will always fail
unless we add the appropriate fallback logic here.

In the SetPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, modify the value, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the register. Fix this by masking these bits off before the write.
This is logically the same change as 6d5f89c "USB: EHCI: remove
PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE", but applied to the
Tegra driver rather than the USB core.

So, clear cmd->err at the beginning of a transfer only to handle these
