[PATCH] holepunch: fix disconnected pages after second truncate

shmem_truncate_range has its own truncate_inode_pages_range, to free any pages
racily instantiated while it was in progress: a SHMEM_PAGEIN flag is set when
this might have happened.  But holepunching gets no chance to clear that flag
at the start of vmtruncate_range, so it's always set (unless a truncate came
just before), so holepunch almost always does this second
truncate_inode_pages_range.

shmem holepunch has unlikely swap<->file races hereabouts whatever we do
(without a fuller rework than is fit for this release): I was going to skip
the second truncate in the punch_hole case, but Miklos points out that would
make holepunch correctness more vulnerable to swapoff.  So keep the second
truncate, but follow it by an unmap_mapping_range to eliminate the
disconnected pages (freed from pagecache while still mapped in userspace) that
it might have left behind.

Miklos Szeredi observes that during truncation of shmem page directories,
info->lock is released to improve latency (after lowering i_size and
next_index to exclude races); but this is quite wrong for holepunching, which
receives no such protection from i_size or next_index, and is left vulnerable
to races with shmem_unuse, shmem_getpage and shmem_writepage.

Hold info->lock throughout when holepunching?  No, any user could prevent
rescheduling for far too long.  Instead take info->lock just when needed: in
shmem_free_swp when removing the swap entries, and whenever removing a
directory page from the level above.  But so long as we remove before

dev_create()->dm_create()->alloc_dev()-> blk_queue_bounce_limit(md->queue,
BLK_BOUNCE_ANY) is called.

blk_queue_bounce_limit(BLK_BOUNCE_ANY) calls init_emergency_isa_pool() if
blk_max_pfn < blk_max_low_pfn.  This is the case on UML, but
init_emergency_isa_pool() hits BUG_ON(!isa_page_pool) because there doesn't
seem to be a dma zone on UML for mempool_create() to allocate from.

Most architectures seem to have max_low_pfn == max_pfn, but UML doesn't
because of the uml_reserved chunk it keeps for itself.  From what I can see,
max_pfn and max_low_pfn don't get much use after the bootmem-allocator stops

blk_max_low_pfn/blk_max_pfn.

This ensures init_emergency_isa_pool() doesn't crash uml in this situation by

mightymouse doesn't work.  The USB version of mightymouse works, as there
is a quirk for handling scrollwheel in hid/usbhid for it.

Now that bluetooth git tree is hooked to generic hid layer, it could easily
use the quirks which are already present in generic hid parser, hid-input,
etc.

handling to current bluetooth hidp code, and sets quirk flags for device
0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

myri10ge: correctly detect when TSO should be used

Correctly detect when TSO should be used on transmit by looking at the
skb->gso_size rather than seeing if the frame was larger than our MTU.
The old method causes problems when a host with a large (jumbo) MTU is
sending to a host with a small (standard) MTU.

The problem is that we call disable_nonboot_cpus() in swsusp before
powering down the system in order to avoid triggering the WARN_ON()
in arch/x86_64/kernel/acpi/sleep.c:init_low_mapping() and this doesn't
work well on Thomas' system.

So instead, remove the WARN_ON() in arch/x86_64/kernel/acpi/sleep.c:
init_low_mapping(), which triggers every time during the suspend to disk
in the platform mode, as the potential problem it is related to doesn't
seem to occur in practice.

[ I think we might want to disallow the case of multiple users of that

  tables on the current CPU should be fine as long as we don't have

[PATCH] ntp: avoid time_offset overflows

I've been seeing some odd NTP behavior recently on a few boxes and
finally narrowed it down to time_offset overflowing when converted to
SHIFT_UPDATE units (which was a side effect from my HZfreeNTP patch).

This patch converts time_offset from a long to a s64 which resolves the
issue.

[PATCH] uml: use correct register file size everywhere

This patch uses MAX_REG_NR consistently to refer to the register file size.
 FRAME_SIZE isn't sufficient because on x86_64, it is smaller than the
ptrace register file size.  MAX_REG_NR was introduced as a consistent way
to get the number of registers, but wasn't used everywhere it should be.

When this causes a problem, it makes PTRACE_SETREGS fail on x86_64 because
of a corrupted segment register value in the known-good register file.  The
patch also adds a register dump at that point in case there are any future
problems here.
