bridge: Adjust min age inc for HZ > 256

min age increment needs to round up its min age tick for all
HZ values to guarantee message age is increasing.

bridge: message age needs to increase, not decrease.

commit bridge: send proper message_age in config BPDU
added this gem:
  bpdu.message_age = (jiffies - root->designated_age)
  p->designated_age = jiffies + bpdu->message_age;
Notice how bpdu->message_age is negated when reassigned to
bpdu.message_age. This causes message age to decrease breaking the
STP protocol.

HID: hid-input: allow array fields out of range

Allow array field values out of range as per HID 1.11 specification,
section 6.2.25:

	Rather than returning a single bit for each button in the group, an
	array returns an index in each field that corresponds to the pressed
	button (like keyboard scan codes). An out-of range value in and array
	field is considered no controls asserted.

Apparently, "and" above is a typo and should be "an".

This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never
released.

The relevant part of Waltop tablet report descriptors is this:

	0x09, 0x42,         /*          Usage (Tip Switch),         */
	0x09, 0x44,         /*          Usage (Barrel Switch),      */
	0x09, 0x46,         /*          Usage (Tablet Pick),        */
	0x15, 0x01,         /*          Logical Minimum (1),        */
	0x25, 0x03,         /*          Logical Maximum (3),        */
	0x75, 0x04,         /*          Report Size (4),            */
	0x95, 0x01,         /*          Report Count (1),           */
	0x80,               /*          Input,                      */

In 'ql_adapter_initialize'

which is as good as 'spin_unlock_irq()' (unconditional interrupt
enabling). If this is intended, then for better performance
'spin_unlock_irqrestore()' can be replaced with 'spin_unlock_irq()'
and 'spin_lock_irqsave()' can be replaced by 'spin_lock_irq()

flush_tlb_range() needs ->page_table_lock when ->mmap_sem is not held

All other callers already hold either ->mmap_sem (exclusive) or
->page_table_lock.  And we need it because some page table flushing
instanced do work explicitly with ge tables.

See e.g.  arch/powerpc/mm/tlb_hash32.c, flush_tlb_range() and
flush_range() in there.  The same goes for uml, with a lot more
extensive playing with page tables.

Almost all callers are actually fine - flush_tlb_range() may have no
need to bother playing with page tables, but it can do so safely; again,
this caller is the sole exception - everything else either has exclusive
->mmap_sem on the mm in question, or mm->page_table_lock is held.

1) TCP SACK processing can calculate an incorrect reordering value in

2) tcp_mark_head_lost() can split SKBs in situations where it should

6) We must check the return value of nlmsg_parse() before trying to use
   the results.  From Eric Dumazet.

7) Bridging code fails to check return value of ipv6_dev_get_saddr()
   thus potentially leaving uninitialized garbage in the outgoing ipv6
   header.  From Ulrich Weber.

8) Due to rounding and a reversed operation on jiffies, bridge message
   ages can go backwards instead of forwards, thus breaking STP.  Fixes
   from Joakim Tjernlund.

9) r8169 modifies Config* registers without properly holding the
   Config9346 lock, resulting in corrupted IP fragments on some chips.
   Fix from Francois Romieu.

10) NET_PACKET_ENGINE default wan't set properly during the network
