David Brownell e6d2bb2bac rtc: make HPET_RTC_IRQ track HPET_EMULATE_RTC
More Kconfig tweaks related to the legacy PC RTC code:

 - Describe the legacy PC RTC driver as such ... it's never quite
   been clear that this driver is for PC RTCs, and now it's fair
   to call this the "legacy" driver.

 - Force it to understand about HPET stealing its IRQs ... kernel
   code does this always when HPET is in use, there should be no
   option for users to goof up the config.

This seems to fix kernel bugzilla #10729.

    unicode diacritics support

because that changeset made k_self consider the value as a latin1
character when in Unicode mode, which is wrong; k_self should still take
the console map into account.

Since many distros load this driver by default (throw it against the wall

David Sterba eb4e545d4a ipwireless: Fix blocked sending
Packet sending is driven by two flags, tx_ready and tx_queued.
It was possible, that there were queued data for sending and
hardware was flagged as blocked but in fact it was not.

The tx_queued was indicator but should be really a counter else
first fragmented packet resets tx_queued flag, but there may be
pending packets which do not get sent.

New semantics:
tx_ready - set, if hw is ready to send packet, no packet is being
           transferred right now
           set the flag right at the place where data are copied
           into hw memory and not earlier without checking if it
           was succesful
tx_queued - count of enqueued packets, including fragments

Rusty Russell f7f510ec19 virtio: An entropy device, as suggested by hpa.
Note that by itself, having a "hardware" random generator does very
little: you should probably run "rngd" in your guest to feed this into
the kernel entropy pool.

Included:
	virtio_rng: dont use vmalloced addresses for virtio

	If virtio_rng is build as a module, random_data is an address
	in vmalloc space. As virtio expects guest real addresses, this
	can cause any kind of funny behaviour, so lets allocate
	random_data dynamically with kmalloc.

David S. Miller 93dae5b70e sparc64: Add global register dumping facility.
When a cpu really is stuck in the kernel, it can be often
impossible to figure out which cpu is stuck where.  The
worst case is when the stuck cpu has interrupts disabled.

Therefore, implement a global cpu state capture that uses
SMP message interrupts which are not disabled by the
normal IRQ enable/disable APIs of the kernel.

As long as we can get a sysrq 'y' to the kernel, we can
get a dump.  Even if the console interrupt cpu is wedged,
we can trigger it from userspace using /proc/sysrq-trigger

The output is made compact so that this facility is more
useful on high cpu count systems, which is where this
facility will likely find itself the most useful :)

Ingo Molnar 487ad7efbf tty: fix BKL related leak and crash
Enabling the BKL to be lockdep tracked uncovered the following
upstream kernel bug in the tty code, which caused a BKL
reference leak:

  ================================================
  [ BUG: lock held when returning to user space! ]
  ------------------------------------------------
  dmesg/3121 is leaving the kernel with locks still held!
  1 lock held by dmesg/3121:
   #0:  (kernel_mutex){--..}, at: [<c02f34d9>] opost+0x24/0x194

this might explain some of the atomicity warnings and crashes
that -tip tree testing has been experiencing since the BKL
was converted back to a spinlock.

For e.g.  proper TTY canonical support, IUTF8 termios flag has to be set as
appropriate.  Linux used to not care about setting that flag for VT TTYs.

This patch fixes that by activating it according to the current mode of the
VT, and sets the default value according to the vt.default_utf8 parameter.

Roman Zippel f8bd2258e2 remove div_long_long_rem
x86 is the only arch right now, which provides an optimized for
div_long_long_rem and it has the downside that one has to be very careful that
the divide doesn't overflow.

The API is a little akward, as the arguments for the unsigned divide are
signed.  The signed version also doesn't handle a negative divisor and
produces worse code on 64bit archs.

There is little incentive to keep this API alive, so this converts the few
users to the new API.
