V4L/DVB (5777): Dvb-pll digitv dvb-usb: Eliminate last user of dvb_pll_configure
The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure(). It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.
There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().
The other was the digitv driver. This driver can use one of two demods,
mt352 or nxt6000.
For the mt352, the driver would set tuner_ops.calc_regs to
dvb_usb_tuner_calc_regs().
We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by
that module. For the nxt600, the driver would set tuner_ops.set_params
to digitv_nxt6000_tuner_set_params.
That function would in turn use dvb_usb_tuner_calc_regs().
We convert it to use tuner_ops.calc_regs() instead, and use
dvb_pll_attach.
The digitv_tuner_attach() needs to know which frontend was attached by
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params()
to be overridden with digitv_nxt6000_tuner_set_params().
So, to do this a digitv_state that says which frontend was used is added
to the dvb_usb_device private state field.

V4L/DVB (5636): Integrate all users of the fmd1216 tuner with dvb-pll
Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.
The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point. This the recommended value for
DVB-T operation.
The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).
The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.
CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid

CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod
This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence. The non-dvb-pll code for this
user is removed.
X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro
In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:
SAA7134_BOARD_MD7134 Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM
The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.
This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.
For the cxusb driver, only one board is effected:
USB_PID_MEDION_MD95700 Medion MD95700
This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively. These functions are effectively the same
as the dvb-pll versions. They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does). This board will gain
the sleep sequence, while init and tuning should be unchanged.

xen: use iret directly when possible
Most of the time we can simply use the iret instruction to exit the
kernel, rather than having to use the iret hypercall - the only
exception is if we're returning into vm86 mode, or from delivering an
NMI (which we don't support yet).
When running native, iret has the behaviour of testing for a pending
interrupt atomically with re-enabling interrupts. Unfortunately
there's no way to do this with Xen, so there's a window in which we
could get a recursive exception after enabling events but before
actually returning to userspace.
This causes a problem: if the nested interrupt causes one of the
task's TIF_WORK_MASK flags to be set, they will not be checked again
before returning to userspace. This means that pending work may be
left pending indefinitely, until the process enters and leaves the
kernel again. The net effect is that a pending signal or reschedule
event could be delayed for an unbounded amount of time.
To deal with this, the xen event upcall handler checks to see if the
EIP is within the critical section of the iret code, after events
are (potentially) enabled up to the iret itself. If its within this
range, it calls the iret critical section fixup, which adjusts the
stack to deal with any unrestored registers, and then shifts the
stack frame up to replace the previous invocation.

xen: suppress abs symbol warnings for unused reloc pointers
arch/i386/xen/xen-asm.S defines some small pieces of code which are
used to implement a few paravirt_ops. They're designed so they can be
used either in-place, or be inline patched into their callsites if
there's enough space.
Some of those operations need to make calls out (specifically, if you
re-enable events [interrupts], and there's a pending event at that
time). These calls need the call instruction to be relocated if the
code is patched inline. In this case xen_foo_reloc is a
section-relative symbol which points to xen_foo's required relocation.
Other operations have no need of a relocation, and so their
corresponding xen_bar_reloc is absolute 0. These are the cases which
are triggering the warning.
This patch adds those symbols to the list of safe abs symbols.

xen: Place vcpu_info structure into per-cpu memory
An experimental patch for Xen allows guests to place their vcpu_info
structs anywhere. We try to use this to place the vcpu_info into the
PDA, which allows direct access.
If this works, then switch to using direct access operations for
irq_enable, disable, save_fl and restore_fl.

xen: handle external requests for shutdown, reboot and sysrq
The guest domain can be asked to shutdown or reboot itself, or have a
sysrq key injected, via xenbus. This patch adds a watcher for those
events, and does the appropriate action.

xen: Add grant table support
Add Xen 'grant table' driver which allows granting of access to
selected local memory pages by other virtual machines and,
symmetrically, the mapping of remote memory pages which other virtual
machines have granted access to.
This driver is a prerequisite for many of the Xen virtual device
drivers, which grant the 'device driver domain' restricted and
temporary access to only those memory pages that are currently
involved in I/O operations.

xen: hack to prevent bad segment register reload
The hypervisor saves and restores the segment registers as part of the
state is saves while context switching. If, during a context switch,
the next process doesn't use the TLS segments, it invalidates the GDT
entry, causing the segment register reload to fault. This fault
effectively doubles the cost of a context switch.
This patch is a band-aid workaround which clears the usermode %gs
after it has been saved for the previous process, but before it gets
reloaded for the next, and it avoids having the hypervisor attempt to
erroneously reload it.

xen: lazy-mmu operations
This patch uses the lazy-mmu hooks to batch mmu operations where

active pagetables, which happens during mprotect, munmap, mremap and

helped).
