When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

Also, manually reordered the tuner entries.

At some point the Flexcop driver was changed to support newer Flexcop cards.
These modifications however broke the detection of Cablestar 2 DVB-C cards.

The reason is that the earlier version of the driver used to retry
unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297)
seems to be very dependent on these retries and adding them back fixes
Cablestar detection.

This patch restores this behaviour for the CableStar2.

A user noticed that there would continue to be 4-6 keypresses even after the

result in a backlog.

Make the query interval faster, and increase the number of cycles before we

  powerpc/fsl-booke: Fix problem with _tlbil_va being interrupted

VMI initialiation can relocate the fixmap, causing early_ioremap to
malfunction if it is initialized before the relocation.  To fix this,
VMI activation is split into two phases; the detection, which must
happen before setting up ioremap, and the activation, which must happen
after parsing early boot parameters.

This fixes a crash on boot when VMI is enabled under VMware.

An example calling sequence which we did see:

copy_user_highpage -> kmap_atomic -> flush_tlb_page -> _tlbil_va

We got interrupted after setting up the MAS registers before the
tlbwe and the interrupt handler that caused the interrupt also did
a kmap_atomic (ide code) and thus on returning from the interrupt
the MAS registers no longer contained the proper values.

Since we dont save/restore MAS registers for normal interrupts we
need to disable interrupts in _tlbil_va to ensure atomicity.

For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font.  This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.

At the moment it affects all chars for which no substitution character
is defined.  In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g.  control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.

I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e.  chars < 128.

The patch limits the mapping as it probably was meant anyway.

There is a major bug in the cp437 to unicode translation table.  Char
0x7c is mapped to U+00a5 which is the Yen sign and wrong.  The right
mapping is U+00a6 (broken bar).

Furthermore, a mapping for U+00b4 (a widely used character) is missing
even though easily possible.

The patch fixes these, as well as it provides a few other useful
mappings.

The changes are as follows:

  0x0f (enhancement) enables a sort of currency symbol
  0x27 (bug) enables a sort of acute accent which is a widely used character
  0x44 (enhancement) enables a sort of icelandic capital letter eth
  0x7c (major bug) corrects mapping
  0xeb (enhancement) enables a sort of icelandic small letter eth
  0xee (enhancement) enables a sort of math 'element of'

  sched: CPU remove deadlock fix

Lee Schermerhorn noticed yesterday that I broke the mapping_writably_mapped
test in 2.6.7!  Bad bad bug, good good find.

The i_mmap_writable count must be incremented for VM_SHARED (just as
i_writecount is for VM_DENYWRITE, but while holding the i_mmap_lock)
when dup_mmap() copies the vma for fork: it has its own more optimal
version of __vma_link_file(), and I missed this out.  So the count
was later going down to 0 (dangerous) when one end unmapped, then
wrapping negative (inefficient) when the other end unmapped.

The only impact on x86 would have been that setting a mandatory lock on
a file which has at some time been opened O_RDWR and mapped MAP_SHARED
(but not necessarily PROT_WRITE) across a fork, might fail with -EAGAIN
when it should succeed, or succeed when it should fail.

But those architectures which rely on flush_dcache_page() to flush
userspace modifications back into the page before the kernel reads it,
may in some cases have skipped the flush after such a fork - though any
repetitive test will soon wrap the count negative, in which case it will
flush_dcache_page() unnecessarily.

Fix would be a two-liner, but mapping variable added, and comment moved.

Discard low-prioriy Tx interrupts when closing an MN10300 on-chip serial port.

The MN10300 on-chip serial port uses three interrupts to manage its serial
ports:

 (1) A very high priority interrupt that drives virtual DMA for Rx.

 (2) A very high priority interrupt that drives virtual DMA for Tx.

 (3) A normal priority virtual interrupt that does the normal UART interrupt
     stuff and is shared between Rx and Tx.

mn10300_serial_stop_tx() only disables the high priority Tx interrupt.  It
doesn't also disable the normal priority one because it is shared with Rx.

However, the high priority interrupt may interrupt local_irq_disabled()
sections, and so may have queued up a low priority virtual interrupt whilst the
UART driver is asking for the Tx interrupt to be disabled.

The result of this can be an oops when we try to process the interrupt in
mn10300_serial_transmit_interrupt() as port->uart.info and port->uart.info->tty
may have gone away.

To deal with this, if either of those pointers is NULL, we make sure the
high-priority Tx interrupt is disabled and discard the interrupt.  The low
priority interrupt is disabled by the mn10300_serial_pic irq_chip table.
