Jerome Glisse 4c78867912 drm/radeon/kms: Rework radeon object handling
The locking & protection of radeon object was somewhat messy.
This patch completely rework it to now use ttm reserve as a
protection for the radeon object structure member. It also
shrink down the various radeon object structure by removing
field which were redondant with the ttm information. Last it
converts few simple functions to inline which should with
performances.

Dave Airlie 1614f8b17b drm/radeon/kms: add irq mitigation code for sw interrupt.
We really don't need to process every irq that comes in, we only
really want to do SW irq processing when we are actually waiting for
a fence to pass. I'm not 100% sure this is race free esp on non-MSI systems
so it needs some testing.

Alex Deucher d8f60cfc93 drm/radeon/kms: Add support for interrupts on r6xx/r7xx chips (v3)
This enables the use of interrupts on r6xx/r7xx hardware.
Interrupts are implemented via a ring buffer.  The GPU adds
interrupts vectors to the ring and the host reads them off
in the interrupt handler.  The interrupt controller requires
firmware like the CP.  This firmware must be installed and
accessble to the firmware loader for interrupts to function.

MSIs don't seem to work on my RS780.  They work fine on all
my discrete cards.  I'm not sure about other RS780s or
RS880s.  I've disabled MSIs on RS780 and RS880, but it would
probably be worth checking on some other systems.

v2 - fix some checkpatch.pl problems;
     re-read the disp int status reg if we restart the ih;

v3 - remove the irq handler if r600_irq_init() fails;
     remove spinlock in r600_ih_ring_fini();
     move ih rb overflow check to r600_get_ih_wptr();
     move irq ack to separate function;

However, the clock's _date_ might still be bogus and a subsequent probe

Johannes Weiner 48a7f77468 rtc-x1205: fix rtc_time to y2k register value conversion
The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.

The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.

A subsequent probing of the clock fails due to the invalid value range in
the register, though.

[ And if it didn't, reading the clock would yield a bogus year because
  the function translating registers to tm_year is assuming a register
  value of 19 or 20. ]

This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.
