2012-02-13pata/at91: use newly introduced SMC accessorsJean-Christophe PLAGNIOL-VILLARD
pata_at91 driver is broken since faee0cc: "make smc register base soc independent" Fix it with newly introduced SMC accessors. The overall action of removal of at91_sys_read/write will allow to use the pata_at91 on a single zImage kernel.

2012-02-13Merge branch 'fix/acer-alc889-fix' into fix/hdaTakashi Iwai
Conflicts: sound/pci/hda/patch_realtek.c Merged back the fix for Acer Aspire 6935 with ALC889 codec. The fix commit was based on 3.2 kernel so that it can be applied to stable kernel cleanly.
2012-02-13ALSA: hda - Fix silent speaker output on Acer Aspire 6935Takashi Iwai
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for the speaker for a standard laptop setup like a HP, a speaker, a mic-in and a line-in. However, on Acer Aspire 6935, it seems that the speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it results in silence by some reason, although the codec itself allows the routing to DAC3/4. As a workaround, the connection list of each pin is reduced to be mapped to either only DAC1/2 or DAC3/4, so that the compatible assignment as in kernel 3.1 is achieved.

2012-02-13ALSA: hda - Fix initialization of secondary capture source on VT1705Takashi Iwai
VT1705 codec has two ADCs where the secondary ADC has no MUX but only a fixed connection to the mic pin. This confused the driver and it tries always overriding the input-source selection by assumption of the existing MUX for the secondary ADC, resulted in resetting the input-source at each time PM (including power-saving) occurs. The fix is simply to check the existence of MUX for secondary ADCs in the initialization code.

2012-02-13drm/modes: do not enforce an odd vtotal for interlaced modesDaniel Vetter
CEA actually specifies an interlaced mode with even vtotal and supplies a diagram showing how this is supposed to work. Note that interlaced modes with an even vtotal seem to be a fairly recent invention. All modelines lore I could dig up with googling says that vtotal for interlaced modes _needs_ to be odd. But the even modelines in CEA are not a spec-bug, there's a figure in CEA-861-E called "Figure 5 Special Interlaced Video Format Timing (Even Vtotal)" that explains how it's supposed to work. Furthermore intel Bspec explicitly mentions that both odd and even interlaced vtotal are supported (VTOTAL register in the south display engine of PCH split chips).

2012-02-13ARM: omap: resolve nebulous 'Error setting wl12xx data'Russell King
It's useful to print the error code when a called function fails so a diagnosis of why it failed is possible. In this case, it fails because we try to register some data for the wl12xx driver, but as the driver is not configured, a stub function is used which simply returns -ENOSYS. Let's do the simple thing for -rc and print the error code. Also, the return code from platform_register_device() at each of these sites was not being checked. Add some checking, and again print the error code. This should be fixed properly for the next merge window so we don't issue error messages merely because a driver is not configured.

Found by review. omap4_sdp4430_wifi_mux_init() is called by an __init marked function, and only calls omap_mux_init_gpio() and omap_mux_init_signal() which are both also an __init marked functions. The only reason this doesn't issue a warning is because the compiler inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init(). So, lets add the __init annotation to ensure this remains safe should the compiler choose not to inline.

2012-02-13drm/i915: enable forcewake voodoo also for gen6Daniel Vetter
We still have reports of missed irqs even on Sandybridge with the HWSTAM workaround in place. Testing by the bug reporter gets rid of them with the forcewake voodoo and no HWSTAM writes. Because I've slightly botched the rebasing I've left out the ACTHD readback which is also required to get IVB working. Seems to still work on the tester's machine, so I think we should go with the more minmal approach on SNB. Especially since I've only found weak evidence for holding forcewake while waiting for an interrupt to arrive, but none for the ACTHD readback.

2012-02-13drm/i915: fixup seqno allocation logic for lazy_requestDaniel Vetter
Currently we reserve seqnos only when we emit the request to the ring (by bumping dev_priv->next_seqno), but start using it much earlier for ring->oustanding_lazy_request. When 2 threads compete for the gpu and run on two different rings (e.g. ddx on blitter vs. compositor) hilarity ensued, especially when we get constantly interrupted while reserving buffers. Breakage seems to have been introduced in commit 6f392d548658a17600da7faaf8a5df25ee5f01f6 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Aug 7 11:01:22 2010 +0100 drm/i915: Use a common seqno for all rings. This patch fixes up the seqno reservation logic by moving it into i915_gem_next_request_seqno. The ring->add_request functions now superflously still return the new seqno through a pointer, that will be refactored in the next patch. Note that with this change we now unconditionally allocate a seqno, even when ->add_request might fail because the rings are full and the gpu died. But this does not open up a new can of worms because we can already leave behind an outstanding_request_seqno if e.g. the caller gets interrupted with a signal while stalling for the gpu in the eviciton paths. And with the bugfix we only ever have one seqno allocated per ring (and only that ring), so there are no ordering issues with multiple outstanding seqnos on the same ring. v2: Keep i915_gem_get_seqno (but move it to i915_gem.c) to make it clear that we only have one seqno counter for all rings. Suggested by Chris Wilson. v3: As suggested by Chris Wilson use i915_gem_next_request_seqno instead of ring->oustanding_lazy_request to make the follow-up refactoring more clearly correct. Also improve the commit message with issues discussed on irc.

2012-02-13tcp: fix range tcp_shifted_skb() passes to tcp_sacktag_one()Neal Cardwell
Fix the newly-SACKed range to be the range of newly-shifted bytes. Previously - since 832d11c5cd076abc0aa1eaf7be96c81d1a59ce41 - tcp_shifted_skb() incorrectly called tcp_sacktag_one() with the start and end sequence numbers of the skb it passes in set to the range just beyond the range that is newly-SACKed. This commit also removes a special-case adjustment to lost_cnt_hint in tcp_shifted_skb() since the pre-existing adjustment of lost_cnt_hint in tcp_sacktag_one() now properly handles this things now that the correct start sequence number is passed in.

2012-02-13tcp: allow tcp_sacktag_one() to tag ranges not aligned with skbsNeal Cardwell
This commit allows callers of tcp_sacktag_one() to pass in sequence ranges that do not align with skb boundaries, as tcp_shifted_skb() needs to do in an upcoming fix in this patch series. In fact, now tcp_sacktag_one() does not need to depend on an input skb at all, which makes its semantics and dependencies more clear.

When eSDHC module is enabled on P5020/P3041/P2041/P1010 with eSDHC version 2.3, there is following errors: mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. It is because eSDHC controller has different bit setting for PROCTL register at 0x28 comparing SD specification. This patch sets DMAS bits correctly for byte operation and does not change the default value of other field of PROCTL register. For other FSL chips, such as MPC8536/P2020, PROCTL[DMAS] bits are reserved and even if they are set to wrong bits, it will not take effective.
