2009-12-02drm/radeon/kms: deal with connectors sourced to the same encoderAlex Deucher
Some systems have multiple connectors connected to the same encoder; e.g., DVI and HDMI connected to the same encoder with the same ddc line. Since we expose connectors as xrandr outputs, randr treats them separately which results in it trying to source the same encoder to different crtcs. If we have an HDMI and DVI-D port on the same encoder, pick the one to be considered connected based on the edid (HDMI if edid indicates HDMI, DVI otherwise).

2009-12-02drm/radeon/kms: rework scaler handlingAlex Deucher
Keep requested scaler type in radeon_encoder and the actual scaler type used in radeon_crtc. This prevents us from enabling the scaler when it's not required (i.e., the requested mode is the native mode). Also, always set the adjusted mode equal to the native mode for lvds.

2009-12-01rtc-x1205: reset clock to sane state after power failureJohannes Weiner
When detecting power failure, the probe function would reset the clock time to defined state. However, the clock's _date_ might still be bogus and a subsequent probe fails when sanity-checking these values. Change the power-failure fixup code to do a full setting of rtc_time, including a valid date.

2009-12-01rtc-x1205: fix rtc_time to y2k register value conversionJohannes Weiner
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.

2009-12-01drm/i915: Fix sync to vblank when VGA output is turned offLi Peng
In current vblank-wait implementation, if we turn off VGA output, drm_wait_vblank will still wait on the disabled pipe until timeout, because vblank on the pipe is assumed be enabled. This would cause slow system response on some system such as moblin. This patch resolve the issue by adding a drm helper function drm_vblank_off which explicitly clear vblank_enabled[crtc], wake up any waiting queue and save last vblank counter before turning off crtc. It also slightly change drm_vblank_get to ensure that we will will return immediately if trying to wait on a disabled pipe.

2009-12-01MIPS: Loongson: Switch from flatmem to sparsememWu Zhangjin
With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. The config help of sparsemem says: "This option provides some potential performance benefits, along with decreased code complexity." So to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.

2009-12-01MIPS: Loongson: Disallow 4kB pagesWu Zhangjin
Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.

2009-12-01md: revert incorrect fix for read error handling in raid1.NeilBrown
commit 4706b349f was a forward port of a fix that was needed for SLES10. But in fact it is not needed in mainline because the earlier commit dd00a99e7a fixes the same problem in a better way. Further, this commit introduces a bug in the way it interacts with the automatic read-error-correction. If, after a read error is successfully corrected, the same disk is chosen to re-read - the re-read won't be attempted but an error will be returned instead. After reverting that commit, there is the possibility that a read error on a read-only array (where read errors cannot be corrected as that requires a write) will repeatedly read the same device and continue to get an error. So in the "Array is readonly" case, fail the drive immediately on a read error. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org

The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b "remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect setting of the unaligned access control flags by the prctl syscall. The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]" further caused problems, namely incorrect operands to assembler code as evidenced by: AS arch/alpha/kernel/entry.o arch/alpha/kernel/entry.S: Assembler messages: arch/alpha/kernel/entry.S:326: Warning: operand out of range (0x0000000000000406 is not between 0x0000000000000000 and 0x00000000000000ff) Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be in lower 8 bits of the thread info flags, and (2) making sure that ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.
