2010-02-02crypto: padlock-sha - Add import/export supportHerbert Xu
As the padlock driver for SHA uses a software fallback to perform partial hashing, it must implement custom import/export functions. Otherwise hmac which depends on import/export for prehashing will not work with padlock-sha.

2010-02-02random: drop weird m_time/a_time manipulationMatt Mackall
No other driver does anything remotely like this that I know of except for the tty drivers, and I can't see any reason for random/urandom to do it. In fact, it's a (trivial, harmless) timing information leak. And obviously, it generates power- and flash-cycle wasting I/O, especially if combined with something like hwrngd. Also, it breaks ubifs's expectations. Signed-off-by: Matt Mackall <mpm@selenic.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2010-02-01drm/kms/radeon: pick digitial encoders smarter. (v3)Dave Airlie
booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had on our list, to pick a correct digital encoder block. The LVTMA encoder requires the second digital encoder, all others can use any encoder at all. This fixes the digital encoder selection logic to enable LVDS/DP combos to work okay. V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder. V3: rename to dig_encoder and clean up further - also fix the picking algorithm. tested on Lenovo W500 + desktop 3650 cards. Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-01-31x86/agp: Fix agp_amd64_init regressionFUJITA Tomonori
This fixes the regression introduced by commit 42590a75019a50012f25a962246498dead428433 ("x86/agp: Fix agp_amd64_init and agp_amd64_cleanup"). The above commit changes agp_amd64_init() not to do anything if gart_iommu_aperture is not zero. If GART iommu calls agp_amd64_init(), we need to skip agp_amd64_init() when it's called later via module_init. The problem is that gart_iommu_init() calls agp_amd64_init() with not zero gart_iommu_aperture so agp_amd64_init() is never initialized. When gart_iommu_init() calls agp_amd64_init(), agp should be always initialized.

Commit ac019360fe3 changed the irq handler logic to BUG_ON rather than returning IRQ_NONE when the incoming argument is invalid.

Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down initially for drivers that update link state") changed the initial link state in cdc_ether and other drivers based on the understanding that the devices they support generate link change interrupts. However, this is optional in the CDC Ethernet protocol, and two users have reported in <http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state for their devices remains down.
