2012-05-31drm/i915/crt: Do not rely upon the HPD presence pinChris Wilson
Whilst most monitors do wire up the HPD presence pin, it seems quite a few KVM do not. Therefore if we simply rely on the HPD pin being asserted to indicate a connected monitor we fail miserable, so fall back to performing a DCC query for the EDID.

2012-05-31hwrng: atmel-rng - fix race condition leading to repeated bitsPeter Korsgaard
Data valid gets cleared by reading the ISR (status register) and NOT from reading ODATA (data register). A new data word can become available between checking ISR and reading ODATA, causing us to reuse the same data word next time atmel_trng_read() gets called, if that happens before the following data word is ready. With this fixed, rngtest no longer complains of 'Continous run' errors.

2012-05-31md: raid1/raid10: fix problem with merge_bvec_fnNeilBrown
The new merge_bvec_fn which calls the corresponding function in subsidiary devices requires that mddev->merge_check_needed be set if any child has a merge_bvec_fn. However were were only setting that when a device was hot-added, not when a device was present from the start. This bug was introduced in 3.4 so patch is suitable for 3.4.y kernels. However that are conflicts in raid10.c so a separate patch will be needed for 3.4.y.

We weren't copying the id field so when we sent the response back to the frontend (especially with a 64-bit host and 32-bit guest), we ended up using a random value. This lead to the frontend crashing as it would try to pass to __blk_end_request_all a NULL 'struct request' (b/c it would use the 'id' to find the proper 'struct request' in its shadow array) and end up crashing: BUG: unable to handle kernel NULL pointer dereference at 000000e4 IP: [<c0646d4c>] __blk_end_request_all+0xc/0x40 .. snip..

2012-05-30virtio-net: remove useless disable on freezeMichael S. Tsirkin
disable_cb is just an optimization: it can not guarantee that there are no callbacks. In particular it doesn't have any effect when event index is on. Instead, detach, napi disable and reset on freeze ensure we don't run concurrently with a callback. Remove the useless calls so we get same behaviour with and without event index.

2012-05-30[SCSI] fix scsi_wait_scanJames Bottomley
Commit c751085943362143f84346d274e0011419c84202 Author: Rafael J. Wysocki <rjw@sisk.pl> Date: Sun Apr 12 20:06:56 2009 +0200 PM/Hibernate: Wait for SCSI devices scan to complete during resume Broke the scsi_wait_scan module in 2.6.30. Apparently debian still uses it so fix it and backport to stable before removing it in 3.6. The breakage is caused because the function template in include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in. That means that in the modular case (which is every distro), the scsi_wait_scan module does a simple async_synchronize_full() instead of waiting for scans.

This patch should go into 3.5 fixes. The bug was added in the patches for the 3.5 feature window. As you can see from the patch I made a mistake. During development I switched from passing a struct to the size of the struct, but left the sizeof.

Also strengthen the disrecommendation of the protocol mangling while we're at it. In the case of regmap-i2c we remove the requirement for mangling as I2C_M_NOSTART is the only mangling feature which is being used.

2012-05-30i2c-dev: Add support for I2C_M_RECV_LENJean Delvare
As the bus driver side implementation of I2C_M_RECV_LEN is heavily tied to SMBus, we can't support received length over 32 bytes, but let's at least support that. In practice, the caller will have to setup a buffer large enough to cover the case where received length byte has value 32, so minimum 32 + 1 = 33 bytes, possibly more if there is a fixed number of bytes added for the specific slave (for example a checksum.)
