2012-01-12phylib: introduce mdiobus_alloc_size()Timur Tabi
Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc(). Most callers of mdiobus_alloc() also allocate a private data structure, and then manually point bus->priv to this object. mdiobus_alloc_size() combines the two operations into one, which simplifies memory management. The original mdiobus_alloc() now just calls mdiobus_alloc_size(0). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-01-13module_param: avoid bool abuse, add bint for special cases.Rusty Russell
For historical reasons, we allow module_param(bool) to take an int (or an unsigned int). That's going away. A few drivers really want an int: they set it to -1 and a parameter will set it to 0 or 1. This sucks: reading them from sysfs will give 'Y' for both -1 and 1, but if we change it to an int, then the users might be broken (if they did "param" instead of "param=1"). Use a new 'bint' parser for them. (ntfs has a different problem: it needs an int for debug_msgs because it's also exposed via sysctl.)

2012-01-12brcmsmac: fix reading of PCI sprom contentsLinus Torvalds
It appears that you can only read the sprom contents with aligned 16-bit reads: anything else causes at least some versions of the broadcom chipset to abort the PCI transaction, returning 0xff. This apparently doesn't trigger very often, because most setups don't use an external srom chip, and the OTP sprom loading doesn't have this issue. But at least the current 11" Macbook Air does trigger it, and wireless communications were broken as a result.

2012-01-12mmc: fix a deadlock between system suspend and MMC block IOGuennadi Liakhovetski
Performing MMC block IO with simultaneous STR can lead to a deadlock: the mmc_pm_notify() function claims the host and then calls bus .remove() method, which lands in mmc_blk_remove(), which calls mmc_blk_remove_req() then it goes to -> mmc_cleanup_queue() -> kthread_stop(), which waits for the mmc-block thread to stop. If the mmc-block thread at that time is processing block requests, it will also try to claim the host in mmc_blk_issue_rq() and block there. This patch fixes the problem by calling .remove() before claiming the host.

2012-01-12virtio: balloon: Add freeze, restore handlers to support S4Amit Shah
Handling balloon hibernate / restore is tricky. If the balloon was inflated before going into the hibernation state, upon resume, the host will not have any memory of that. Any pages that were passed on to the host earlier would most likely be invalid, and the host will have to re-balloon to the previous value to get in the pre-hibernate state. So the only sane thing for the guest to do here is to discard all the pages that were put in the balloon. When to discard the pages is the next question. One solution is to deflate the balloon just before writing the image to the disk (in the freeze() PM callback). However, asking for pages from the host just to discard them immediately after seems wasteful of resources. Hence, it makes sense to do this by just fudging our counters soon after wakeup. This means we don't deflate the balloon before sleep, and also don't put unnecessary pressure on the host. This also helps in the thaw case: if the freeze fails for whatever reason, the balloon should continue to remain in the inflated state. This was tested by issuing 'swapoff -a' and trying to go into the S4 state. That fails, and the balloon stays inflated, as expected. Both the host and the guest are happy. Finally, in the restore() callback, we empty the list of pages that were previously given off to the host, add the appropriate number of pages to the totalram_pages counter, reset the num_pages counter to 0, and all is fine. As a last step, delete the vqs on the freeze callback to prepare for hibernation, and re-create them in the restore and thaw callbacks to resume normal operation. The kthread doesn't race with any operations here, since it's frozen before the freeze() call and is thawed after the thaw() and restore() callbacks, so we're safe with that.

2012-01-12virtio: net: Add freeze, restore handlers to support S4Amit Shah
Remove all the vqs, disable napi and detach from the netdev on hibernation. Re-create vqs after restoring from a hibernated image, re-enable napi and re-attach the netdev. This keeps networking working across hibernation. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-01-12virtio: console: Disable callbacks for virtqueues at start of S4 freezeAmit Shah
To ensure we don't receive any more interrupts from the host after we enter the freeze function, disable all vq interrupts. There wasn't any problem seen due to this in tests, but applying this patch makes the freeze case more robust.

2012-01-12virtio: console: Add freeze and restore handlers to support S4Amit Shah
Remove all vqs and associated buffers in the freeze callback which prepares us to go into hibernation state. On restore, re-create all the vqs and populate the input vqs with buffers to get to the pre-hibernate state. Note: Any outstanding unconsumed buffers are discarded; which means there's a possibility of data loss in case the host or the guest didn't consume any data already present in the vqs. This can be addressed in a later patch series, perhaps in virtio common code. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
