2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell4-11/+11
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>
2012-01-13mmc: fix a deadlock between system suspend and MMC block IOGuennadi Liakhovetski1-3/+6
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.

Host may now use MMC_CAP2_NO_SLEEP_CMD to disable the use of eMMC sleep/awake command. This option can be used when your platform has a buggy kernel crash dump software, which is supposed to store the dump on the eMMC, but is not able to wake up the eMMC from sleep state. In particular, failures have been seen with u-boot; even if it is fixed there, platforms will be slow to update their bootloader binaries.
