* | msm: smd: provide atomic channel writesBrian Swetland2010-05-12
| | | | | | | | | | | | | | | | | | | | Some smd clients may write from multiple threads, in which case it's not safe to call smd_write without holding a lock. smd_write_atomic() provides the same functionality as smd_write() but obtains the smd lock first.

* [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
| | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
