This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

Sometimes the dynamic linker would seg-fault at start up and this was eventually traced to the handling of a COW fault for a page which was being modified by the linker. If there was no cache aliasing between the kernel and the user page, the page was not flushed, leaving the newly copied data in the D-cache. However when executing instructions from that page, the I-cache is filled directly from external memory, rather than the D-cache, and causing garbage to be executed.

| | * | | kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-20

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | SH-X3 controllers all have pretty dire delays needed for PHY wakeup, so we attempt to mitigate the damage by bringing them up asynchronously, simply using the synchronization points for persistent bridge to channel numbering.
