kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05Z

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. 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.

ide: clean up timed out request handling

2010-10-26T17:17:30Z

8f6205cd572fece673da0255d74843680f67f879 introduced a bug where a timed out DMA request is never requeued and lost. 6072f7491f5ef391a575e18a1165e72a3eef1601 fixed this by making ide_dma_timeout_retry() requeue the request itself. While the fix is correct, it makes DMA and non-DMA paths asymmetric regarding how the in flight request is requeued. As long as hwif->rq is set, the IDE driver is assuming ownership of the request and the request should either be completed or requeued when clearing hwif->rq. In the timeout path, the ide driver holds onto the request as long as the recovery action (ie. reset) is in progress and clears it after the state machine is stopped (ide_stopped return), so the existing requeueing logic is correct. The bug occurred because ide_dma_timeout_retry() explicitly clears hwif->rq without requeueing it. ide_dma_timeout_retry() is called only by ide_timer_expiry() and returns ide_started only when ide_error() would return it - ie. after reset state machine has started in which case the state machine will eventually end up executing the ide_stopped path in ide_timer_expiry() after reset protocol is complete. So, there is no need to clear hwif->rq from ide_dma_timeout_retry(). ide_timer_expiry() will handle it the same way as PIO timeout path. Kill hwif->rq clearing and requeueing from ide_dma_timeout_retry() and let ide_timer_expiry() deal with it. The end result should remain the same. grepping shows ide_dma_timeout_retry() is the only site which clears hwif->rq without taking care of the request, so there shouldn't be similar fallouts.
