* serial: bfin_5xx: split uart RX lock from uart port lock to avoid deadlockSonic Zhang2011-02-03
| | | | | | | | | | | | | | | | | | | | The RX lock is used to protect the RX buffer from concurrent access in DMA mode between the timer and RX interrupt routines. It is independent from the uart lock which is used to protect the TX buffer. It is possible for a uart TX transfer to be started up from the RX interrupt handler if low latency is enabled. So we need to split the locks to avoid deadlocking in this situation. In PIO mode, the RX lock is not necessary because the handle_simple_irq and handle_level_irq functions ensure driver interrupt handlers are called once on one core. And now that the RX path has its own lock, the TX interrupt has nothing to do with the RX path, so disabling it at the same time.

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

If allowing the netdevice framework to probe both 3 phys of the switch when registering MAC phy, phy at address 1 is checked for link active status other than phy at address 3. If connecting a cable to port 2 and leave port 1 open, link status in phy 2 and 3 are online, while that in phy 1 is offline. So, the phy layer sets wrong offline status to net device on port 3.

* | | Blackfin: SMP: rewrite IPI handling to avoid memory allocationYi Li2011-01-10

But often times, we will want to send an IPI in low level contexts where allocation is not possible which may lead to a panic(). So create a per-cpu static array for the message queue and use that instead. Further, while we have two supplemental interrupts, we are currently only using one of them. So use the second one for the most common IPI message of all -- smp_send_reschedule(). This avoids ugly contention for locks which in turn would require an IPI message ... In general, this improves SMP performance, and in some cases allows the SMP port to work in places it wouldn't before. Such as the PREEMPT_RT state where the slab is protected by a per-cpu spin lock. If the slab kmalloc/kfree were to put the task to sleep, and that task was actually the IPI handler, then the system falls down yet again. After running some various stress tests on the system, the static limit of 5 messages seems to work. On the off chance even this overflows, we simply panic(), and we can review that scenario to see if the limit needs to be increased a bit more.

So having any of the sub-mach headers trying to include asm/blackfin.h makes no sense -- punt it. The mach/blackfin.h header takes care of including the part-specific def headers which in turn will include any other needed def file. Similarly, it takes care of pulling in the part-specific cdef header. So move this logic out of the blackfin.h when necessary. Further, make sure the cdef headers do not waste time including the def headers again. Since all parts need the common def/cdef headers, move this logic out of the part-specific headers and into the mach/blackfin.h file. Finally, we need to split the BF539 def header since the BF538 does not have MXVR and we don't want to expose those MMRs. So now all parts should have the same behavior: mach/blackfin.h asm/def_LPBlackfin.h part-specific def.h if ! asm asm/cdef_LPBlackfin.h part-specific cdef.h And the sub def/cdef headers only tail into what they need.
