| | | | | | | | | | | | | | | | | | | | | | cpu_is_xxx() macros are identifying generic at91sam9g45 chip. This patch adds the capacity to differentiate Engineering Samples and final lots through the inclusion of at91_cpu_fully_identify() and the related chip IDs with chip version field preserved.

| * avr32: add two new at91 to cpu.h definitionNicolas Ferre2009-11-031-0/+2
| | | | | | | | | | | | | | | | | | Somme common drivers will need those at91 cpu_is_xxx() definitions. As at91sam9g10 and at91sam9g45 are on the way to linus' tree, here is the patch that adds those chips to cpu.h in AVR32 architecture.

| * MIPS: Alchemy: Fix hang with high-frequency edge interruptsManuel Lauss2009-11-021-8/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handle_edge_irq() flowhandler disables edge int sources which occur too fast (i.e. another edge comes in before the irq handler function had a chance to finish). Currently, the mask_ack() callback does not ack the edges in hardware, leading to an endless loop in the flowhandler where it tries to shut up the irq source. When I rewrote the alchemy IRQ code I wrongly assumed the mask_ack() callback was only used by the level flowhandler, hence it omitted the (at the time pointless) edge acks. Turned out I was wrong; so here is a complete mask_ack implementation for Alchemy IC, which fixes the above mentioned problem.

| * MIPS: Fix machine check exception in kmap_coherent()Kevin Cernekee2009-11-022-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an SMP system with cache aliases, the following sequence of events may happen: 1) copy_user_highpage() runs on CPU0, invoking kmap_coherent() to create a temporary mapping in the fixmap region 2) copy_page() starts on CPU0 3) CPU1 sends CPU0 an IPI asking CPU0 to run local_r4k_flush_cache_page() 4) CPU0 takes the interrupt, interrupting copy_page() 5) local_r4k_flush_cache_page() on CPU0 calls kmap_coherent() again 6) The second invocation of kmap_coherent() on CPU0 tries to use the same fixmap virtual address that was being used by copy_user_highpage() 7) CPU0 throws a machine check exception for the TLB address conflict Fixed by creating an extra set of fixmap entries for use in interrupt handlers. This prevents fixmap VA conflicts between copy_user_highpage() running in user context, and local_r4k_flush_cache_page() invoked from an SMP IPI.
