Unify the naming method between kernel and the user-space oprofile tool. Because loongson is used instead of godson in most of the places, we agreed to use loongson instead, which will simplify future maintenance. Signed-off-by:

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. Signed-off-by:

TXx9 SPI bit rate is calculated by: fBR = fSPI / 2 / (n + 1) (fSPI is SPI master clock freq, i.e. imbusclk freq.) So use imbus_clk / 2 as a spi-baseclk. Signed-off-by:

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. Signed-off-by:

We've silently been relying on the hardware chopping off excess, reserved ASID bits for no better reason that it saving an instruction. Because we already have: #define cpu_asid(cpu, mm) (cpu_context((cpu), (mm)) & ASID_MASK) in <asm/mmu_context.h>. We can use a cleanup to avoid writing non-zero bits into the reserved entryhi bits. This avoid triggering some debugging assertion in the Cavium simulator. Signed-off-by:
