sfc: Leave interrupts and event queues enabled whenever we can
When SR-IOV is enabled we may receive FLR (Function-Level Reset) events, associated queue flush events and requests from VF drivers at any time. Therefore we need to keep event queues and interrupts enabled whenever possible.
Currently we stop interrupt-driven event processing before flushing RX and TX queues; efx_nic_flush_queues() then polls event queues for flush events and discards any others it finds. Change it to work with the regular event handling functions.
Currently efx_start_channel() fills RX queues synchronously when a device is brought up. This could now race with NAPI, so change it to send fill events.
This was almost entirely written by Steve Hodgson, formerly shodgson@solarflare.com.

The 'page size' for PCIe DMA, i.e. the alignment of boundaries at which DMA must be broken, is 4KB. Name this value as EFX_PAGE_SIZE and use it in efx_max_tx_len(). Redefine EFX_BUF_SIZE as EFX_PAGE_SIZE since its value is also a result of that requirement, and use it in efx_init_special_buffer().

sfc: Clean up test interrupt handling
Interrupts are normally generated by the event queues, moderated by timers. However, they may also be triggered by detection of a 'fatal' error condition (e.g. memory parity error) or by the host writing to certain CSR fields as part of a self-test.
The IRQ level/index used for these on Falcon rev B0 and Siena is set by the KER_INT_LEVE_SEL field and cached by the driver in efx_nic::fatal_irq_level. Since this value is also relevant to self-tests rename the field to just 'irq_level'.
Avoid unnecessary cache traffic by using a per-channel 'last_irq_cpu' field and only writing to the per-controller field when the interrupt matches efx_nic::irq_level. Remove the volatile qualifier and use ACCESS_ONCE in the places we read these fields.

sfc: Consistently test DEBUG macro, not EFX_ENABLE_DEBUG
The netif_dbg() macro is defined in <linux/netdevice.h>. If the DEBUG macro is defined, it logs a message at 'debug' level, otherwise it does nothing.
In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but this is too late for those source files that already got a definition of netif_dbg() by including <linux/netdevice.h>
Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG.
In mtd.c, we do not use DEBUG as a condition flag but are forced to use the DEBUG macro-function from <linux/mtd/mtd.h>. Undefine DEBUG before including it.

In the last one, the interrupt was not properly released on module remove. It was not freed because the flag irqs_hooked was not set during initialization in the case of using legacy IRQ.

sfc: fix calling of free_irq with already free vector If the sfc driver is in legacy interrupt mode (either explicitly by using interrupt_mode module param or by falling back to it) it will hit a warning at kernel/irq/manage.c because it will try to free an irq which wasn't allocated by it in the first place because the MSI(X) irqs are zero and it'll try to free them unconditionally. So fix it by checking if we're in legacy mode and freeing the appropriate irqs.

sfc: Correct RX dropped count for drops while interface is down We don't directly control RX ingress on Siena or any later controllers, and so we cannot prevent packets from entering the RX datapath while the RX queues are not set up. This results in the hardware incrementing RX_NODESC_DROP_CNT, but it's not an error and we should not include it in error stats. When bringing an interface up or down, pull (or wait for) stats and count the number of packets that were dropped while the interface was down. Subtract this from the reported RX dropped count.

Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next Ben Hutchings says: ==================== 1. A little more refactoring. 2. Remove the unnecessary use of atomic_t that you pointed out. 3. Add support for starting or queueing firmware requests from atomic context. 4. Add hwmon support for additional sensors found on some new boards. 5. Add support for the EF10 controller architecture, the SFC9100 family and specifically the SFC9120 controller. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherent __GFP_ZERO is an uncommon flag and perhaps is better not used. static inline dma_zalloc_coherent exists so convert the uses of dma_alloc_coherent with __GFP_ZERO to the more common kernel style with zalloc. Remove memset from the static inline dma_zalloc_coherent and add just one use of __GFP_ZERO instead. Trivially reduces the size of the existing uses of dma_zalloc_coherent. Realign arguments as appropriate.
