2016-03-17IB/hfi1: Don't call cond_resched in atomic mode when sending packetsKaike Wan1-2/+5
This patch fixed the problem where the driver might reschedule in atomic mode when sending packets. This is due to the fact that the call to cond_resched() in hfi1_do_send() might occur in atomic mode and a check is required to avoid the warning message: "kernel: BUG: scheduling while atomic: swapper/2/0/0x10000100."

2016-03-17IB/hfi1: Add adaptive cacheless verbs copyDean Luick3-2/+211
The kernel memcpy is faster than a cacheless copy. However, if too much of the L3 cache is overwritten by one-time copies then overall bandwidth suffers. Implement an adaptive scheme where full page copies are tracked and if the number of unique entries are larger than a threshold, verbs will use a cacheless copy. Tracked entries are gradually cleaned, allowing memcpy to resume once the larger copies have stopped.

2016-03-17mmc: sdhci: Fix override of timeout clk wrt max_busy_timeoutAdrian Hunter1-3/+3
Normally the timeout clock frequency is read from the capabilities register. It is also possible to set the value prior to calling sdhci_add_host() in which case that value will override the capabilities register value. However that was being done after calculating max_busy_timeout so that max_busy_timeout was being calculated using the wrong value of timeout_clk. Fix that by moving the override before max_busy_timeout is calculated. The result is that the max_busy_timeout and max_discard increase for BSW devices so that, for example, the time for mkfs.ext4 on a 64GB eMMC drops from about 1 minute 40 seconds to about 20 seconds. Note, in the future, the capabilities setting will be tidied up and this override won't be used anymore. However this fix is needed for stable.

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

2016-03-17mmc: tegra: properly disable card clockLucas Stach1-1/+1
The new code to do the clock rate setting externally to the SDMMC module has a shortcut to not propagate changes with a 0 rate to the CAR by simply bailing out. This breaks proper cutting of the card clock. Fix it by directly calling the correct sdhci function.

->export() might be called before we have done an update operation, and in this case the ->state field is left uninitialized. Put the correct default value when initializing the request. Signed-off-by: Boris Brezillon <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
