ppc: RECLAIM_DISTANCE 10?

2014-02-18 Thread Michal Hocko
Hi, I have just noticed that ppc has RECLAIM_DISTANCE reduced to 10 set by 56608209d34b (powerpc/numa: Set a smaller value for RECLAIM_DISTANCE to enable zone reclaim). The commit message suggests that the zone reclaim is desirable for all NUMA configurations. History has shown that the zone

[PATCH RFC 00/31] SDHCI and SDIO IRQ improvements

2014-02-18 Thread Russell King - ARM Linux
The following patch series is targetted at two things - fixing the SDIO interrupt handling, and fixing problems with the sdhci driver. - the first two patches from Thomas Gleixner provide genirq support to allow us to fix the SDIO interrupt handling in a graceful manner. - patch 3 adds support
