2010-05-11[ARM] pxa/cm-x300: update the memory fixup.Igor Grinberg
CM-X300 bootloader passes DRAM configuration information in ATAGS, however, the first memory bank is reported at actual physical address 0x8000000. Use the configuration information supplied by the bootloader and cope with the necessity to have PHYS_ADDR=0xa0000000.

2010-05-11[ARM] pxa: correct SSCR0_SCR to support multiple SoCsEric Miao
The previous definitions of SSCR0_SCR and SSCR0_SerClkDiv() prevented them being used simultaneously when supporting multiple PXA SoCs, esp. in drivers/spi/pxa2xx_spi.c, make them correct. The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result a little bit different in pxa2xx_spi_probe(), however, since that's only used as a default initialization value, it's acceptable.

2010-05-09cpuidle: Fix incorrect optimizationArjan van de Ven
commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

2010-05-07md: restore ability of spare drives to spin down.NeilBrown
Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668cb2e3fd1827a55 broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.
