2012-05-16m68k: Setup CROSS_COMPILE at the topGeert Uytterhoeven
CROSS_COMPILE must be setup before using e.g. cc-option (and a few other as-*, cc-*, ld-* macros), else they will check against the wrong compiler when cross-compiling, and may invoke the cross compiler with wrong or suboptimal compiler options.

2012-05-16ARM: imx6q: prepare and enable init on clks directly instead of clk_get firstRichard Zhao
This also removes the usboh3 clk from the initially turned on clocks which leaked in from an internal development tree. Signed-off-by: Richard Zhao <richard.zhao@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2012-05-16ARM i.MX: remove now unnecessary argument from mxc_timer_initSascha Hauer
As the timer code now does a clk_get to get its clock we don't need the struct clk argument anymore. This also changes the alternative EPIT timer to do a clk_get. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2012-05-16ARM: i.MX: change timer clock from ipg to perclkRichard Zhao
Contrary to the ipg clock the perclk rate is not changed or gated in low power mode, so we choose perclk for gpt. With the port to the common clock framework as a side effect the timer used the rate returned from the peripheral clock but the hardware was still programmed to use the ipg clock, so this patch only changes the hardware to really use the clock it already assumed.

2012-05-16ARM i.MX5: fix gpt peripheral clock pathSascha Hauer
- The gpt peripheral clk parent is per_root, not ipg - The register for selectin per_lp_apm and per_root is MXC_CCM_CBCMR, not MXC_CCM_CBCDR Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2012-05-16[PARISC] fix PA1.1 oops on bootJames Bottomley
All PA1.1 systems have been oopsing on boot since commit f311847c2fcebd81912e2f0caf8a461dec28db41 Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Wed Dec 22 10:22:11 2010 -0600 parisc: flush pages through tmpalias space because a PA2.0 instruction was accidentally introduced into the PA1.1 TLB insertion interruption path when it was consolidated with the do_alias macro.
