2009-03-12[ARM] Fix virtual to physical translation macro corner casesRussell King
The current use of these macros works well when the conversion is entirely linear. In this case, we can be assured that the following holds true: __va(p + s) - s = __va(p) However, this is not always the case, especially when there is a non-linear conversion (eg, when there is a 3.5GB hole in memory.) In this case, if 's' is the size of the region (eg, PAGE_SIZE) and 'p' is the final page, the above is most definitely not true. So, we must ensure that __va() and __pa() are only used with valid kernel direct mapped RAM addresses. This patch tweaks the code to achieve this.

2009-03-12[ARM] 5421/1: ftrace: fix crash due to tracing of __naked functionsUwe Kleine-König
This is a fix for the following crash observed in 2.6.29-rc3: http://lkml.org/lkml/2009/1/29/150 On ARM it doesn't make sense to trace a naked function because then mcount is called without stack and frame pointer being set up and there is no chance to restore the lr register to the value before mcount was called.

2009-03-10linker script: define __per_cpu_load on all SMP capable archsTejun Heo
Impact: __per_cpu_load available on all SMP capable archs Percpu now requires three symbols to be defined - __per_cpu_load, __per_cpu_start and __per_cpu_end. There were three archs which didn't have it. Update them as follows. * powerpc: can use generic PERCPU() macro. Compile tested for powerpc32, compile/boot tested for powerpc64. * ia64: can use generic PERCPU_VADDR() macro. __phys_per_cpu_start is identical to __per_cpu_load. Compile tested and symbol table looks identical after the change except for the additional __per_cpu_load. * arm: added explicit __per_cpu_load definition. Currently uses unified .init output section so can't use the generic macro. Dunno whether the unified .init ouput section is required by arch peculiarity so I left it alone. Please break it up and use PERCPU() if possible.

2009-03-05[ARM] 5418/1: restore lr before leaving mcountUwe Kleine-König
gcc seems to expect that lr isn't clobbered by mcount, because for a function starting with: static int func(void) { void *ra = __builtin_return_address(0); printk(KERN_EMERG "__builtin_return_address(0) = %pS\n", ra) ... the following assembler is generated by gcc 4.3.2: 0: e1a0c00d mov ip, sp 4: e92dd810 push {r4, fp, ip, lr, pc} 8: e24cb004 sub fp, ip, #4 ; 0x4 c: ebfffffe bl 0 <mcount> 10: e59f0034 ldr r0, [pc, #52] 14: e1a0100e mov r1, lr 18: ebfffffe bl 0 <printk> Without this patch obviously __builtin_return_address(0) yields func+0x10 instead of the return address of the caller. Note this patch fixes a similar issue for the routines used with dynamic ftrace even though this isn't currently selectable for ARM.

After my OMAP3 board has been running for a while, I'm seeing weird latency traces like this: sh-1574 0d.h2 153us : do_timer (tick_do_update_jiffies64) sh-1574 0d.h2 153us : update_wall_time (do_timer) sh-1574 0d.h2 153us!: omap_32k_read (update_wall_time) sh-1574 0d.h2 1883us : update_xtime_cache (update_wall_time) sh-1574 0d.h2 1883us : clocksource_get_next (update_wall_time) sh-1574 0d.h2 1883us+: _spin_lock_irqsave (clocksource_get_next) and after a while: sh-17818 0d.h3 153us : do_timer (tick_do_update_jiffies64) sh-17818 0d.h3 153us : update_wall_time (do_timer) sh-17818 0d.h3 153us!: omap_32k_read (update_wall_time) sh-17818 0d.h3 1915us : update_xtime_cache (update_wall_time) sh-17818 0d.h3 1915us+: clocksource_get_next (update_wall_time) sh-17818 0d.h3 1945us : _spin_lock_irqsave (clocksource_get_next) Turns out that sched_clock() is using cyc2ns(), which returns NTP adjusted time. The sched_clock() frequency should not be adjusted. The patch deletes omap_32k_ticks_to_nsecs() and rewrites sched_clock() to do the conversion using the constant multiplier.

2009-02-27usb: musb: make Davinci *work* in mainlineDavid Brownell
Now that the musb build fixes for DaVinci got merged (RC3?), kick in the other bits needed to get it finally *working* in mainline: - Use clk_enable()/clk_disable() ... the "always enable USB clocks" code this originally relied on has since been removed. - Initialize the USB device only after the relevant I2C GPIOs are available, so the host side can properly enable VBUS. - Tweak init sequencing to cope with mainline's relatively late init of the I2C system bus for power switches, transceivers, and so on. Sanity tested on DM6664 EVM for host and peripheral modes; that system won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also verified on OMAP3.

2009-02-26[ARM] S3C64XX: Do gpiolib configuration earlierMark Brown
arch_initcall() runs after the machine init function which means that any configuration of GPIO pins must currently be done later on, for example in callbacks from drivers. Move the initialisation earlier in order to allow machines to configure GPIOs directly in their init functions rather than having to have a callback invoked later on. Some other ARM platforms use this method. Other solutions for this include providing a special interface for setting up GPIOs en masse, adding callbacks to do the GPIO configuration from devices and doing the GPIO configuration implicitly.

2009-02-22[ARM] at91: fix for Atmel AT91 powersavingAndrei Birjukov
We've discovered that our AT91SAM9260 board consumed too much power when returning from a slowclock low-power mode. RAM self-refresh is enabled in a bootloader in our case, this is how we saw a difference. Estimated ca. 30mA more on 4V battery than the same state before powersaving. After a small research we found that there seems to be a bogus sdram_selfrefresh_disable() call at the end of at91_pm_enter() call, which overwrites the LPR register with uninitialized value. Please find the suggested patch attached. This patch fixes correct restoring of LPR register of the Atmel AT91 SDRAM controller when returning from a power saving mode.
