2011-08-21ARM: introduce atag_offset to replace boot_paramsNicolas Pitre
The boot_params member of the mdesc structure is used to provide a default physical address for the ATAG list. Since this value is fixed at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET, it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT usage. Let's introduce atag_offset which should contains only the relative offset from PHYS_OFFSET instead of an absolute value, in preparation to move all instance of boot_params over to it.

2011-08-11ARM: mmp: Change the way we use timer 0 as clockevent timer.Lennert Buytenhek

2011-08-11ARM: mmp: Also start timer 1 on boot.Lennert Buytenhek
Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer and as a clockevent timer, the latter by setting up a comparator interrupt to match on 'current_time + delta'. This is problematic if delta is small enough, as that can lead to 'current_time + delta' already being in the past when comparator setup has finished, leading to the requested event not triggering. As there is also a silicon issue that requires stopping a timer's counter while writing to one of its match registers, we'll switch to using two separate timers -- timer 0 as clockevent timer, which we'll start and stop on every invocation of ->set_next_event(), and timer 1 as clocksource timer, which will be free-running. This first patch enables timer 1 on boot, so that we can use it as clocksource timer.

2011-08-10x86-64: Rework vsyscall emulation and add vsyscall= parameterAndy Lutomirski
There are three choices: vsyscall=native: Vsyscalls are native code that issues the corresponding syscalls. vsyscall=emulate (default): Vsyscalls are emulated by instruction fault traps, tested in the bad_area path. The actual contents of the vsyscall page is the same as the vsyscall=native case except that it's marked NX. This way programs that make assumptions about what the code in the page does will not be confused when they read that code. vsyscall=none: Trying to execute a vsyscall will segfault.

2011-08-10x86-64: Wire up getcpu syscallAndy Lutomirski
getcpu is available as a vdso entry and an emulated vsyscall. Programs that for some reason don't want to use the vdso should still be able to call getcpu without relying on the slow emulated vsyscall. It costs almost nothing to expose it as a real syscall. We also need this for the following patch in vsyscall=native mode.

2011-08-10omap: timer: Set dmtimer used as clocksource in autoreload modeHemant Pedanekar
If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the timer stops counting once overflow occurs as it was not set in autoreload mode. This results into timekeeping failure: for example, 'sleep 1' at the shell after the timer counter overflow would hang.
