2011-02-01arm: mach-omap2: board-rm680: fix rm680_vemmc regulator constraintsAaro Koskinen
With the commit 757902513019e6ee469791ff76f954b19ca8d036 (regulator: Factor out voltage set operation into a separate function) fixed voltage regulator setup will fail if there are voltage constraints defined. This made MMC unusable on this board. Fix by just deleting those redundant constraints.

Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs supporting SMP must have the new CPU ID format, so check for this first. Then check for ARM11MPCore, which fails the MPIDR check. Lastly check the MPIDR reports multiprocessing extensions and that the CPU is part of a multiprocessing system.

Disable the initrd if the passed address already overlaps the reserved region.

Little endian system needs to check OF_DT_HEADER but it is swapped because it is in big-endian.

There is used the fact that if you write 0x1 as word and load it as byte then you get for big-endian zero and 1 for little-endian. Signed-off-by: Michal Simek <monstr@monstr.eu>

2011-01-27perf: Fix Pentium4 raw event validationStephane Eranian
This patch fixes some issues with raw event validation on Pentium 4 (Netburst) based processors. As I was testing libpfm4 Netburst support, I ran into two problems in the p4_validate_raw_event() function: - the shared field must be checked ONLY when HT is on - the binding to ESCR register was missing The second item was causing raw events to not be encoded correctly compared to generic PMU events. With this patch, I can now pass Netburst events to libpfm4 examples and get meaningful results: $ task -e global_power_events:running:u noploop 1 noploop for 1 seconds 3,206,304,898 global_power_events:running Signed-off-by: Stephane Eranian <eranian@google.com> Acked-by: Cyrill Gorcunov <gorcunov@openvz.org> Cc: peterz@infradead.org Cc: paulus@samba.org Cc: davem@davemloft.net Cc: fweisbec@gmail.com Cc: perfmon2-devel@lists.sf.net Cc: eranian@gmail.com Cc: robert.richter@amd.com Cc: acme@redhat.com Cc: gorcunov@gmail.com Cc: ming.m.lin@intel.com LKML-Reference: <4d3efb2f.1252d80a.1a80.ffffc83f@mx.google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-01-27xen/setup: Route halt operations to safe_halt pvop.Stefano Stabellini
With this patch, the cpuidle driver does not load and does not issue the mwait operations. Instead the hypervisor is doing them (b/c we call the safe_halt pvops call). This fixes quite a lot of bootup issues wherein the user had to force interrupts for the continuation of the bootup. Details are discussed in: http://lists.xensource.com/archives/html/xen-devel/2011-01/msg00535.html [v2: Wrote the commit description] Reported-by: Daniel De Graaf <dgdegra@tycho.nsa.gov> Tested-by: Daniel De Graaf <dgdegra@tycho.nsa.gov> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-01-27xen/e820: Guard against E820_RAM not having page-aligned size or start.Stefano Stabellini
Under Dell Inspiron 1525, and Intel SandyBridge SDP's the BIOS e820 RAM is not page-aligned: [ 0.000000] Xen: 0000000000100000 - 00000000df66d800 (usable) We were not handling that and ended up setting up a pagetable that included up to df66e000 with the disastrous effect that when memset(NODE_DATA(nodeid), 0, sizeof(pg_data_t)); tried to clear the page it would crash at the 2K mark. Initially reported by Michael Young @ http://lists.xensource.com/archives/html/xen-devel/2011-01/msg00108.html The fix is to page-align the size and also take into consideration the start of the E820 (in case that is not page-aligned either). This fixes the bootup failure on those affected machines. This patch is a rework of the Micheal A Young initial patch and considers the case if the start is not page-aligned.

2011-01-26OMAP3: PM: fix save secure RAM to restore MPU power stateKevin Hilman
Currently, on HS/EMU devices, MPU power state forced to on during PM init by the save secure RAM code. Rather than forcing the state of MPU powerdomain to on, simply read the current value and restore it after the ROM code has run. This only affects the !CPUidle case since when CPUidle is enabled, the MPU power state is dynamically changed by CPUidle. In the !CPUidle case, MPU power state is initialized once at init and never touched. Acked-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock.
