2011-06-15xen: support CONFIG_MAXSMPAndrew Jones
The MAXSMP config option requires CPUMASK_OFFSTACK, which in turn requires we init the memory for the maps while we bring up the cpus. MAXSMP also increases NR_CPUS to 4096. This increase in size exposed an issue in the argument construction for multicalls from xen_flush_tlb_others. The args should only need space for the actual number of cpus. Also in 2.6.39 it exposes a bootup problem. BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff8157a1d3>] set_cpu_sibling_map+0x123/0x30d ...

2011-06-14x86 idle: APM requires pm_idle/default_idle unconditionally when a moduleAndy Whitcroft
[ Also from Ben Hutchings <ben@decadent.org.uk> and Vitaliy Ivanov <vitalivanov@gmail.com> ] Commit 06ae40ce073d ("x86 idle: EXPORT_SYMBOL(default_idle, pm_idle) only when APM demands it") removed the export for pm_idle/default_idle unless the apm module was modularised and CONFIG_APM_CPU_IDLE was set. But the apm module uses pm_idle/default_idle unconditionally, CONFIG_APM_CPU_IDLE only affects the bios idle threshold. Adjust the export accordingly.

2011-06-14m68k: use kernel processor defines for conditional optimizationsGreg Ungerer
Older m68k-linux compilers will include pre-defined symbols that confuse what processor it is being targeted for. For example gcc-4.1.2 will pre-define __mc68020__ even if you specify the target processor as -m68000 on the gcc command line. Newer versions of gcc have this corrected. In a few places the m68k code uses defined(__mc68020__) for optimizations that include instructions that are specific to the CPU 68020 and above. When compiling with older compilers this will be true even when we have selected to compile for the older 68000 processors. Switch to using the kernel processor defines, CONFIG_M68020 and friends.

2011-06-14m68knommu: create config options for CPU classesGreg Ungerer

ColdFire It will be useful going forward to have a CONFIG_ option defined for each type. We already have one for ColdFire (CONFIG_COLDFIRE), so add for the other 2 families, CONFIG_M68000 and CONFIG_MCPU32. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2011-06-09exec: delay address limit change until point of no returnMathias Krause
Unconditionally changing the address limit to USER_DS and not restoring it to its old value in the error path is wrong because it prevents us using kernel memory on repeated calls to this function. This, in fact, breaks the fallback of hard coded paths to the init program from being ever successful if the first candidate fails to load. With this patch applied switching to USER_DS is delayed until the point of no return is reached which makes it possible to have a multi-arch rootfs with one arch specific init binary for each of the (hard coded) probed paths. Since the address limit is already set to USER_DS when start_thread() will be invoked, this redundancy can be safely removed.

2011-06-09xen: partially revert "xen: set max_pfn_mapped to the last pfn mapped"Stefano Stabellini
We only need to set max_pfn_mapped to the last pfn mapped on x86_64 to make sure that cleanup_highmap doesn't remove important mappings at _end. We don't need to do this on x86_32 because cleanup_highmap is not called on x86_32. Besides lowering max_pfn_mapped on x86_32 has the unwanted side effect of limiting the amount of memory available for the 1:1 kernel pagetable allocation.
