ext4 (ext4_alloc_inode) and

We were setting this only in machine__init(), i.e. for the map_groups that
holds the kernel module maps, not for the one used for a thread's executable
mmaps.
Now we are sure that we can obtain the machine where a thread is by going
via thread->mg->machine, thus
The DEBUG_LL will get a dependency on !ARCH_MULTIPLATFORM_STRICT.
So change the corresponding arm/mach defconfigs to disable
ARCH_MULTIPLATFORM_STRICT and avoid break them.

Cache the DWARF debug info for DSO so we don't have to rebuild it for each
address in the DSO.
Note that dso__new() uses calloc() so don't need to set dso->dwfl to NULL.

The early debug could break something when booting 'allmodconfig'
kernels. So we use early console instead of early debug.
The early console didn't work yet on OMAP4460 because of missing
earlycon support and I am working on that.

The current allmodconfig kernel boot fails on OMAP4460. There
are several configuration options that can only work on a subset
of the available machines, and enabling them will break other
machines that may be enabled in a multiplatform kernel.
Now we introduce a CONFIG_ARCH_MULTIPLATFORM_STRICT

Eliminate the DIV_ROUND_UP() and change the loop counter increment to
4 instead. This results in saving 6 instructions in the functions
assembly code.
