Merge core only libs into the target make-files.
Use base-hw specific Board drivers that inherit
from generic Board_base.
Use Page_flags::access_t instead of additional
page_flags_t.
Fix#570
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.
Related to issue #526.
Add 'resume_faulter' syscall that is similar to 'resume_thread', but
is called only when resuming a thread after resolving its pagefault.
This way the kernel can flush caches after resolving a pagefault. This is
because by now the MMU doesn't use caches when doing a pagetable walk.
'Page_flags' maps application-specific memory attributes
to the TLB-specific memory attributes. Thereby it avoids
functions with lots of parameters, by declaring appropriate
bitfields on a single POD value.
Enable caches. Core is not cached by now. This is because kernel
creates core space and doesn't know any memory attributes by now.
Cacheable pages are cached write-through without write-allocate.
Caching and write-combining is not supported for IOMEM by now.
