This fixes issue where empty and unallocated sections are left without
a VMA. Some relocations depend on the section VMA being set even if there
is no data there, as the binary can refer to the symbols. Linker defined
symbols do not contain data -> they can produce empty sections.
This issue is seen when building a loadable file which declares _sctors /
_sdtors linker defined symbols for ctor/dtor sections which are empty.
crt0 references these symbols, so they need to be relocated, but the
section VMA is not set -> they go outside of the addressable range of the
user binary causing a potential crash.
In circbuf_get_read/writeptr, when circbuf is full, off == pos, and
*size = off - pos = 0. So add circbuf_is_full() condition to return
correct *size.

reason:
We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.
up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.
up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.
