0edb290951 symtab_findbyname: just retun NULL for NULL symtab
The condition is not fatal at all.
It's better to let the caller handle the failure.

2a6de301ee net/tcp: transformed NET_TCP_FAST_RETRANSMIT_WATERMARK option to boolean.
According to RFC 5681 (3.2) the TCP Fast Retransmit algorithm should start
if the threshold of 3 duplicate ACKs is reached.
Thus the threshold should be a constant, not an integer option.

81188d9c94 Extend the RISC-V PMP functionality
- Add test for mode support, which is architecture dependent
- Add tests for address alignment and region size
- Add option to query for access rights
 - The function goes through every PMP entry and tests if an address
   range from [base, base+size] has been configured for desired
   access rights.
 - If several PMP entries match the range and access rights, the
   information is combined
 - End result is either no access, a partial match was found, or a full
   match was found. Details about the partial match are not provided.

The intent for testing access rights and not just blindly applying them
is a case where they are already set in e.g. a bootloader. In this
case, nothing should be done, unless the configuration does not match,
in which case the software must not continue further.

8a4881c4e5 Implement CONFIG_BUILD_PROTECTED with MMU
NOTE: THIS ONLY WORKS WHEN KERNEL RUNS IN M-MODE FOR NOW

This frees the PMP for other use, e.g. HART memory separation.

The page tables are statically allocated, 1 per level.

This feature is now behind CONFIG_MPFS_USE_MMU_AS_MPU, because
only the MPFS target supports this (others are not tested).

If the MMU is used for memory separation within a HART, the PMP must
still be configured to allow user access to the memory mapped for the
HART, because PMP *rekoves* access by default. At this point all of
the user memory as well as the kernel RAM are opened.

A more flexible solution for PMP configuration will follow.

7eb726d57f Add proper user/kernel space linker scripts for knsh target
The old implementation used the default ld.script for the kernel side
which did not obey the memory.ld limits whatsoever.

Also, provide the user space addresses from the linker script to get rid
of the pre-processor macros that define (incorrect) default values for
the user space composition.
