SceLibKernel, not to be confused with Kernel is a user module that implements wrappers to some common syscalls (for example, SceIofilemgr), some user standard library functions (including C standard library), and other common features like heap management. This module is the functionally similar to libc.so.6 on Linux.
Module
This is a user module and exists only in userland. The SELF can be found in os0:us/libkernel.suprx.

Heap
The latest version of dlmalloc is included in SceLibKernel. Most of the assert checks and security are included.
Thread specific data
Each thread owns a private 2048bytes memory region with specific data. The end of this region is pointed by the TPIDRURO register (thus, the start of it is TPIDRURO - 0x800).
