[GitHub] [nuttx] pussuw opened a new pull request, #8180: riscv/addrenv: Do not free physical memory for SHM area

pussuw opened a new pull request, #8180:
URL: https://github.com/apache/nuttx/pull/8180

   ## Summary
   Fix crash when SHM memory is freed twice into the page pool.
   
   SHM area is just mapped memory, the physical backup is not owned by the process, so the process must not free it.
   
   In ARM this is already handled as the regions are destroyed one by one, while this implementation does a page directory walk instead.
   ## Impact
   riscv only
   ## Testing
   icicle:knsh
