   - Fix Make < 4.3 build error by using '$(pound)'

   - Fix UML build error by removing 'volatile' qualifier from io
     helpers

   - Fix UML build error by adding 'dma_{alloc,free}_attrs()' helpers

   - Clean gendwarfksyms warnings by avoiding to export '__pfx' symbols

   - Clean objtool warning by adding a new 'noreturn' function for
     1.86.0

   - Disable 'needless_continue' Clippy lint due to new 1.86.0 warnings
