memblock: use memblock_free for freeing virtual pointers

2021-11-06T20:30:41+00:00

Rename memblock_free_ptr() to memblock_free() and use memblock_free()
when freeing a virtual pointer so that memblock_free() will be a
counterpart of memblock_alloc()

The callers are updated with the below semantic patch and manual
addition of (void *) casting to pointers that are represented by
unsigned long variables.

    @@
    identifier vaddr;
    expression size;
    @@
    (
    - memblock_phys_free(__pa(vaddr), size);
    + memblock_free(vaddr, size);

    + memblock_free(vaddr, size);

memblock: rename memblock_free to memblock_phys_free

2021-11-06T20:30:41+00:00

Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().

The callers are updated with the below semantic patch:

    @@
    expression addr;
    expression size;
    @@
    - memblock_free(addr, size);
    + memblock_phys_free(addr, size);

memblock: drop memblock_free_early_nid() and memblock_free_early()

2021-11-06T20:30:41+00:00

memblock_free_early_nid() is unused and memblock_free_early() is an
alias for memblock_free().

Replace calls to memblock_free_early() with calls to memblock_free() and
remove memblock_free_early() and memblock_free_early_nid().

2021-10-06T19:28:02+00:00

Enable the 'muhu' instruction, complementing the existing 'mulu', needed
to implement a MIPS32 BPF JIT.

Also fix a typo in the existing definition of 'dmulu'.
