[h8300] move include/asm-h8300 to arch/h8300/include/asm
Done as a script (well, a single "git mv" actually) on request from Yoshinori Sato as a way to avoid a huge diff.

5/* format of page table entries that correspond to shared memory pages
6 currently out in swap space (see also mm/swap.c):
7 bits 0-1 (PAGE_PRESENT) is = 0
8 bits 8..2 (SWP_TYPE) are = SHM_SWP_TYPE
9 bits 31..9 are used like this:
10 bits 15..9 (SHM_ID) the id of the shared memory segment
11 bits 30..16 (SHM_IDX) the index of the page within the shared memory segment
12 (actually only bits 25..16 get used since SHMMAX is so low)
13 bit 31 (SHM_READ_ONLY) flag whether the page belongs to a read-only attach

15/* on the m68k both bits 0 and 1 must be zero */
16/* format on the sun3 is similar, but bits 30, 31 are set to zero and all
17 others are reduced by 2. --m */
