> pte_t is used both for software PTE values and for entries stored in a PTE > table, so pte_t * does not distinguish a pointer to a software PTE > value from a pointer to table storage. > > Introduce hw_pte_t as the generic name for a PTE table element. Define it > as a macro alias of pte_t by default. When an architecture selects > ARCH_HAS_HW_PTE_T, define it as a structure containing a pte_t instead. > This preserves the representation while allowing converted architectures > to enforce the distinction at compile time. > > Name the generic wrapper structure __hw_pte_t so architectures can > forward-declare it when pgtable_t must be defined before the generic > hw_pte_t typedef is visible. This avoids header-order dependencies. > > Keep the C type definitions behind an __ASSEMBLY__ check because > architecture assembly sources can include this header indirectly. Include > asm/page.h so consumers such as linux/vmalloc.h retain the page definitions > they previously obtained from that header. > > Signed-off-by: Muhammad Usama Anjum <[email protected]>
