* kernel: Implement SetMemoryPermission syscall This commit implement the SetMemoryPermission syscall accurately. This also fix KMemoryPermission not being an unsigned 32 bits type and add the "DontCare" bit (used by shared memory, currently unused in Ryujinx) * Update MemoryPermission mask * Address gdkchan's comments * Fix a nit * Address gdkchan's comment
