The member "pgd" in "struct mm_struct" is of type "struct pgd_t *"
rather than "struct pgt_t *", fix the typo.

   memory context and thus its own *pgd*, found in `struct mm_struct` which
   in turn is referenced to in each `struct task_struct`. So tasks have memory
   context in the form of a `struct mm_struct` and this in turn has a
-  `struct pgt_t *pgd` pointer to the corresponding page global directory.
+  `struct pgd_t *pgd` pointer to the corresponding page global directory.
 
 To repeat: each level in the page table hierarchy is a *array of pointers*, so
 the **pgd** contains `PTRS_PER_PGD` pointers to the next level below, **p4d**
