This patchset deals with a few kmem failing to output task context
issues.
For CONFIG_VMAP_STACK enabled:
patch 1 deals with "kmem <virtual_address>" when vaddr is
vmalloced stack.
patch 3 deals with "kmem <physical_address>" when vaddr is
vmalloced stack and paddr is converted from the vaddr.
patch 2 is needed by patch 3, it will convert the correct
physical address to virtual address.
For CONFIG_VMAP_STACK not enabled:
patch 4 deals with "kmem <physical_address>", letting it have
the same output as "kmem <virtual_address>", when paddr
is converted from vaddr.
v2 -> v3: Add the kmem <physical_address> case.
v3 -> v4: Add patch 4 case.
