Subject: sparc64: fix build regession

Commit ea1e7ed33708 triggers build regression on sparc64.

include/linux/mm.h:1391:2: error: implicit declaration of function 'pgtable_cache_init' [-Werror=implicit-function-declaration]
arch/sparc/include/asm/pgtable_64.h:978:13: error: conflicting types for 'pgtable_cache_init' [-Werror]

It happens due headers include loop:

<linux/mm.h> -> <asm/pgtable.h> -> <asm/pgtable_64.h> ->
	<asm/tlbflush.h> -> <asm/tlbflush_64.h> -> <linux/mm.h>

Let's drop <linux/mm.h> include from asm/tlbflush_64.h.
Build tested with allmodconfig.

Subject: sparc64: merge fix

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/mm/init_64.c: In function 'pte_alloc_one':
arch/sparc/mm/init_64.c:2568:9: error: unused variable 'pte' [-Werror=unused-variable]

Caused by the merge between commit 37b3a8ff3e08 ("sparc64: Move from 4MB
to 8MB huge pages") and commit 1ae9ae5f7df7 ("sparc: handle
pgtable_page_ctor() fail") (I had the following merge fix in linux-next,
but it didn't seem to propagate upstream - may have forgotten to point it
out :-().
