Yes. Kurt's recent patch for parsing PT_GNU_STACK section introduced
this change.

Here is the relevant hunk.
-#define PAGE_COPY      __pgprot(__ACCESS_BITS | _PAGE_PL_3 |
_PAGE_AR_RX)
+#define PAGE_COPY      __pgprot(__ACCESS_BITS | _PAGE_PL_3 |
_PAGE_AR_R)
+#define PAGE_COPY_EXEC __pgprot(__ACCESS_BITS | _PAGE_PL_3 |
_PAGE_AR_RX)
