Subject: [PATCH 5/7] exec: Promote TARGET_PAGE_MASK to target_long
Date: Thu, 19 Sep 2019 16:29:50 -0700	[thread overview]
Message-ID: <20190919232952.6382-6-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190919232952.6382-1-richard.henderson@linaro.org>

There are some uint64_t uses that expect TARGET_PAGE_MASK to
extend for a 32-bit, so this must continue to be a signed type.
Define based on TARGET_PAGE_BITS not TARGET_PAGE_SIZE; this
will make a following patch more clear.

This should not have a functional effect so far.
