exec.c: Remove static allocation of sub_section of sub_page
Allocate sub_section dynamically. Remove dependency on TARGET_PAGE_SIZE to make run-time page size detection for arm platforms. Signed-off-by: Vijaya Kumar K <vijayak@cavium.com> Message-id: 1465808915-4887-3-git-send-email-vijayak@caviumnetworks.com [PMM: use flexible array member rather than separate malloc so we don't need an extra pointer deref when using it] Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
