hurd: Map brk non-executable
The rest of the heap (backed by individual pages) is already mapped RW. Mapping these pages RWX presents a security hazard. Also, in another branch memory gets allocated using vm_allocate, which sets memory protection to VM_PROT_DEFAULT (which is RW). The mismatch between protections prevents Mach from coalescing the VM map entries. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-Id: <20230625231751.404120-2-bugaevc@gmail.com>
