Subject: linux-user: Do not subtract offset from end address
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ccf661f827faf700b03a30076b5f944e8f787280;p=qemu.git

linux-user: Do not subtract offset from end address

When computing the upper address of a program segment, do not subtract the
offset from the virtual address; instead compute the sum of the virtual address
and the memory size.
