[Qemu-devel] [PATCH v1 1/1] linux-user: Fix webkitgtk hangs on 32-bit x86 target

[Alistair Francis]

Since commit "linux-user: Tidy and enforce reserved_va initialization"
(18e80c55bb6ec17c05ec0ba717ec83933c2bfc07) the Yocto webkitgtk build
hangs when cross compiling for 32-bit x86 on a 64-bit x86 machine using
musl.

To fix the issue reduce the MAX_RESERVED_VA macro to be a closer match
to what it was before the problematic commit.
