[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [RFC PATCH 5/7] x86/boot: Rename trampoline_{start, end} to boot_trampoline_{start, end}
From: David Woodhouse <dwmw@xxxxxxxxxxxx>
In preparation for splitting the boot and permanent trampolines from
each other. Some of these will change back, but most are boot so do the
plain search/replace that way first, then a subsequent patch will extract
the permanent trampoline code.
Signed-off-by: David Woodhouse <dwmw@xxxxxxxxxxxx>
