Subject: x86: headers cleanup - boot.h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=95c4bff0308eb0819436b730a836846d3e784657;p=mv-sheeva.git

x86: headers cleanup - boot.h

Impact: cleanup

'make headers_check' warn us about leaking of kernel private
(mostly compile time vars) data to userspace in headers. Fix it.

Neither BOOT_HEAP_SIZE, BOOT_STACK_SIZE refs
was found by searching thru net (ie in user-space area)
so fence this all by __KERNEL__ guard.
