[PATCH] Fix kexec compile error, undeclared 'vmlist'

[PATCH] Fix kexec compile error, undeclared 'vmlist'

[Jens Axboe]

Hi,

Current -git fails to compile, at least on ppc:

kernel/kexec.c: In function 'crash_save_vmcoreinfo_init':
kernel/kexec.c:1374: error: 'vmlist' undeclared (first use in this function)
kernel/kexec.c:1374: error: (Each undeclared identifier is reported only once
kernel/kexec.c:1374: error: for each function it appears in.)
kernel/kexec.c:1410: error: invalid use of undefined type 'struct vm_struct'

It's missing a vmalloc.h include, introduced by
acd99dbf54020f5c80b9aa2f2ea86f43cb285b02.

So this was already fixed and pushed out by Tony, so nevermind the extra
noise. Apparently I had pulled this morning just before, so missed the
last few changes.
