Fix for reading compressed kdump dumpfiles from systems with physical
memory located at extraordinarily high addresses. In a system with
a physical address range from 0x602770ecf000 to 0x6027ffffffff, the
crash utility fails during session initialization due to an integer
overflow, ending with the error message "crash: vmlinux and vmcore
do not match!".

Subject: [PATCH 3/4] kaslr: cleanup how to set values to the arguments of
calc_kaslr_offset()
Setting values of the arguments of calc_kaslr_offset() should be done
at the end of the function. Currently, they are set in the middle
where their values could still be changed according to
get_kaslr_offset_from_vmcoreinfo(). This behavior will be problematic
in the later commits when we implement a trial-and-error approach
because the value of kaslr_offset could be passed to the outside of
calc_kaslr_offset() unexpectedly. Thus, fix this first.

Subject: [PATCH 4/4] kaslr: fix failure of calculating kaslr_offset due to an
sadump format restriction
We faced recently a memory dump collected by sadump where unused part
of register values are non-zero. For the crash dump, calculating
kaslr_offset fails because it is based on the assumption that unused
part of register values in the sadump format are always zero cleared.
The problem is that used and unused part of register values are
rigorously indistinguishable in the sadump format. Although there is
kernel data structure that represents a map between logical cpu
numbers and lapic ids, they cannot be used in order to calculate
kaslr_offset.
To fix this, we have no choice but use a trial-and-error approach: try
to use each entry of register values in order until we find a good
pair of cr3 and idtr by which we can refer to linux_banner symbol as
expected.
This fix is for the sadump specific issue, so there is no functional
change for the other crash dump formats.
[ lijiang: adjust the code indent. ]
