cxl devices typically access memory using an MMU in much the same way as
the CPU, and each context includes a state register much like the MSR in
the CPU. Like the CPU, the state register includes a bit to enable
relocation, which we currently always enable.
In some cases, it ma

When boot memory size for fadump is not specified, memory is reserved
for fadump based on system RAM size. As the system RAM size increases,
the memory reserved for fadump increases as well. This patch sets an
upper limit on the memory reserved for fadump, to avoid reserving
excess memory.
Signed-
Currently, memory for fadump can be specified with fadump_reserve_mem=size,
where only a fixed size can be specified. This patch tries to extend this
syntax to support conditional reservation based on memory size, with the
below syntax:
fadump_reserve_mem=:[,:,...]
This syntax helps using
Kernel parameter 'nr_cpus' can be used to limit the maximum number
of processors that an SMP kernel could support. This patch extends
this to fadump by introducing 'fadump_nr_cpus' parameter that can
help in booting fadump kernel on a lower memory footprint.
