xen: prevent crashes with non-HIGHMEM 32-bit kernels with largeish memory
 
If this is a non-HIGHMEM 32-bit kernel, then the page structures only go
up to the limit of addressable memory, even if more memory is physically
present.  Don't try to add that extra memory to the balloon.

# In the Xtensa architecture, assembly generates literals which must always
# precede the L32R instruction with a relative offset less than 256 kB.
# Therefore, the .text and .literal section must be combined in parenthesis
# in the linker script, such as: *(.literal .text).
#
# We need to post-process the generated vmlinux.lds scripts to convert
# *(xxx.text) to  *(xxx.literal xxx.text) for the following text sections:
#   .text .ref.text .*init.text .*exit.text .text.*
#
# Replicate rules in scripts/Makefile.build
