Hi Andi, This is a series of patches based on your latest queue (as of the other day, at least). It includes: - the most recent patch to compute the appropriate amount of percpu space to allocate, using a separate reservation for modules where needed. - make the percpu sections page-aligned, so that percpu variables can be page aligned if needed (which is used by gdt_page) -

There are ~4300 uses of pr_warn and ~250 uses of the older pr_warning in the kernel source tree. Make the use of pr_warn consistent across all kernel files. This excludes all files in tools/ as there is a separate define pr_warning for that directory tree and pr_warn is not used in tools/. Done with 'sed s/\bpr_warning\b/pr_warn/' and some emacsing. Miscellanea: o Coalesce formats and
