Hello, This series has been split into two patches, one for arm and one for x86. I figured that this was easier than doing it as a single combined patch, especially as the changes are functionally independent. x86 has been boot tested, but arm has not even been compile tested as I lack a suitable cross compiler. However, the changes are just text replacement, so I dont expect any issues. The

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) -

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than
