From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When NR_CPUS increases the fixmap might need more than the page allocated by head_32.S. This patch introduces the logic to calculate the additional memory that is going to be required by early_ioremap_page_table_range_init: - enough memory to allocate the pte pages needed to cover the fixmap virtual memory range, minus the single page allocated by head_32.S; - account for the pag...

...r your reply. The usecase here is just trying to construct a valid ELF. The lld linker needs to handle all sorts of code written in assembly as well as 'C'. The usecase is just one example of it. I have also seen similiar code in http://lxr.free-electrons.com/source/arch/powerpc/kernel/head_32.S?a=powerpc which has global and local labels. You are right, that the function has multiple entry points. You can remove the .local directive too. Thanks Shankar Easwaran On 11/15/2012 9:47 PM, Nick Kledzik wrote: > Shankar, > > Let's step back.
