| |
Hi Andi,
This patch was previously part of relocatable kernel series but now I have forked it out as it is required for 2.6.19 kernels and relocatable kernel patches have to wait.
Please apply.
Thanks Vivek
o Explicitly align data segment to PAGE_SIZE boundary otherwise depending on config options and tool chain it might be placed on a non PAGE_SIZE aligned boundary and vmlinux loaders like kexec fail when they encounter a PT_LOAD type segment which is not aligned to PAGE_SIZE boundary.
