I have a 4.7MB application that runs on the 2.6.26 kernel (Freescale BSP) and am working to make it run on the 2.6.38 kernel released in the ColdFire BSP in Feb 2012.  I'm concerned about memory allocation as my first attempt to run on the 38 kernel appears to be using 2^n memory allocation vs. allocation that sizes just 1-page over the application.

1) Can anyone tell me the exact kernel config name that needs to be adjusted for the 38 kernel to set the default memory allocation?
	- Older posts indicate modules like page_alloc2 or Kmalloc2 control this so I'm going to investigate these in more detail
	- RTFMing indicate that this might be the area but I don't see it in the 38 version (LTIB or make menucionfig):
		menuconfig -> kernel settings -> general settings, try enabling either the "Permit large allocations" setting, or the "non-power-of-2"

2) Historically, we use LTIB to create the kernel.  Does LTIB expose most/all settings of the 2.6.38 kernel?  Can it be out of sync with the make menuconfig uClinus kernel?

Thanks!
