Dear All I am facing an issue during bootup of the android JB device. During my analysis, i came to know that it is taking 3sec time in freeing the high memory pages, while other devices are taking almost no time. the code is in arch/arm/mm/init.c , free_highpages(). We have almost 1456MB of memory for HIGHMEM and during freeing all the pages, it is taking this much time. Now my question is, 1) free_area() function has anything to do with the hardware? Like DDR frequency settings etc.., 2) Is this because of software problem..? I am kind of struck here, since this part of the code is right in mm-core, any pointers in resolving the issue is highly appreciated.. -- With regards, Sandeep Kumar Anantapalli,
