Hi,
In @.4 for i386 VMALLOC_START is computed as:
#define VMALLOC_START (((unsigned long)high_memory \
+ 2*VMALLOC_OFFSET-1) & \
~(VMALLOC_OFFSET-1))
I am not sure why do we need to AND in this way.
If I am getting the concept right, I think that if a
system has 32MB of RAM then
VMALLOC_START =
PAGE_OFFSET +
(16 + 8) << 20 (For Kernel Image and ZONE_DMA) +
(32 << 20) / PAGE_SIZE +
VM_ALLOC_OFFSET
Is that right?
Thanks in advance.
