This change to blk_queue_may_bounce() in block/blk.h will only affect systems with the following configuration:
- 32-bit ARM architecture
- Physical DDR memory greater than 1GB
- CONFIG_HIGHMEM enabled
- Virtual memory split of 1GB for kernel and 3GB for userspace
Under these conditions, the logic for buffer bouncing is relevant because the kernel may need to handle memory above the low memory threshold, which is typical for highmem-enabled 32-bit systems with large RAM. On other architectures or configurations, this code path will not be exercised.
You did not answer most of the questions I asked for some reason :(
