In 5c6064 the qemuarm* machines gained vmalloc=256, because in testing Bruce was seeing problems when the vmalloc area was too big for the memory size of the machine (eg 256MB). The intention was for the area to be very small, but 256 bytes is too small and the kernel sets a minimal vmalloc area of 16MiB: [ 0.000000] vmalloc area is too small, limiting to 16MiB However, a 16MiB area is too small and results in pages of messages when you try and use the system: [ 242.822481] vmap allocation for size 4100096 failed: use vmalloc=<size> to increase size There have been a number of changes since this commit, remove the explicit vmalloc argument and use the default. I've tested that the system still boots locally.
