virtio_balloon: prevent pfn array overflow [ Upstream commit 6e9826e77249355c09db6ba41cd3f84e89f4b614 ] Make sure, at build time, that pfn array is big enough to hold a single page. It happens to be true since the PAGE_SHIFT value at the moment is 20, which is 1M - exactly 256 4K balloon pages. Signed-off-by: Michael S.
