Subject: [PATCH 001/001] mm: Use KERN_INFO log level for memory configuration
boot messages
From: Orion Poplawski <orion@...a.nwra.com>
While trying look at just "warning" or stronger messages with "journalctl --priority 0..4" I keep
seeing:
Sep 29 07:10:29 barry kernel: Zone ranges:
Sep 29 07:10:29 barry kernel: DMA [mem 0x00001000-0x00ffffff]
Sep 29 07:10:29 barry kernel: DMA32 [mem 0x01000000-0xffffffff]
Sep 29 07:10:29 barry kernel: Normal [mem 0x100000000-0x61fffffff]
Sep 29 07:10:29 barry kernel: Movable zone start for each node
Sep 29 07:10:29 barry kernel: Early memory node ranges
Sep 29 07:10:29 barry kernel: node 0: [mem 0x00001000-0x0009dfff]
Sep 29 07:10:29 barry kernel: node 0: [mem 0x00100000-0xdfdf8fff]
Sep 29 07:10:29 barry kernel: node 0: [mem 0x100000000-0x61fffffff]
Sep 29 07:10:29 barry kernel: Built 1 zonelists in Zone order, mobility grouping on. Total pages
Sep 29 07:10:29 barry kernel: Policy zone: Normal
Sep 29 07:10:29 barry kernel: Memory: 24673284K/25163352K available (7245K kernel code, 1127K rwd
which strike me as purely informational. This patch sets the level of these messages accordingly.
This is to current git master.
