Subject: [PATCH v3 01/23] mm/memblock: debug: correct displaying of upper memory boundary
Date: Mon, 9 Dec 2013 16:50:34 -0500 [thread overview]
Message-ID: <1386625856-12942-2-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1386625856-12942-1-git-send-email-santosh.shilimkar@ti.com>
From: Grygorii Strashko <grygorii.strashko@ti.com>
When debugging is enabled (cmdline has "memblock=debug") the memblock
will display upper memory boundary per each allocated/freed memory range
wrongly. For example:
memblock_reserve: [0x0000009e7e8000-0x0000009e7ed000] _memblock_early_alloc_try_nid_nopanic+0xfc/0x12c
The 0x0000009e7ed000 is displayed instead of 0x0000009e7ecfff
Hence, correct this by changing formula used to calculate upper memory
boundary to (u64)base + size - 1 instead of (u64)base + size everywhere
in the debug messages.
