From 6f9f59ee2e254a7e997985d8eb708930da49245a Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Thu, 1 Nov 2012 13:58:17 +0800 Subject: [PATCH] mtd: cmdlinepart: fix the overflow of big mtd partitions When the kernel parses the following cmdline #mtdparts=gpmi-nand:16m(boot),16m(kernel),1g(home),4g(test),-(usr) for a big nand chip Micron MT29F64G08AFAAAWP(8GB), we got the following wrong result: ............................................. "mtd: partition size too small (0)" ............................................. We can not get any partition. The "4g(test)" partition triggers a overflow of the "size". The memparse() returns 4g to the "size", but the size is "unsigned long" type, so a overflow occurs, the "size" becomes zero in the end. This patch changes the "size"/"offset" to "unsigned long long" type, and replaces the UINT_MAX with ULLONG_MAX for macros SIZE_REMAINING and OFFSET_CONTINUOUS.
