From 2bc7509f62da572925ef33365d4fc16f8b4abdd4 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 15 Jul 2008 17:17:48 +0100 Subject: [ARM] S3C24XX: s3c243xx_clock_register() data can be __initdata Any data being passed to s3c243xx_clock_register() can be marked as __initdata as it is an array of pointers to 'struct clk' that are to be registered on initialisation. The s3c243xx_clock_register function uses this array to register clocks and does not require it to stay around after exit.

Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap). Memory: 512MB 352MB = 864MB total On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000, two 256M RAM banks and vmalloc=768M, this patch gives: Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap).

Current inline asm constraint used in the implementation of prefetch() makes gcc believe that the pointer is dereferenced even though the PLD instruction does not load any data and does not cause a segmentation fault on null pointers, which causes all sorts of interesting results when reaching the end of a linked lists for example. Let's use a better constraint to properly represent the actual usage of the pointer value. Problem reported by Chris Steel.
