From 3f8e288033ec7f52b570efad7c2eb42741f6d710 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 26 Jul 2011 18:45:54 +0100 Subject: ARM: 7006/1: Migrate to asm-generic wrapper support With d8ecc5c (kbuild: asm-generic support, 2011-04-27) we can remove a handful of asm-generic wrappers in ARM code. Since the generic version of sizes.h doesn't contain SZ_48M, we replace the 4 users of SZ_48M with the equivalent SZ_32M + SZ_16M.

One of the problems is that the ARM implementation doesn't report the function with the BUG() in it, but always reports the PC being in __bug(). The generic implementation doesn't have this problem. Currently we get something like: kernel BUG at fs/proc/breakme.c:35! Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... PC is at __bug+0x20/0x2c With this patch it displays: kernel BUG at fs/proc/breakme.c:35! Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP ... PC is at write_breakme+0xd0/0x1b4 This implementation uses an undefined instruction to implement BUG, and sets up a bug table containing the relevant information. Many versions of gcc do not support %c properly for ARM (inserting a # when they shouldn't) so we work around this using distasteful macro magic. v1: Initial version to replace existing ARM BUG() implementation with something more similar to other architectures. v2: Add Thumb support, remove backtrace whitespace output changes. Change to use macros instead of requiring the asm %d flag to work (thanks to Dave Martin ) v3: Remove old BUG() implementation in favor of this one. Remove the Backtrace: message (will submit this separately). Use ARM_EXIT_KEEP() so that some architectures can dump exit text at link time thanks to Stephen Boyd (although since we always define GENERIC_BUG this might be academic.) Rebase to linux-2.6.git master. v4: Allow BUGS in modules (these were not reported correctly in v3) (thanks to Stephen Boyd for suggesting that.) Remove __bug() as this is no longer needed. v5: Add %progbits as the section flags.
