2010-08-05MIPS: tracing: Fix the indentation of mcount.SWu Zhangjin1-3/+3
The commit "MIPS: Tracing: Cleanup the arguments passing of prepare_ftrace_return" has moved the "jal prepare_ftrace_return" instruction after the handling of the 3rd argument but forgot to remove the superfluous space before the related instructions.

2010-08-05MIPS: Enable heap randomization.David Daney2-0/+33
Based somewhat on the PPC implementation. 32-bit processes have the heap randomized in an 8MB space, 256MB for 64-bit processes.

2010-08-05MIPS: EMMA2RH: Remove EMMA2RH_CPU_CASCADEShinya Kuribayashi2-2/+1
Although all EMMAxxx SoCs can support IP2 and IP3 hardware interrupts, current EMMA2RH plat_irq_dispatch() supports IP2 only. We can make it configurable in the future, but for the time being, would like to make things explicitly allcated to IP2 in accordance with plat_irq_dispatch().

2010-08-05MIPS: EMMA2RH: Remove useless CPU_IRQ_BASEShinya Kuribayashi2-7/+5
For historical reasons, we used to put MIPS CPU IRQs behind SoC-specific IRQs in the queue, and have been using CPU_IRQ_BASE as MIPS_CPU_IRQ_BASE. In recent years, however, we've brought it back to normal order, and now CPU_IRQ_BASE just redefines the generic MIPS_CPU_IRQ_BASE. At the same time, NUM_CPU_IRQ is also removed as useless.

2010-08-05MIPS: AR7: rewrite of cpmac_get_mac()Alexander Clouter1-27/+15
Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could be replaced with a single call to sscanf(), looks cleaner to me at least. The result is 100 bytes trimmed off the size of a compiled cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails over to using random_ether_addr() when an attempt to parse an invalid MAC address is made.

2010-08-05MIPS: PowerTV: Simplify command line handling and needed config changesDavid VomLehn2-78/+201
Additional changes to Youichi Yuasa's command line simplication code The PowerTV platform uses a non-standard way to get the kernel command line--we insert a built-in command line into arcs_cmdline and to get additional command line information from the bootloader via a pointer in the a1 register. It is necessary to insert a space between to the two strings or the last argument from arcs_cmdline and the first argument from the bootloader may be inadvertantly combined. It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the default command line to an empty string to get the simplified code to work properly in the PowerTV environment.

2010-08-05printk: fix delayed messages from CPU hotplug eventsKevin Cernekee1-2/+31
When a secondary CPU is being brought up, it is not uncommon for printk() to be invoked when cpu_online(smp_processor_id()) == 0. The case that I witnessed personally was on MIPS: http://lkml.org/lkml/2010/5/30/4 If (can_use_console() == 0), printk() will spool its output to log_buf and it will be visible in "dmesg", but that output will NOT be echoed to the console until somebody calls release_console_sem() from a CPU that is online. Therefore, the boot time messages from the new CPU can get stuck in "limbo" for a long time, and might suddenly appear on the screen when a completely unrelated event (e.g. "eth0: link is down") occurs. This patch modifies the console code so that any pending messages are automatically flushed out to the console whenever a CPU hotplug operation completes successfully or aborts. The issue was seen on 2.6.34. Original patch by Kevin Cernekee with cleanups by akpm and additional fixes by Santosh Shilimkar. This patch superseeds https://patchwork.linux-mips.org/patch/1357/.
