2011-01-21cris: Convert V10 interrupt handlingThomas Gleixner1-31/+10
Convert the irq_chip functions and install handle_simple_irq for each interrupt. This converts V10 to the flow handling and lets us remove __do_IRQ(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Mikael Starvik <starvik@axis.com>
2011-01-21cris: Use irq handling wrapperThomas Gleixner1-2/+2
Use the wrapper around __do_IRQ() so we can convert V10 and V32 seperately. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Mikael Starvik <starvik@axis.com>
2011-01-21h8300: Use generic irq KconfigThomas Gleixner2-5/+3
Switch to the generic irq Kconfig. h8300 has all irq chips converted to the new functions, so select the GENERIC_HARDIRQS_NO_DEPRECATED switch as well. Fixup the resulting fallout in show_interrupts(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Paul Mundt <lethal@linux-sh.org>
2011-01-21h8300: Convert interrupt handling to flow handlerThomas Gleixner1-12/+3
__do_IRQ is deprecated so h8300 needs to be converted to proper flow handling. The irq chip is simple and does not required any mask/ack/eoi functions, so we can use handle_simple_irq.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes256-269/+269
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2011-01-20lockdep: Move early boot local IRQ enable/disable status to init/main.cTejun Heo1-1/+1
During early boot, local IRQ is disabled until IRQ subsystem is properly initialized. During this time, no one should enable local IRQ and some operations which usually are not allowed with IRQ disabled, e.g. operations which might sleep or require communications with other processors, are allowed. lockdep tracked this with early_boot_irqs_off/on() callbacks. As other subsystems need this information too, move it to init/main.c and make it generally available. While at it, toggle the boolean to early_boot_irqs_disabled instead of enabled so that it can be initialized with %false and %true indicates the exceptional condition.

This reverts commit 86b1e8dd83cb ("x86: Make relocatable kernel work with new binutils"). Markus Trippelsdorf reported a boot failure caused by this patch. The real solution to the original patch will likely involve an arch-generic solution to define an overlaid jiffies_64 and jiffies variables.

2011-01-18MIPS: Malta: enable Cirrus FB consoleAurelien Jarno1-0/+3
While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB.

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth.

2011-01-18x86: Make relocatable kernel work with new binutilsShaohua Li1-2/+9
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make boot panic. According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to 2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is using such binutils. See: http://sourceware.org/bugzilla/show_bug.cgi?id=12327 The reason of the boot panic is that we have 'jiffies = jiffies_64;' in vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is warning saying jiffies is an absolute address and can't be relocatable. At runtime, jiffies will have virtual address 0.
