Permit silencing of __deprecated warnings.

2007-10-25T22:10:17Z

The __deprecated marker is quite useful in highlighting the remnants of old APIs that want removing. However, it is quite normal for one or more years to pass, before the (usually ancient, bitrotten) code in question is either updated or deleted. Thus, like __must_check, add a Kconfig option that permits the silencing of this compiler warning. This change mimics the ifdef-ery and Kconfig defaults of MUST_CHECK as closely as possible.

slow down printk during boot

2007-10-16T16:42:49Z

Optionally add a boot delay after each kernel printk() call, crudely measured in milliseconds, with a maximum delay of 10 seconds per printk. Enable CONFIG_BOOT_PRINTK_DELAY=y and then add (e.g.): "lpj=loops_per_jiffy boot_delay=100" to the kernel command line. It has been useful in cases like "during boot, my machine just reboots or the screen goes black" by slowing down printk, (and adding initcall_debug), we can usually see the last thing that happened before the lights went out which is usually a valuable clue.

[POWERPC] ppc64: support CONFIG_DEBUG_PREEMPT

2007-10-03T01:48:44Z

Add CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing get_paca() preemption. Cheat a little, just use debug_smp_processor_id() in the debug version of get_paca(): it contains all the right checks and reporting, though get_paca() doesn't really use smp_processor_id(). Use local_paca for what might have been called __raw_get_paca(). Silence harmless warnings from io.h and lparcfg.c with local_paca - it is okay for iseries_lparcfg_data to be referencing shared_proc with preemption enabled: all cpus should show the same value for shared_proc. Why do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT? I don't know, ppc64 appears to get along fine without it. Signed-off-by: Hugh Dickins Signed-off-by: Paul Mackerras
