2009-12-09ARM: Do not allow the probing of the local timerVarun Swara
Since this IRQ descriptor doesn't have an action registered, it is allowed for probing via probe_irq_on/off() and it will be disabled by the latter function. This patch sets the IRQ_NOPROBE status bit for the local timer descriptor. Signed-off-by: Varun Swara <Varun.Swara@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-09-28ARM: Fix __cpuexit section mismatch warningsRussell King
Fix: WARNING: vmlinux.o(.text+0x247c): Section mismatch in reference from the function cpu_idle() to the function .cpuexit.text:cpu_die() The function cpu_idle() references a function in an exit section. Often the function cpu_die() has valid usage outside the exit section and the fix is to remove the __cpuexit annotation of cpu_die. WARNING: vmlinux.o(.cpuexit.text+0x3c): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel() The function __cpuexit cpu_die() references a function __cpuinit secondary_start_kernel(). This is often seen when error handling in the exit function uses functionality in the init path. The fix is often to remove the __cpuinit annotation of secondary_start_kernel() so it may be used outside an init section. Sam says: > The annotation of cpu_die() is wrong. > To be annotated __cpuexit the function shall: > - be used in exit context and only in exit context with HOTPLUG_CPU=n > - be used outside exit context with HOTPLUG_CPU=y So, this also means __cpu_disable(), __cpu_die() and twd_timer_stop() are also wrong. However, removing __cpuexit from cpu_die() creates: WARNING: vmlinux.o(.text+0x6834): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel() The function cpu_die() references the function __cpuinit secondary_start_kernel(). This is often because cpu_die lacks a __cpuinit annotation or the annotation of secondary_start_kernel is wrong. so fix this using __ref.
