2009-10-12x86: fix kernel panic on 32 bits when profilingH. Peter Anvin
Latest kernel has a kernel panic in booting on i386 machine when profile=2 setting in cmdline. It is due to 'sp' being incorrect in profile_pc(). BUG: unable to handle kernel NULL pointer dereference at 00000246 IP: [<c01288b6>] profile_pc+0x2a/0x48 *pde = 00000000 Oops: 0000 [#1] SMP This differs from the original version by Alex Shi in that we use the kernel_stack_pointer() inline already defined in <asm/ptrace.h> for this purpose, instead of #ifdef.

2009-09-16x86: platform: Fix section annotationsThomas Gleixner
init_IRQ() and x86_late_time_init() are missing __init annotations. The x86 platform ops variables are annotated, but the annotation needs to be put between the variable name and the "=" of the initializer. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-31x86: Move tsc_init to late_time_initThomas Gleixner
We do not need the TSC before late_time_init. Move the tsc_init to the late time init code so we can also utilize HPET for calibration (which we claimed to do but never did except in some older kernel version). This also helps Moorestown to calibrate the TSC with the AHBT timer which needs to be initialized in late_time_init like HPET. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
