      x86: fix section mismatch warning · 659d2618
      由 Rakib Mullick 提交于 
      Here function vmi_activate calls a init function activate_vmi , which
causes the following section mismatch warnings:

  LD      arch/x86/kernel/built-in.o
WARNING: arch/x86/kernel/built-in.o(.text+0x13ba9): Section mismatch
in reference from the function vmi_activate() to the function
.init.text:vmi_time_init()
The function vmi_activate() references
the function __init vmi_time_init().
This is often because vmi_activate lacks a __init
annotation or the annotation of vmi_time_init is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x13bd1): Section mismatch
in reference from the function vmi_activate() to the function
.devinit.text:vmi_time_bsp_init()
The function vmi_activate() references
the function __devinit vmi_time_bsp_init().
This is often because vmi_activate lacks a __devinit
annotation or the annotation of vmi_time_bsp_init is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x13bdb): Section mismatch
in reference from the function vmi_activate() to the function
.devinit.text:vmi_time_ap_init()
The function vmi_activate() references
the function __devinit vmi_time_ap_init().
This is often because vmi_activate lacks a __devinit
annotation or the annotation of vmi_time_ap_init is wrong.

Fix it by marking vmi_activate() as __init too.

      x86, debug: remove early_printk() #ifdefs from head_32.S · 34707bcd
      由 Ingo Molnar 提交于 
      Impact: cleanup

Remove such constructs:

 #ifdef CONFIG_EARLY_PRINTK
        call early_printk
 #else
        call printk
 #endif

Not only are they ugly, they are also pointless: a call to printk()
maps to early_printk during early bootup anyway, if CONFIG_EARLY_PRINTK
is enabled.

      x86: unmask CPUID levels on Intel CPUs, fix · 99fb4d34
      由 Ingo Molnar 提交于 
      Impact: fix boot hang on pre-model-15 Intel CPUs

rdmsrl_safe() does not work in very early bootup code yet, because we
dont have the pagefault handler installed yet so exception section
does not get parsed. rdmsr_safe() will just crash and hang the bootup.

So limit the MSR_IA32_MISC_ENABLE MSR read to those CPU types that
support it.

      x86: filter CPU features dependent on unavailable CPUID levels · b38b0665
      由 H. Peter Anvin 提交于 
      Impact: Fixes potential crashes on misconfigured systems.

Some CPU features require specific CPUID levels to be available in
order to function, as they contain information about the operation of
a specific feature.  However, some BIOSes and virtualization software
provide the ability to mask CPUID levels in order to support legacy
operating systems.  We try to enable such CPUID levels when we know
how to do it, but for the remaining cases, filter out such CPU
features when there is no way for us to support them.

Do this in one place, in the CPUID code, with a table-driven approach.

      x86: handle PAT more like other CPU features · 75a04811
      由 H. Peter Anvin 提交于 
      Impact: Cleanup

When PAT was originally introduced, it was handled specially for a few
reasons:

- PAT bugs are hard to track down, so we wanted to maintain a
  whitelist of CPUs.
- The i386 and x86-64 CPUID code was not yet unified.

Both of these are now obsolete, so handle PAT like any other features,
including ordinary feature blacklisting due to known bugs.

      x86: signal: use {get|put}_user_try and catch · 98e3d45e

      Impact: use new framework

Use {get|put}_user_try, catch, and _ex in arch/x86/kernel/signal.c.

Note: this patch contains "WARNING: line over 80 characters", because when
introducing new block I insert an indent to avoid mistakes by edit.
