Now, I've had gcc 5.5.0 installed on 2 hosts since last saturday, and a 4.4.17-1 built with the new gcc running on 2 systems since then, and it seems to behave... but YMMV...

Depends on: (none) => 22525

And a Meltdown / Spectre status check with this kernel (and the new gcc)

on an Intel system:

CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Mitigated according to the /sys interface:  YES  (kernel confirms that the mitigation is active)
* Kernel has array_index_mask_nospec:  YES  (1 occurence(s) found of 64 bits array_index_mask_nospec())
> STATUS:  NOT VULNERABLE  (Mitigation: __user pointer sanitization)

CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* Mitigated according to the /sys interface:  YES  (kernel confirms that the mitigation is active)
* Mitigation 1
  * Kernel is compiled with IBRS/IBPB support:  NO 
  * Currently enabled features
    * IBRS enabled for Kernel space:  NO 
    * IBRS enabled for User space:  NO 
    * IBPB enabled:  NO 
* Mitigation 2
  * Kernel compiled with retpoline option:  YES 
  * Kernel compiled with a retpoline-aware compiler:  YES  (kernel reports full retpoline compilation)
  * Retpoline enabled:  NO 
> STATUS:  NOT VULNERABLE  (Mitigation: Full generic retpoline)

CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'
* Mitigated according to the /sys interface:  YES  (kernel confirms that the mitigation is active)
* Kernel supports Page Table Isolation (PTI):  YES 
* PTI enabled and active:  YES 
* Running as a Xen PV DomU:  NO 
> STATUS:  NOT VULNERABLE  (Mitigation: PTI)



and on an Amd system:

CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Mitigated according to the /sys interface:  YES  (kernel confirms that the mitigation is active)
> STATUS:  NOT VULNERABLE  (Mitigation: __user pointer sanitization)

CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* Mitigated according to the /sys interface:  YES  (kernel confirms that the mitigation is active)
* Mitigation 1
  * Kernel is compiled with IBRS/IBPB support:  NO 
  * Currently enabled features
    * IBRS enabled for Kernel space:  NO 
    * IBRS enabled for User space:  NO 
    * IBPB enabled:  NO 
* Mitigation 2
  * Kernel compiled with retpoline option:  YES 
  * Kernel compiled with a retpoline-aware compiler:  YES  (kernel reports full retpoline compilation)
  * Retpoline enabled:  NO 
> STATUS:  NOT VULNERABLE  (Mitigation: Full AMD retpoline)

CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'
* Mitigated according to the /sys interface:  YES  (kernel confirms that your CPU is unaffected)
* Kernel supports Page Table Isolation (PTI):  YES 
* PTI enabled and active:  NO 
* Running as a Xen PV DomU:  NO 
> STATUS:  NOT VULNERABLE  (your CPU vendor reported your CPU model as not vulnerable)



so 3/3 atatus: NOT_VULNERABLE

Updated gcc and then the kernel packages.
dkms builds looked successful including virtualbox modules.
Clean reboot.

OK, final 4.14.18 is now out wit some added fixes ready to be fully tested, validated and pushed out...

One 64-bit Plasma install, with virtualbox, using the desktop kernel. One 32-bit Plasma install, without virtualbox, with both desktop and server kernels installed. 

64-bit: Everything looks good, including virtualbox. Windows XP guest updating antivirus as I type this.

32-bit: Everything looks good, except that Bug #22528, suspend/resume, is still valid.
