[Kernel-packages] [Bug 1772617] Re: fix inverted boolean flag in arch_add_memory, reverts back to original behaviour
Artful is now EOL, closing bug ** Changed in: linux (Ubuntu) Status: In Progress => Won't Fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1772617 Title: fix inverted boolean flag in arch_add_memory, reverts back to original behaviour Status in linux package in Ubuntu: Won't Fix Bug description: == SRU Justification, ARTFUL == Bug fix #1761104 incorrectly inverted the flag in the call to arch_add_memory, it should be true instead of false. == Fix == Fix partial backport from bug #1747069, remove can_online_high_movable and fix the incorrectly set boolean argument to arch_add_memory(). NVIDIA are reported that this is was incorrectly flipped in the last SRU to fix their driver support on powerpc. == Testing == run ADT memory hotplug test, should not regress this. Without the fix, the nvidia driver on powerpc will not work. With the fix it loads and works. == Regression Potential == This fixes a regression in the original fix and hence the regression potential is the same as the previously SRU'd bug fix for #1747069, namely: "Reverting this commit does remove some functionality, however this does not regress the kernel compared to previous releases and having a working reliable memory hotplug is the preferred option. This fix does touch some memory hotplug, so there is a risk that this may break this functionality that is not covered by the kernel regression testing."
