[PATCH] libata: Apply NOLPM quirk to Crucial MX100 512GB SSDs

by Hans de Goede

Various people have reported the Crucial MX100 512GB model not working with LPM set to min_power. I've now received a report that it also does not work with the new med_power_with_dipm level. It does work with medium_power, but that has no measurable power-savings and given the amount of people being bitten by the other levels not working, this commit just disables LPM altogether. Note all reporters of this have either the 512GB model (max capacity), or are not specifying their SSD's size. So for now this quirk assumes this is a problem with the 512GB model only.

[RESEND v2] mm: don't defer struct page initialization for Xen pv guests

by Juergen Gross

Commit f7f99100d8d95dbcf09e0216a143211e79418b9f ("mm: stop zeroing memory during allocation in vmemmap") broke Xen pv domains in some configurations, as the "Pinned" information in struct page of early page tables could get lost. This will lead to the kernel trying to write directly into the page tables instead of asking the hypervisor to do so. The result is a crash like the following: [ 0.004000] BUG: unable to handle kernel paging request at ffff8801ead19008 [ 0.004000] IP: xen_set_pud+0x4e/0xd0 [ 0.004000] PGD 1c0a067 P4D 1c0a067 PUD 23a0067 PMD 1e9de0067 PTE 80100001ead19065 [ 0.004000] Oops: 0003 [#1] PREEMPT SMP [ 0.004000] Modules linked in: [ 0.004000] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.14.0-default+ #271 [ 0.004000] Hardware name: Dell Inc.

I missed that when I wrote the new changelog text for this old patch of mine. It also means I should rebase the patch so it applies on mainline, as I still want PROFILE_ALL_BRANCHES to be disabled in COMPILE_TEST kernels for the build speed aspect. Greg, could you add the 68e76e034b6b1 commit to 4.14-stable and 4.15-stable in the meantime? Arnd
