patch "USB: usb-storage: Add new IDs to ums-realtek" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: usb-storage: Add new IDs to ums-realtek to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From a84a1bcc992f0545a51d2e120b8ca2ef20e2ea97 Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng <kai.heng.feng(a)canonical.com> Date: Fri, 23 Nov 2018 08:42:19 +0000 Subject: USB: usb-storage: Add new IDs to ums-realtek There are two new Realtek card readers require ums-realtek to work correctly.

FAILED: patch "[PATCH] x86/mm: Move LDT remap out of KASLR region on 5-level paging" failed to apply to 4.18-stable tree

The patch below does not apply to the 4.18-stable tree.

Shutemov" <kirill.shutemov(a)linux.intel.com> Date: Fri, 26 Oct 2018 15:28:54 +0300 Subject: [PATCH] x86/mm: Move LDT remap out of KASLR region on 5-level paging On 5-level paging the LDT remap area is placed in the middle of the KASLR randomization region and it can overlap with the direct mapping, the vmalloc or the vmap area. The LDT mapping is per mm, so it cannot be moved into the P4D page table next to the CPU_ENTRY_AREA without complicating PGD table allocation for 5-level paging. The 4 PGD slot gap just before the direct mapping is reserved for hypervisors, so it cannot be used. Move the direct mapping one slot deeper and use the resulting gap for the LDT remap area. The resulting layout is the same for 4 and 5 level paging. [ tglx: Massaged changelog ] Fixes: f55f0501cbf6 ("x86/pti: Put the LDT in its own PGD if PTI is on") Signed-off-by: Kirill A.
