Public bug reported:

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The v4.18.2 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

       The following patches from the v4.18.2 stable release shall be
applied:

x86/l1tf: Fix build error seen if CONFIG_KVM_INTEL is disabled
x86: i8259: Add missing include file
x86/hyper-v: Check for VP_INVAL in hyperv_flush_tlb_others()
x86/platform/UV: Mark memblock related init code and data correctly
x86/mm/pti: Clear Global bit more aggressively
xen/pv: Call get_cpu_address_sizes to set x86_virt/phys_bits
x86/mm: Disable ioremap free page handling on x86-PAE
kbuild: verify that $DEPMOD is installed
crypto: ccree - fix finup
crypto: ccree - fix iv handling
crypto: ccp - Check for NULL PSP pointer at module unload
crypto: ccp - Fix command completion detection race
crypto: x86/sha256-mb - fix digest copy in sha256_mb_mgr_get_comp_job_avx2()
crypto: vmac - require a block cipher with 128-bit block size
crypto: vmac - separate tfm and request context
crypto: blkcipher - fix crash flushing dcache in error path
crypto: ablkcipher - fix crash flushing dcache in error path
crypto: skcipher - fix aligning block size in skcipher_copy_iv()
crypto: skcipher - fix crash flushing dcache in error path
Bluetooth: hidp: buffer overflow in hidp_process_report
ioremap: Update pgtable free interfaces with addr
x86/mm: Add TLB purge to free pmd/pte page interfaces
