UBUNTU: [Packaging] remove circular dep between modules and image
49b3060 
Currently we have circular dependencies between linux-image and
linux-modules/linux-modules-extra packages. This is redundant, and
harmful when additional types of linux-images are provided
(i.e. kernel.efi).

Break the circular dependency by only keeping linux-image ->
linux-modules dep, remove linux-modules -> linux-image dep, remove
linux-modules-extra -> linux-image dep, add linux-modules-extra ->
linux-modules dep.

UBUNTU: SAUCE: TDX: Work around the segfault issue in glibc 2.35 in U…
eec6ba4 
…buntu 22.04.

BugLink: https://bugs.launchpad.net/bugs/2003714

glibc 2.34/2.35 (and 2.36?) had a bug (2.32 is good):
See https://sourceware.org/bugzilla/show_bug.cgi?id=28784

The bug has been fixed in upstream glibc:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=c242fcce06e3102ca663b2f992611d0bda4f2668

However, it looks like a lot of distros haven't picked up the fix yet,
e.g. Ubuntu 22.04/22.10/23.04's glibc need pick up the glibc fix (c242fcce06e3102ca663b2f992611d0bda4f2668).
RHEL 9's glibc needs the glibc fix as well.

Before the glibc packages in the distros are fixed, we can use this
kernel side workaround patch for now. The workaround is from Intel.
See the below for the rationale:

x86/tdx: Virtualize CPUID leaf 0x2
CPUID leaf 0x2 provides cache and TLB information. In TDX guest access
to the leaf causes #VE.

Current implementation returns all zero, but it confuses some users:
some recent versions of GLIBC hit segfaults. It is a GLIBC bug, but it is
also a user-visible regression comparing to non-TDX environment.

Kernel can generate a sensible response to the #VE to work around the
glibc segfault for now.

The leaf is obsolete. There are leafs that provides the same
information in a structured form. See leaf 0x4 on cache info and
leaf 0x18 on TLB info.

Generate a response that indicates that CPUID leaf 0x4 and 0x18 have to
be used instead.

drm/msm: Fix shrinker deadlock

commit 3392291fc509d8ad6e4ad90f15b0a193f721cbc9 upstream.

With PROVE_LOCKING on an Snapdragon X1 and VM reclaim pressure, we see:

   but task is already holding lock:

   which lock already depends on the new lock.

kswapd0 holding fs_reclaim calls the MSM shrinker, which calls
dma_resv_lock. This in turn acquires fs_reclaim.

Fix this deadlock by using dma_resv_trylock() instead, dropping the
subsequently unused passed wait-wound lock 'ticket'.
