The only fabrics target that supports metadata handling through the
separate integrity buffer is RDMA. It is currently usable only if the
size is 8B per block and formatted for protection information. If an
rdma target were to export a namespace with a different format (ex:
4k+64B), the driver will not be able to submit valid read/write commands
for that namespace.
Suppress setting the metadata feature in the namespace so that the
gendisk capacity will be set to 0. This will prevent read/write access
through the block stack, but will continue to allow ioctl passthrough
commands.

Commit 89b3d6e60550 ("nvme: simplify the compat ioctl handling") removed
the initialization of compat_ioctl from the nvme block_device_operations
structures.
Presumably the expectation was that 32-bit ioctls would be directed
through the regular handler but this is not the case: failing to assign
.compat_ioctl actually means that the compat case is disabled entirely,
and any attempt to submit nvme ioctls from 32-bit userspace fails
outright with -ENOTTY.
For example:
% smartctl -x /dev/nvme0n1

Do not record a pointer to a VMA outside of the mmap_lock for later use.
This is unsafe and there are a number of failure paths *after* the
recorded VMA pointer may be freed during setup. There is no callback to
the driver to clear the saved pointer from generic mm code. Furthermore,
the VMA pointer may become stale if any number of VMA operations end up
freeing the VMA so saving it was fragile to being with.
Instead, change the binder_alloc struct to record the start address of the
VMA and use vma_lookup() to get the vma when needed. Add lockdep
mmap_lock checks on updates to the vma pointer to ensure the lock is held
and depend on that lock for synchronization of readers and writers - which
was already the case anyways, so the smp_wmb()/smp_rmb() was not
necessary.

KVM emulates UMIP for both L1 and L2, and so should enumerate that L2 is

break nVMX, as KVM does set/clear the bit in CR4_FIXED1 in response to a
guest CPUID update, i.e. KVM will correctly (dis)allow nested VM-Entry

enumerate the bit as being allowed from time zero, e.g. userspace will

since it requires the new key portion provided by the mw consumer to be
different than the previous key portion. This is not required by the

[ Upstream commit e3c8d33e0d62175c31ca7ab7ab01b18f0b6318d3 ]
The type atomic_long_t can have size 4 or 8 bytes, depending on
CONFIG_64BIT; it's only content, the field 'counter', is either an
int or a s64 value.
Current code incorrectly uses the fixed size utils.read_u64() to
read the field 'counter' inside atomic_long_t.
On 32 bits architectures reading the last element 'tail_id' of the
struct prb_desc_ring:
struct prb_desc_ring {
...
atomic_long_t tail_id;
};
causes the utils.read_u64() to access outside the boundary of the
struct and the gdb command 'lx-dmesg' exits with error:
Python Exception <class 'IndexError'>: index out of range
Error occurred in Python: index out of range
Query the really used atomic_long_t counter type size.

For the gdb command lx-dmesg, the entire descriptor, info, and text
data regions are read into memory before printing any records. For
large kernel log buffers, this not only causes a huge delay before
seeing any records, but it may also lead to python errors of too
much memory allocation.
Rather than reading in all these regions in advance, read them as
needed and only read the regions for the particular record that is
being printed.
The gdb macro "dmesg" in Documentation/admin-guide/kdump/gdbmacros.txt
already prints out the kernel log buffer like this.

We should use of_node_get() when a new reference of device_node
is created. It is noted that the old reference stored in
'mm_gc->gc.of_node' should also be decreased.
This patch is based on the fact that there is a call site in function
'qe_add_gpiochips()' of src file 'drivers\soc\fsl\qe\gpio.c'. In this
function, of_mm_gpiochip_add_data() is contained in an iteration of
for_each_compatible_node() which will automatically increase and
decrease the refcount. So we need additional of_node_get() for the
reference escape in of_mm_gpiochip_add_data().
