Fixes for v6.0

- Fix for inconsistent indenting in function msm_dsi_dphy_timing_calc_v3.
  This fixes a smatch warning reported by kbot
- Fix to make eDP the first connector in the connected list. This was
  mainly done to address a screen corruption issue we were seeing on
  sc7280 boards which have eDP as the primary display. The corruption
  itself is from usermode but we decided to fix it this way because
  things work correct with the primary display as the first one for
  usermode
- Fix to populate intf_cfg correctly before calling reset_intf_cfg().
  Without this, the display pipeline is not torn down correctly for

We have to copy only selected fields from the original resource.
Because a PCI device will be removed immediately after getting
its resources, we may not use any allocated data, hence we may
not copy any pointers.

Consider the following scenario:

  1/ a caller of p2sb_bar() gets the resource;

  2/ the resource has been copied by platform_device_add_data()
     in order to create a platform device;

  3/ the platform device creation will call for the device driver's
     ->probe() as soon as a match found;

  4/ the ->probe() takes given resources (see 2/) and tries to
     access one of its field, i.e. 'name', in the
     __devm_ioremap_resource() to create a pretty looking output;

  5/ but the 'name' is a dangling pointer because p2sb_bar()
     removed a PCI device, which 'name' had been copied to
     the caller's memory.

  6/ UAF (Use-After-Free) as a result.

Kudos to Mika for the initial analisys of the issue.

In the case of firmware-upload, an instance of struct fw_upload is

In the following code within firmware_upload_unregister(), the call to
device_unregister() could result in the dev_release function freeing the
fw_upload_priv structure before it is dereferenced for the call to
module_put(). This bug was found by the kernel test robot using
CONFIG_KASAN while running the firmware selftests.

  device_unregister(&fw_sysfs->dev);
  module_put(fw_upload_priv->module);

The problem is fixed by copying fw_upload_priv->module to a local variable
for use when calling device_unregister().

Syzbot reported a couple issues introduced by commit 44e602b4
("binder_alloc: add missing mmap_lock calls when using the VMA"), in
which we attempt to acquire the mmap_lock when alloc->vma_vm_mm has not
been initialized yet.

This can happen if a binder_proc receives a transaction without having
previously called mmap() to setup the binder_proc->alloc space in [1].
Also, a similar issue occurs via binder_alloc_print_pages() when we try
to dump the debugfs binder stats file in [2].

Fix these issues by setting up alloc->vma_vm_mm pointer during open()
and caching directly from current->mm. This guarantees we have a valid
reference to take the mmap_lock during scenarios described above.

Both __device_attach_driver() and __driver_attach() check the return
code of the bus_type.match() function to see if the device needs to be
added to the deferred probe list. After adding the device to the list,
the logic attempts to bind the device to the driver anyway, as if the
device had matched with the driver, which is not correct.

If __device_attach_driver() detects that the device in question is not
ready to match with a driver on the bus, then it doesn't make sense for
the device to attempt to bind with the current driver or continue
attempting to match with any of the other drivers on the bus. So, update
the logic in __device_attach_driver() to reflect this.

If __driver_attach() detects that a driver tried to match with a device
that is not ready to match yet, then the driver should not attempt to bind
with the device. However, the driver can still attempt to match and bind
with other devices on the bus, as drivers can be bound to multiple
devices. So, update the logic in __driver_attach() to reflect this.

- All the devices can be deleted before MLXREG_LC_POWERED flag is cleared.

- Add lock() / unlock() at the beginning / end of

  mlxreg_lc_power_on_off() and mlxreg_lc_enable_disable()

2 keymap fixes for the Acer Aspire One AOD270 and the same hardware
rebranded as Packard Bell Dot SC:

1. The F2 key is marked with a big '?' symbol on the Packard Bell Dot SC,
this sends WMID_HOTKEY_EVENTs with a scancode of 0x27 add a mapping
for this.

2. Scancode 0x61 is KEY_SWITCHVIDEOMODE. Usually this is a duplicate
input event with the "Video Bus" input device events. But on these devices
the "Video Bus" does not send events for this key. Map 0x61 to KEY_UNKNOWN
instead of using KE_IGNORE so that udev/hwdb can override it on these devs.

The logic that conditionally allocates one additional page at each
swapper page table level if KASLR is enabled is also applied to the
initial ID map, now that we have started using the same set of macros
to allocate the space for it.

However, the placement of the kernel in physical memory might result in
additional pages being needed at any level, even if KASLR is disabled in
the build. So account for this in the computation.

Even non-KASLR kernels can be built as relocatable, to work around
broken bootloaders that violate the rules regarding physical placement
of the kernel image - in this case, the physical offset modulo 2 MiB is
used as the KASLR offset, and all absolute symbol references are fixed
up in the usual way. This workaround is enabled by default.

CONFIG_RELOCATABLE can also be disabled entirely, in which case the
relocation code and the code that captures the offset are omitted from
the build. However, since commit aacd149b ("arm64: head: avoid
relocating the kernel twice for KASLR"), this code got out of sync, and
we still add the offset to the kernel virtual address before populating
the page tables even though we never capture it. This means we add a
bogus value instead, breaking the boot entirely.

mm/slab_common: Deleting kobject in kmem_cache_destroy() without holding slab_mutex/cpu_hotplug_lock

A circular locking problem is reported by lockdep due to the following
circular locking dependency.

  +--> cpu_hotplug_lock --> slab_mutex --> kn->active --+
  |                                                     |
  +-----------------------------------------------------+

The forward cpu_hotplug_lock ==> slab_mutex ==> kn->active dependency
happens in

  kmem_cache_destroy():	cpus_read_lock(); mutex_lock(&slab_mutex);
  ==> sysfs_slab_unlink()
      ==> kobject_del()
          ==> kernfs_remove()
	      ==> __kernfs_remove()
	          ==> kernfs_drain(): rwsem_acquire(&kn->dep_map, ...);

The backward kn->active ==> cpu_hotplug_lock dependency happens in

  kernfs_fop_write_iter(): kernfs_get_active();
  ==> slab_attr_store()
      ==> cpu_partial_store()
          ==> flush_all(): cpus_read_lock()

One way to break this circular locking chain is to avoid holding
cpu_hotplug_lock and slab_mutex while deleting the kobject in
sysfs_slab_unlink() which should be equivalent to doing a write_lock
and write_unlock pair of the kn->active virtual lock.

Since the kobject structures are not protected by slab_mutex or the
cpu_hotplug_lock, we can certainly release those locks before doing
the delete operation.

Move sysfs_slab_unlink() and sysfs_slab_release() to the newly
created kmem_cache_release() and call it outside the slab_mutex &
cpu_hotplug_lock critical sections. There will be a slight delay
in the deletion of sysfs files if kmem_cache_release() is called
indirectly from a work function.
