Memory bandwidth allocation requires different information than cache
allocation.

To avoid a lump of data in struct rdt_resource, move all cache related
information into a seperate structure and add that to struct rdt_resource.

Sanitize the data types while at it.

Lot of data structures and functions are named after cache specific
resources(named after cbm, cache etc). In many cases other non cache
resources may need to share the same data structures/functions.

Generalize such naming to prepare to add more resources like memory
bandwidth.

The schemata lock is released before freeing the resource's temporary
tmp_cbms allocation. That's racy versus another write which allocates and
uses new temporary storage, resulting in memory leaks, freeing in use
memory, double a free or any combination of those.

Move the unlock after the release code.

The resource control filesystem provides only a bitmask based cpus file for
assigning CPUs to a resource group. That's cumbersome with large cpumasks
and non-intuitive when modifying the file from the command line.

Range based cpu lists are commonly used along with bitmask based cpu files
in various subsystems throughout the kernel.

Add 'cpus_list' file which is CPU range based.

  # cd /sys/fs/resctrl/
  # echo 1-10 > krava/cpus_list
  # cat krava/cpus_list

vdso_enabled can be set to arbitrary integer values via the kernel command
line 'vdso32=' parameter or via 'sysctl abi.vsyscall32'.

load_vdso32() only maps VDSO if vdso_enabled == 1, but ARCH_DLINFO_IA32
merily checks for vdso_enabled != 0. As a consequence the AT_SYSINFO_EHDR
auxiliary vector for the VDSO_ENTRY is emitted with a NULL pointer which
causes a segfault when the application tries to use the VDSO.

Restrict the valid arguments on the command line and the sysctl to 0 and 1.

We should be detaching the MMU before destroying the address

adreno_gpu_cleanup() because it needs access to structs
in adreno_gpu.c.  Plus it is better symmetry to have
the attach and detach at the same code level.

A recent commit introduces a bug in dsi_mgr_phy_enable. In the non
dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right
since master and slave DSI exist only in dual DSI mode. For the normal
mode of operation, we should simply reset the PHY of the DSI device
(i.e. msm_dsi) corresponding to the current bridge.

Usage of the wrong DSI pointer also resulted in a static checker
warning. That too is resolved with this fix.

  While fixing the memcpy bug we noticed some other issues with our
  get_user() and put_user() functions, e.g. nested faults may return
  wrong data. This is now fixed by a common fixup handler for
  get_user/put_user in the exception handler which additionally makes
  generated code smaller and faster.

  The third patch is a trivial one-line fix for a patch which went in
  during 4.11-rc and which avoids stalled CPU warnings after power
  shutdown (for parisc machines which can't plug power off themselves).

  Due to the rewrite of pa_memcpy() into assembly this patch got bigger
