      sched/cpufreq: Initialize sg_cpu->flags to 0 · 6257e704
      Viresh Kumar authored 
      Initializing sg_cpu->flags to SCHED_CPUFREQ_RT has no obvious benefit.
The flags field wouldn't be used until the utilization update handler is
called for the first time, and once that is called we will overwrite
flags anyway.

Initialize it to 0.

      sched/fair: Consider RT/IRQ pressure in capacity_spare_wake() · f453ae22
      Joel Fernandes authored 
      capacity_spare_wake() in the slow path influences choice of idlest groups,
as we search for groups with maximum spare capacity. In scenarios where
RT pressure is high, a sub optimal group can be chosen and hurt
performance of the task being woken up.

Fix this by using capacity_of() instead of capacity_orig_of() in capacity_spare_wake().

Tests results from improvements with this change are below. More tests
were also done by myself and Matt Fleming to ensure no degradation in
different benchmarks.

1) Rohit ran barrier.c test (details below) with following improvements:
------------------------------------------------------------------------
This was Rohit's original use case for a patch he posted at [1] however
from his recent tests he showed my patch can replace his slow path
changes [1] and there's no need to selectively scan/skip CPUs in
find_idlest_group_cpu in the slow path to get the improvement he sees.

barrier.c (open_mp code) as a micro-benchmark. It does a number of
iterations and barrier sync at the end of each for loop.

Here barrier,c is running in along with ping on CPU 0 and 1 as:
'ping -l 10000 -q -s 10 -f hostX'

barrier.c can be found at:

      sched/fair: Use 'unsigned long' for utilization, consistently · f01415fd
      Patrick Bellasi authored 
      Utilization and capacity are tracked as 'unsigned long', however some
functions using them return an 'int' which is ultimately assigned back to
'unsigned long' variables.

Since there is not scope on using a different and signed type,
consolidate the signature of functions returning utilization to always
use the native type.

This change improves code consistency, and it also benefits
code paths where utilizations should be clamped by avoiding
further type conversions or ugly type casts.

      sched/core: Rework and clarify prepare_lock_switch() · 31cb1bc0
      rodrigosiqueira authored 
      The prepare_lock_switch() function has an unused parameter, and also the
function name was not descriptive. To improve readability and remove
the extra parameter, do the following changes:

* Move prepare_lock_switch() from kernel/sched/sched.h to
  kernel/sched/core.c, rename it to prepare_task(), and remove the
  unused parameter.

* Split the smp_store_release() out from finish_lock_switch() to a
  function named finish_task.

* Comments ajdustments.

      x86/tlb: Drop the _GPL from the cpu_tlbstate export · 1e547681
      Thomas Gleixner authored 
      The recent changes for PTI touch cpu_tlbstate from various tlb_flush
inlines. cpu_tlbstate is exported as GPL symbol, so this causes a
regression when building out of tree drivers for certain graphics cards.

Aside of that the export was wrong since it was introduced as it should
have been EXPORT_PER_CPU_SYMBOL_GPL().

Use the correct PER_CPU export and drop the _GPL to restore the previous
state which allows users to utilize the cards they payed for.

As always I'm really thrilled to make this kind of change to support the
#friends (or however the hot hashtag of today is spelled) from that closet
sauce graphics corp.

set_pte_vaddr is used to map the ds buffers into the cpu entry area, but
there are two problems with that:

 1) The resulting flush is not supposed to be called in preemptible context

 2) The cpu entry area is supposed to be per CPU, but the debug store
    buffers are mapped for all CPUs so these mappings need to be flushed
    globally.

Add the necessary preemption protection across the mapping code and flush
TLBs globally.

      x86/kaslr: Fix the vaddr_end mess · 1dddd251
      Thomas Gleixner authored 
      vaddr_end for KASLR is only documented in the KASLR code itself and is
adjusted depending on config options. So it's not surprising that a change
of the memory layout causes KASLR to have the wrong vaddr_end. This can map
arbitrary stuff into other areas causing hard to understand problems.

Remove the whole ifdef magic and define the start of the cpu_entry_area to
be the end of the KASLR vaddr range.

Add documentation to that effect.

      x86/mm: Set MODULES_END to 0xffffffffff000000 · f5a40711
      Andrey Ryabinin authored 
      Since f06bdd40 ("x86/mm: Adapt MODULES_END based on fixmap section size")
kasan_mem_to_shadow(MODULES_END) could be not aligned to a page boundary.

So passing page unaligned address to kasan_populate_zero_shadow() have two
possible effects:

1) It may leave one page hole in supposed to be populated area. After commit
  21506525 ("x86/kasan/64: Teach KASAN about the cpu_entry_area") that
  hole happens to be in the shadow covering fixmap area and leads to crash:

 BUG: unable to handle kernel paging request at fffffbffffe8ee04
 RIP: 0010:check_memory_region+0x5c/0x190

 Call Trace:
  <NMI>
  memcpy+0x1f/0x50
  ghes_copy_tofrom_phys+0xab/0x180
  ghes_read_estatus+0xfb/0x280

  default_do_nmi+0x57/0x110
  do_nmi+0xf8/0x150
  end_repeat_nmi+0x1a/0x1e

Note, the crash likely disappeared after commit 92a0f81d, which
changed kasan_populate_zero_shadow() call the way it was before
commit 21506525.

2) Attempt to load module near MODULES_END will fail, because
   __vmalloc_node_range() called from kasan_module_alloc() will hit the
   WARN_ON(!pte_none(*pte)) in the vmap_pte_range() and bail out with error.

To fix this we need to make kasan_mem_to_shadow(MODULES_END) page aligned
which means that MODULES_END should be 8*PAGE_SIZE aligned.

The whole point of commit f06bdd40 was to move MODULES_END down if
NR_CPUS is big, so the cpu_entry_area takes a lot of space.
But since 92a0f81d ("x86/cpu_entry_area: Move it out of the fixmap")
the cpu_entry_area is no longer in fixmap, so we could just set
MODULES_END to a fixed 8*PAGE_SIZE aligned address.

     got introduced when DTC started warning about some obvious
     mistakes. We still have some remaining warnings that probably may
     have to wait until 4.16 to get fixed while we try to figure out
     what the correct contents should be.

   - On Allwinner A64, Ethernet PHYs need a fix after a mistake in
     coordination between patches merged through multiple branches.

   - Various fixes for PMICs on allwinner based boards

   - Two fixes for ethernet link detection on some Renesas machines

   - Two stability fixes for rockchip based boards

  Aside from device-tree, two other areas got fixes for older problems:

   - For TI Davinci DM365, a couple of fixes were needed to repair the
     MMC DMA engine support, apparently this has been broken for a
     while.

   - One important fix for all Allwinner chips with the PMIC driver as a
     loadable module"
