The ARMv8 architecture allows execute-only user permissions by clearing
the PTE_UXN and PTE_USER bits. The kernel, however, can still access
such page, so execute-only page permission does not protect against
read(2)/write(2) etc. accesses. Systems requiring such protection must
implement/enable features like SECCOMP.

This patch changes the arm64 __P100 and __S100 protection_map[] macros
to the new __PAGE_EXECONLY attributes. A side effect is that
pte_valid_user() no longer triggers for __PAGE_EXECONLY since PTE_USER
isn't set. To work around this, the check is done on the PTE_NG bit via
the pte_valid_ng() macro. VM_READ is also checked now for page faults.

   - vexpress platform clocks initialisation moved earlier following the

   - Default DMA ops changed to non-coherent to preserve compatibility
     with 32-bit ARM DT files.  The "dma-coherent" property can be used

Following arm64 commit bc3ee18a (arm64: init: Move of_clk_init to
time_init()), vexpress_osc_of_setup() is called via of_clk_init() long

adds an explicit call to vexpress_sysreg_of_early_init() in vexpress

Commit d57c33c5 (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.

More recently, commit bf4b558e (arm64: add early_ioremap support)
converted the arm64 earlyprintk to use set_fixmap_io. A side effect of
this conversion is that my virtual machines have stopped booting when
I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel.

Turns out that the new earlyprintk code doesn't care at all about
sub-page offsets, and just assumes that the earlyprintk device will
be page-aligned. Obviously, that doesn't play well with the above example.

Further investigation shows that set_fixmap_io uses __set_fixmap instead
of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that
uses the latter, and to remove the superflous call to fix_to_virt
(which only returns the value that set_fixmap_io has already given us).

With this applied, my VMs are back in business. Tested on a Cortex-A57
platform with kvmtool as platform emulation.

Now these tests get run under different config options, and one of
those options is CONFIG_PROVE_RCU, which checks under lockdep that
the rcu locking primitives are being used correctly. This triggered

 "A bunch of regression fixes this time.  They fix two regressions in

  ACPI EC driver, four cpufreq driver regressions and an unrelated bug
  in one of the drivers.  The regressions are recent or introduced in
  3.14.

  Specifics:

   - There are two bugs in the ACPI PNP core that cause errors to be
     returned if optional ACPI methods are not present.  After an ACPI
     core change made in 3.14 one of those errors leads to serial port
     suspend failures on some systems.  Fix from Rafael J Wysocki.

   - A recently added PNP quirk related to Intel chipsets intorduced a
     build error in unusual configurations (PNP without PCI).  Fix from
     Bjorn Helgaas.

   - An ACPI EC workaround related to system suspend on Samsung machines
     added in 3.14 introduced a race causing some valid EC events to be
     discarded.  Fix from Kieran Clancy.

   - The acpi-cpufreq driver fails to load on some systems after a 3.14
     commit related to APIC ID parsing that overlooked one corner case.
     Fix from Lan Tianyu.

   - Fix for a recently introduced build problem in the ppc-corenet
     cpufreq driver from Tim Gardner.

   - A recent cpufreq core change to ensure serialization of frequency
     transitions for drivers with a ->target_index() callback overlooked
     the fact that some of those drivers had been doing operations
     introduced by it into the core already by themselves.  That
     resulted in a mess in which the core and the drivers try to do the
     same thing and block each other which leads to deadlocks.  Fixes

There are only a couple of architectures that override _STK_LIM_MAX to
a non-infinity value. This changes the stack allocation semantics in
subtle ways. For example, GNU make changes its stack allocation to the
hard maximum defined by _STK_LIM_MAX. As a results, threads executed
by processes running under make are allocated a stack size of
_STK_LIM_MAX rather than a sensible default value. This causes various
thread stress tests to fail when they can't muster more than about 50
threads.

The attached change implements the default behavior used by the
majority of architectures.
