      Revert "ARM: rockchip: fix undefined instruction of reset_ctrl_regs" · 3f937cf3
      由 Heiko Stuebner 提交于 
      This reverts commit b403125d.

As reported by Chris, both commits
        b403125d "ARM: rockchip: fix undefined instruction of reset_ctrl_regs"
        0ea001d3 "ARM: rockchip: disable dapswjdp during suspend"
actually fix the same issue and b403125d is the older one, which got
superseded by 0ea001d3. Therefore revert the obsolete one again.

      ARM: EXYNOS: Fix dereference of ERR_PTR returned by of_genpd_get_from_provider · 0b7dc0ff
      由 Krzysztof Kozlowski 提交于 
      ERR_PTR was dereferenced during sub domain parsing, if parent domain
could not be obtained (because of invalid phandle or deferred
registration of parent domain).

The Exynos power domain code checked whether
of_genpd_get_from_provider() returned NULL and in that case it skipped
that power domain node. However this function returns ERR_PTR or valid
pointer, not NULL.

      MIPS: Fix a preemption issue with thread's FPU defaults · 03dce595
      由 Maciej W. Rozycki 提交于 
      Fix "BUG: using smp_processor_id() in preemptible" reported in accesses
to thread's FPU defaults: the value to initialise FSCR to at program
startup, the FCSR r/w mask and the contents of FIR in full FPU
emulation, removing a regression introduced with 9b26616c [MIPS: Respect
the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR
feature flags for full emulation].

Use `boot_cpu_data' to obtain the data from, following the approach that
`cpu_has_*' macros take and avoiding the call to `smp_processor_id' made
in the reference to `current_cpu_data'.  The contents of FSCR have to be
consistent across processors in an SMP system, the settings there must
not change as a thread is migrated across processors.  And the contents
of FIR are guaranteed to be consistent in FPU emulation, by definition.

      parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards architectures · d045c77c
      由 Helge Deller 提交于 
      On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y,
currently parisc and metag only) stack randomization sometimes leads to crashes
when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB
by default if not defined in arch-specific headers).

The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the
additional space needed for the stack randomization (as defined by the value of
STACK_RND_MASK) was not taken into account yet and as such, when the stack
randomization code added a random offset to the stack start, the stack
effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK)
which then sometimes leads to out-of-stack situations and crashes.

This patch fixes it by adding the maximum possible amount of memory (based on
STACK_RND_MASK) which theoretically could be added by the stack randomization
code to the initial stack size. That way, the user-defined stack size is always
guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK).

This bug is currently not visible on the metag architecture, because on metag
STACK_RND_MASK is defined to 0 which effectively disables stack randomization.

The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP"
section, so it does not affect other platformws beside those where the
stack grows upwards (parisc and metag).

So Suspend-to-RAM and Suspend-to-idle is failing on Exynos5800 Peach Pi

      MIPS: fix FP mode selection in lieu of .MIPS.abiflags data · 620b1550
      由 Paul Burton 提交于 
      Commit 46490b57 ("MIPS: kernel: elf: Improve the overall ABI and FPU
mode checks") reworked the ELF FP ABI mode selection logic, but when
CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
which have no PT_MIPS_ABIFLAGS program header & associated
.MIPS.abiflags section.

A default mode is selected based upon whether the ELF contains MIPS32 or
MIPS64 code, but that selection is made in arch_elf_pt_proc.
arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
found. If one is not found then arch_elf_pt_proc is never called, and no
default overall_fp_mode value is selected. When arch_check_elf is
called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
prog_req & interp_req being set to none_req. none_req matches none of
the conditions for mode selection at the end of arch_check_elf, so
overall_fp_mode is left untouched. Finally once mips_set_personality_fp
is called the BUG() in the default case is then hit & the kernel likely
panics.

Fix this by moving the selection of a default overall mode to the start
of arch_check_elf, which runs once per ELF executed regardless of
whether it has a PT_MIPS_ABIFLAGS program header.

      The clock generator in IOFPGA generates the two source clocks: 32kHz and

The SP810 System Controller selects 32kHz or 1MHz as the sources for
TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but
the maximum of "refclk" and "timclk" is chosen by the SP810 driver.

This patch adds support for SP810 system controller and also fixes the
SP804 timer clock frequency.

However the SP804 driver needs to be enabled on ARM64 to test this,
which requires SP804 driver to be moved out of arch/arm.

      ARM: OMAP2+: Remove bogus struct clk comparison for timer clock · b0897972
      由 Tony Lindgren 提交于 
      With recent changes to use determine_rate, the comparison of two
clocks won't work without clk_is_match that does __clk_get_hw
on the clocks first.

As we've been unconditionally already calling clk_set_parent
already because of the bogus comparison, let's just remove the
check as suggested by Stephen Boyd <sboyd@codeaurora.org>.
