Subject: x86: Handle legacy PIC interrupts on all the cpu's

Ingo Molnar reported that with the recent changes of not
statically blocking IRQ0_VECTOR..IRQ15_VECTOR's on all the
cpu's, broke an AMD platform (with Nvidia chipset) boot when
"noapic" boot option is used.

On this platform, legacy PIC interrupts are getting delivered to
all the cpu's instead of just the boot cpu. Thus not
initializing the vector to irq mapping for the legacy irq's
resulted in not handling certain interrupts causing boot hang.

Fix this by initializing the vector to irq mapping on all the
logical cpu's, if the legacy IRQ is handled by the legacy PIC.

Subject: x86: Fix placement of FIX_OHCI1394_BASE

Ever for 32-bit with sufficiently high NR_CPUS, and starting
with commit 789d03f584484af85dbdc64935270c8e45f36ef7 also for
64-bit, the statically allocated early fixmap page tables were
not covering FIX_OHCI1394_BASE, leading to a boot time crash
when "ohci1394_dma=early" was used. Despite this entry not being
a permanently used one, it needs to be moved into the permanent
range since it has to be close to FIX_DBGP_BASE and
FIX_EARLYCON_MEM_BASE.

Subject: powerpc/perf_events: Fix call-graph recording, add
 perf_arch_fetch_caller_regs

This implements a powerpc version of perf_arch_fetch_caller_regs
to get correct call-graphs.

It's implemented in assembly because that way we can be sure there isn't
a stack frame for perf_arch_fetch_caller_regs.  If it was in C, gcc might
or might not create a stack frame for it, which would affect the number
of levels we have to skip.

With this, we see results from perf record -e lock:lock_acquire like
this:

Subject: x86, amd: Restrict usage of c1e_idle()

Currently c1e_idle returns true for all CPUs greater than or equal to
family 0xf model 0x40. This covers too many CPUs.

Meanwhile a respective erratum for the underlying problem was filed
(#400). This patch adds the logic to check whether erratum #400
applies to a given CPU.
Especially for CPUs where SMI/HW triggered C1e is not supported,
c1e_idle() doesn't need to be used. We can check this by looking at
the respective OSVW bit for erratum #400.

Subject: [ARM] locomo: fix SPI register offset

The locomo spi registers are all defined in locomo.h as offsets
from the first spi register LOCOMO_SPI (0x60), which is itself
an offset from the locomo base address.  To correctly access
these registers LOCOMO_SPI must always be included in the
address calculation.

There are two places in locomo.c where this is not done.  The
first one, in locomo_suspend, actually results in a write to
LOCOMO_ST instead of LOCOMO_SPICT.  The second is in __locomo_probe
and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE.

Fix these by including LOCOMO_SPI in the calculation.

Subject: [ARM] locomo: fix unpaired spin_lock_irqsave

The function locomo_m62332_senddata sends a three byte i2c message to
a M62332 DAC. This entire function is guarded with a spin_lock_irqsave
at the start of the function and a spin_unlock_irqrestore at the end.

As each byte is transferred, the i2c ACK from the DAC is checked.
Currently, if the ACK is missing the function simply returns without
the unlock. It also leaves the i2c bus in an invalid state since the
last byte transferred did not have a "stop" condition and leave the
bus idle.

Fix this by adding an exit path using goto.

Subject: x86 / perf: Fix suspend to RAM on HP nx6325

Commit 3f6da3905398826d85731247e7fbcf53400c18bd
(perf: Rework and fix the arch CPU-hotplug hooks) broke suspend to
RAM on my HP nx6325 (and most likely on other AMD-based boxes too)
by allowing amd_pmu_cpu_offline() to be executed for CPUs that are
going offline as part of the suspend process.  The problem is that
cpuhw->amd_nb may be NULL already, so the function should make sure
it's not NULL before accessing the object pointed to by it.

Subject: sh: Replace unsafe manipulation of MMUCR

Setting the TI in MMUCR causes all the TLB bits in MMUCR to be
cleared. Unfortunately, the TLB wired bits are also cleared when setting
the TI bit, causing any wired TLB entries to become unwired.

Use local_flush_tlb_all() which implements TLB flushing in a safer
manner by using the memory-mapped TLB registers. As each CPU has its own
PMB the modifications in pmb_init() only affect the local CPU, so only
flush the local CPU's TLB.

Subject: [S390] zcore: CPU registers are not saved under LPAR

To save the registers for all CPUs a sigp "store status" is done that
stores the registers to address absolute zero. To access storage at
absolute zero, normally the address of the prefix register of the
accessing CPU has to be used. This does not work when large pages are
active (currently only under LPAR). In order to fix that problem,
instead of memcpy memcpy_real is used, which switches to real mode
where prefixing works.

Subject: [S390] smp: fix lowcore allocation

The intermediate lowcore for CONFIG_SMP is allocated using a call to
__alloc_bootmem() with a goal of 0. That however doesn't guarantee that
the allocated piece of memory is below 2GB.
Instead we should call __alloc_bootmem_low().

Subject: [S390] system.h: Fix compile error for 1 and 2 byte cmpxchg

commit 024914477e15ef8b17f271ec47f1bb8a589f0806 "memcg: move charges of anonymous
swap" revealed that the 1 byte and 2 byte cmpxchg is currently broken:

arch/s390/include/asm/system.h: Assembler messages:
arch/s390/include/asm/system.h:241: Error: junk at end of line: `(%r5)'
make[1]: *** [mm/page_cgroup.o] Error 1
make[1]: *** Waiting for unfinished jobs....

It turned out that commit 987bcdacb18a3adc2a48d85c9b005069c2f4dd7b ([S390] use
inline assembly contraints available with gcc 3.3.3) broke the inline assembly.
The or operands are now in constraint 3 and 4 instead of 2 and 3.

Subject: x86/PCI: truncate _CRS windows with _LEN > _MAX - _MIN + 1

Yanko's GA-MA78GM-S2H (BIOS F11) reports the following resource in a PCI
host bridge _CRS:

    [07] 32-Bit DWORD Address Space Resource
         Min Relocatability : MinFixed
         Max Relocatability : MaxFixed
            Address Minimum : CFF00000  (_MIN)
            Address Maximum : FEBFFFFF  (_MAX)
             Address Length : 3EE10000  (_LEN)

This is invalid per spec (ACPI 4.0, 6.4.3.5) because it's a fixed size,
fixed location descriptor, but _LEN != _MAX - _MIN + 1.

Based on https://bugzilla.kernel.org/show_bug.cgi?id=15480#c15, I think
Windows handles this by truncating the window so it fits between _MIN and
_MAX.  I also verified this by modifying the SeaBIOS DSDT and booting
Windows 2008 R2 with qemu.

This patch makes Linux truncate the window, too, which fixes:

Subject: x86: Make sure free_init_pages() frees pages on page boundary

When CONFIG_NO_BOOTMEM=y, it could use memory more effiently, or
in a more compact fashion.

Example:

 Allocated new RAMDISK: 00ec2000 - 0248ce57
 Move RAMDISK from 000000002ea04000 - 000000002ffcee56 to 00ec2000 - 0248ce56

The new RAMDISK's end is not page aligned.
Last page could be shared with other users.

When free_init_pages are called for initrd or .init, the page
could be freed and we could corrupt other data.

code segment in free_init_pages():

 |        for (; addr < end; addr += PAGE_SIZE) {
 |                ClearPageReserved(virt_to_page(addr));
 |                init_page_count(virt_to_page(addr));
 |                memset((void *)(addr & ~(PAGE_SIZE-1)),
 |                        POISON_FREE_INITMEM, PAGE_SIZE);
 |                free_page(addr);
 |                totalram_pages++;
 |        }

last half page could be used as one whole free page.

So page align the boundaries.

-v2: make the original initramdisk to be aligned, according to
     Johannes, otherwise we have the chance to lose one page.
     we still need to keep initrd_end not aligned, otherwise it could
     confuse decompressor.
-v3: change to WARN_ON instead, suggested by Johannes.
-v4: use PAGE_ALIGN, suggested by Johannes.
     We may fix that macro name later to PAGE_ALIGN_UP, and PAGE_ALIGN_DOWN
     Add comments about assuming ramdisk start is aligned
     in relocate_initrd(), change to re get ramdisk_image instead of save it
     to make diff smaller. Add warning for wrong range, suggested by Johannes.
-v6: remove one WARN()
     We need to align beginning in free_init_pages()
     do not copy more than ramdisk_size, noticed by Johannes

For 32-bit processes, we save the full 64-bits of the regs in pt_regs.

But unlike when the userspace actually does load and store
instructions, the top 32-bits don't get automatically truncated by the
cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM
address masking enabled).

So we have to do it by hand.

Subject: OMAP: HWMOD: Adding clockdomain check

This patch adds check for presence of clockdomain structure in the API
omap_hwmod_get_pwrdm before trying to access the powerdomain structure.
This will prevent unnecessary crashing of the system in case of a
clock node with out an associated clockdomain.

Subject: OMAP3: clock: fix enable bit used for dpll4_m4x2 clock

The enable bit for dpll4_m4x2 clock should be OMAP3430_PWRDN_DSS1_SHIFT.
The code erroneously uses OMAP3430_PWRDN_CAM_SHIFT which is meant for
dpll4_m5x2 clock.

This came into notice during a recent review of the clock tree.
