m32r: fix m32104ut_defconfig build fail

2016-02-25T20:01:22+00:00

commit 601f1db653217f205ffa5fb33514b4e1711e56d1 upstream.

The build of m32104ut_defconfig for m32r arch was failing for long long
time with the error:

  ERROR: "memory_start" [fs/udf/udf.ko] undefined!
  ERROR: "memory_end" [fs/udf/udf.ko] undefined!
  ERROR: "memory_end" [drivers/scsi/sg.ko] undefined!

  ERROR: "memory_end" [drivers/i2c/i2c-dev.ko] undefined!
  ERROR: "memory_start" [drivers/i2c/i2c-dev.ko] undefined!

As done in other architectures export the symbols to fix the error.

KVM: PPC: Fix ONE_REG AltiVec support

commit b4d7f161feb3015d6306e1d35b565c888ff70c9d upstream.

The get and set operations got exchanged by mistake when moving the
code from book3s.c to powerpc.c.

KVM: PPC: Fix emulation of H_SET_DABR/X on POWER8

2016-02-25T20:01:20+00:00

commit 760a7364f27d974d100118d88190e574626e18a6 upstream.

In the old DABR register, the BT (Breakpoint Translation) bit
is bit number 61. In the new DAWRX register, the WT (Watchpoint
Translation) bit is bit number 59. So to move the DABR-BT bit
into the position of the DAWRX-WT bit, it has to be shifted by
two, not only by one. This fixes hardware watchpoints in gdb of
older guests that only use the H_SET_DABR/X interface instead
of the new H_SET_MODE interface.

arm64: dma-mapping: fix handling of devices registered before arch_initcall

2016-02-25T20:01:20+00:00

commit 722ec35f7faefcc34d12616eca7976a848870f9d upstream.

This patch ensures that devices, which got registered before arch_initcall
will be handled correctly by IOMMU-based DMA-mapping code.

ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata

2016-02-25T20:01:20+00:00

commit 4da597d16602d14405b71a18d45e1c59f28f0fd2 upstream.

We don't want to write to .text so let's move ppa_zero_params and
ppa_por_params to .data and access them via pointers.

Note that I have not been able to test as we I don't have a HS
omap4 to test with. The code has been changed in similar way as
for omap3 though.

ARM: OMAP2+: Fix save_secure_ram_context for rodata

commit a5311d4d13df80bd71a9e47f9ecaf327f478fab1 upstream.

We don't want to write to .text and we can move save_secure_ram_context
into .data as it all gets copied into SRAM anyways.

ARM: OMAP2+: Fix l2dis_3630 for rodata

commit eeaf9646aca89d097861caa24d9818434e48810e upstream.

We don't want to write to .text section. Let's move l2dis_3630
to .data and access it via a pointer.

For calculating the offset, let's optimize out the add and do it
in ldr/str as suggested by Nicolas Pitre .

commit d9db59103305eb5ec2a86369f32063e9921b6ac5 upstream.

We don't want to be writing to .text so it can be set rodata.
Fix error "Unable to handle kernel paging request at virtual address
c012396c" in wait_dll_lock_timed if CONFIG_DEBUG_RODATA is selected.

As these counters are for debugging only and unused, we can just
remove them.
