Commit 6e7582bf35b8a5a330fd08b398ae445bac86917a
"MIPS: PowerTV: use free_reserved_area() to simplify code"
merged in 3.11-rc1, broke the build for the powertv defconfig with
the following build error:
arch/mips/powertv/asic/asic_devices.c: In function 'platform_release_memory':
arch/mips/powertv/asic/asic_devices.c:533:7: error: passing argument 1 of
'free_reserved_area' makes pointer from integer without a cast [-Werror]
The free_reserved_area() function expects a void * pointer for the start
address and a void * pointer for the end one.

If neither BCM47XX_SSD nor BCM47XX_BCMA is selected, then no

this problem by using MIPS32r1 as the default CPU type for

It wasn't until GCC 4.3 I believe that the __SIZEOF_*__ predefined macros
were added. The change below switches <uapi/asm/siginfo.h> to the
_MIPS_SZLONG macro so that compilation with e.g. GCC 4.1.2 succeeds.
This is a user API header so I think this is even more important, for
older userland support. The change adds an unsuccessful default too, to
catch any compiler configuration oddities.

Register target address to be used for cpgmac is the second device
address space. By default, hwmod picks first address space (0th index)
for register target.
With removal of address space from hwmod and using DT instead, cpgmac
is getting wrong address space for register target.
Fix it by indicating the address space to be used for register target.

Address space is being removed from hwmod database and DT information
in <reg> property is being used. Currently the 0th index of device
address space is used to map for register target address. This is not
always true, eg. cpgmac has it's sysconfig in second address space.
Handle it by specifying index of device address space to be used for
register target. As default value of this field would be zero with
static initialization, existing behaviour of using first address space
for register target while using DT would be kept as such.

Some hwmods which are marked with HWMOD_INIT_NO_IDLE are left in enabled
state post setup(). When a omap_device gets created for such hwmods
make sure the omap_device and pm_runtime states are also in sync for such
hwmods by doing a omap_device_enable() and pm_runtime_set_active() for the
device.

With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.
This was rootcaused to hwmod trying to reset console uart while
earlycon was using it. The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.
Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.
This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.
However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.
The following optional/unused regulators can be updated:
- SMPS9 supplies TWL6040 over VDDA_2v1_AUD. This regulator needs to be
enabled only when audio is active. Since it does not come active by
default, it does not require "always-on" or "boot-on".
- LDO2 and LDO8 do not go to any peripheral or connector on the board.
Further, these unused regulators should have been 2.8V for LDO2 and
3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.

commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.
However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.
The following fixes are hence mandatory to ensure right voltage is
supplied to key OMAP5 SoC voltage rails:
- LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This
can only be supplied at 1.5V or 1.8V and we currently supply 2.8V.
To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.
Remove 'always-on' and 'boot-on' settings here as it is
a 'on need' supply to SoC IP and is not enabled by PMIC by
default at boot.
- LDO3 supplies Low Latency Interface(LLI) hardware module which is a
special hardware to communicate with Modem. However since uEVM is
not setup by default for this communication, this should be disabled
by default.
Further, vdda_lli is supposed to be 1.5V and not 3V.
- LDO4 supplies VDDAPHY_DISP which is vdda_dsiporta/c/vdda_hdmi
This can only be supplied at 1.5V or 1.8V and we currently
supply 2.2V.
To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.
Remove 'always-on' and 'boot-on' settings here as it is a 'on need'
supply to SoC IP and is not enabled by PMIC by default at boot.
- LDO6 supplies the board specified VDDS_1V2_WKUP supply going to
ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply
1.2V instead of 1.5V.
- LDO7 supplies VDD_VPP which is vpp1. This is currently configured for
1.5V which as per data manual "A pulse width of 1000 ns and an amplitude
of 2V is required to program each eFuse bit. Otherwise, VPP1 must not
be supplied".
So, fix the voltage to 2V. and disable the supply since we have no plans
of programming efuse bits - it can only be done once - in factory.
Further it is not enabled by default by PMIC so, 'boot-on' must be
removed, and the 'always-on' needs to be removed to achieve pulsing
if efuse needs to be programmed.
- LDO9 supplies the board specified vdds_sdcard supply going within SoC
specification of 1.8V or 3.0V. Further the supply is controlled by
switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to
be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled
on need basis.

x86/mce: Update MCE severity condition check
We simplified the rules to recognise each classification of recoverable
machine check combining the instruction and data fetch rules into a
single entry based on clarifications in the June 2013 SDM that all
recoverable events would be reported on the unaffected processor with
MCG_STATUS.EIPV=0 and MCG_STATUS.RIPV=1. Unfortunately the simplified
rule has a couple of bugs. Fix them here.

During nested vmentry into vm86 mode a vcpu state is found to be incorrect
because rflags does not have VM flag set since it is read from the cache
and has L1's value instead of L2's. If emulate_invalid_guest_state=1 L0
KVM tries to emulate it, but emulation does not work for nVMX and it
never should happen anyway. Fix that by using vmx_set_rflags() to set
rflags during nested vmentry which takes care of updating register cache.

GCC will optimize mxcsr_feature_mask_init in arch/x86/kernel/i387.c:
memset(&fx_scratch, 0, sizeof(struct i387_fxsave_struct));
asm volatile("fxsave %0" : : "m" (fx_scratch));
mask = fx_scratch.mxcsr_mask;
if (mask == 0)
mask = 0x0000ffbf;
to
memset(&fx_scratch, 0, sizeof(struct i387_fxsave_struct));
asm volatile("fxsave %0" : : "m" (fx_scratch));
mask = 0x0000ffbf;
since asm statement doesn’t say it will update fx_scratch. As the
result, the DAZ bit will be cleared. This patch fixes it. This bug
dates back to at least kernel 2.6.12.

The perf_event code references sie_exit even if KVM is not available.
So add proper ifdefs to fix this one:
arch/s390/built-in.o: In function `sys_call_table_emu':
(.rodata+0x2b98): undefined reference to `sie_exit'
arch/s390/built-in.o: In function `sys_call_table_emu':
(.rodata+0x2ba0): undefined reference to `sie_exit'

The find_next_bit_left function is broken if used with an offset which
is not a multiple of 64. The shift to mask the bits of a 64-bit word
not to search is in the wrong direction, the result can be either a
bit found smaller than the offset or failure to find a set bit.
