[Linux-stable-mirror] [PATCH AUTOSEL for-3.18 01/27] extcon: palmas: Check the parent instance to prevent the NULL
From: Roger Quadros rogerq@ti.com
[ Upstream commit 9fe172b9be532acc23e35ba693700383ab775e66 ]
extcon-palmas must be child of palmas and expects parent's drvdata to be valid. Check for non NULL parent drvdata and fail if it is NULL. Not doing so will result in a NULL pointer dereference later in the probe() parent drvdata is NULL (e.g. misplaced extcon-palmas node in device tree).

We need to also have OFFPULLUDENABLE bit set to use the off mode pull values. Otherwise the line is pulled down internally if no external pull exists.
This is has some documentation at:
http://processors.wiki.ti.com/index.php/Optimizing_OMAP35x_and_AM/DM37x_OFF_...
Note that the value is still glitchy during off mode transitions as documented in spz319f.pdf "Advisory 1.45". It's best to use external pulls instead of relying on the internal ones for off mode and even then anything pulled up will get driven down momentarily on off mode restore for GPIO banks other than bank1.

Several people have reported firmware leaving the I210/I211 PHY's page select register set to something other than the default of zero. This causes the first accesses, PHY_IDx register reads, to access something else, resulting in device probe failure:
igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k igb: Copyright (c) 2007-2014 Intel Corporation. igb: probe of 0000:01:00.0 failed with error -2
This problem began for them after a previous patch I submitted was applied:
commit 2a3cdead8b408351fa1e3079b220fa331480ffbc Author: Aaron Sierra asierra@xes-inc.com Date: Tue Nov 3 12:37:09 2015 -0600
igb: Remove GS40G specific defines/functions
I personally experienced this problem after attempting to PXE boot from I210 devices using this firmware:
Intel(R) Boot Agent GE v1.5.78 Copyright (C) 1997-2014, Intel Corporation
Resetting the PHY before reading from it, ensures the page select register is in its default state and doesn't make assumptions about the PHY's register set before the PHY has been probed.

Similar to ixgbe, when an interface is part of a namespace it is possible that igb_close() may be called while __igb_shutdown() is running which ends up in a double free WARN and/or a BUG in free_msi_irqs().
Extend the rtnl_lock() to protect the call to netif_device_detach() and igb_clear_interrupt_scheme() in __igb_shutdown() and check for netif_device_present() to avoid calling igb_clear_interrupt_scheme() a second time in igb_close().
Also extend the rtnl lock in igb_resume() to netif_device_attach().

On loosely ordered memory systems (PPC for example), the WQE elements were being updated in memory, but not necessarily flushed before the separate doorbell was written to hw which would cause hw to dma the WQE element. Thus, the hardware occasionally received partially updated WQE data.
Add the memory barrier after updating the WQE memory.

Once device_register is called for a device its attributes might be accessed. As the callbacks of a lcd device's attributes make use of the lcd_ops, the respective member must be setup before calling device_register.

The pseudo DMA transfer codes in VX222 and VX-pocket driver have a slight bug where they check the buffer boundary wrongly, and may overflow. Also, the zero sample count might be handled badly for the playback (although it shouldn't happen in theory). This patch addresses these issues.

When building a kernel targeting a microMIPS ISA, recent GNU linkers will fail the link if they cannot determine that the target of a branch or jump is microMIPS code, with errors such as the following:
mips-img-linux-gnu-ld: arch/mips/built-in.o: .text+0x542c: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. mips-img-linux-gnu-ld: final link failed: Bad value
or:
./arch/mips/include/asm/uaccess.h:1017: warning: JALX to a non-word-aligned address
Placing anything other than an instruction at the start of a function written in assembly appears to trigger such errors. In order to prepare for allowing us to follow function prologue macros with an EXPORT_SYMBOL invocation, end the prologue macros (LEAD, NESTED & FEXPORT) with a .insn directive. This ensures that the start of the function is marked as code, which always makes sense for functions & safely prevents us from hitting the link errors described above.

When an interface is part of a namespace it is possible that ixgbe_close() may be called while __ixgbe_shutdown() is running which ends up in a double free WARN and/or a BUG in free_msi_irqs().
To handle this situation we extend the rtnl_lock() to protect the call to netif_device_detach() and ixgbe_clear_interrupt_scheme() in __ixgbe_shutdown() and check for netif_device_present() to avoid clearing the interrupts second time in ixgbe_close();
Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().

Memories managed through boot_mem_map are generally expected to define non-crossing areas. However, if part of a larger memory block is marked as reserved, it would still be added to bootmem allocator as an available block and could end up being overwritten by the allocator.
Prevent this by explicitly marking the memory as reserved it if exists in the range used by bootmem allocator.

Code in arch/mips/netlogic/common/irq.c which handles the XLP PIC fails to build in XLR configurations due to cpu_is_xlp9xx not being defined, leading to the following build failure:
arch/mips/netlogic/common/irq.c: In function ‘xlp_of_pic_init’: arch/mips/netlogic/common/irq.c:298:2: error: implicit declaration of function ‘cpu_is_xlp9xx’ [-Werror=implicit-function-declaration] if (cpu_is_xlp9xx()) { ^
Although the code was conditional upon CONFIG_OF which is indirectly selected by CONFIG_NLM_XLP_BOARD but not CONFIG_NLM_XLR_BOARD, the failing XLR with CONFIG_OF configuration can be configured manually or by randconfig.
Fix the build failure by making the affected XLP PIC code conditional upon CONFIG_CPU_XLP which is used to guard the inclusion of asm/netlogic/xlp-hal/xlp.h that provides the required cpu_is_xlp9xx function.

[ Upstream commit 44079d3509aee89c58f3e4fd929fa53ab2299019 ]
When relocatable support for MIPS was merged, there was no support for an architecture to add a postlink step for vmlinux. This meant that only invoking a target within the boot directory, such as uImage, caused the relocations to be inserted into vmlinux. Building just the vmlinux target would result in a relocatable kernel with no relocation information present.
Commit fbe6e37dab97 ("kbuild: add arch specific post-link Makefile") recified this situation, so MIPS can now define a postlink step to add relocation information into vmlinux, and remove the additional steps tacked onto boot targets.
