2014-03-19QE: split function mpc85xx_qe_init() into two functions.Zhao Qiang
New QE doesn't have par_io, it doesn't need to init par_io for new QE. Split function mpc85xx_qe_init() into mpc85xx_qe_init() and mpc85xx_qe_par_io_init(). Call mpc85xx_qe_init() for both new and old while mpc85xx_qe_par_io_init() after mpc85xx_qe_init() for old.

2014-03-19ixgbevf: Protect ixgbevf_down with __IXGBEVF_DOWN bitMark Rustad
The ixgbevf_down function can now prevent multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN. This did not work before introduction of the __IXGBEVF_REMOVING bit, because of overloading of __IXGBEVF_DOWN. Also add smp_mb__before_clear_bit call before clearing the __IXGBEVF_DOWN bit.

2014-03-19ixgbevf: Indicate removal state explicitlyMark Rustad
Add a bit, __IXGBEVF_REMOVING, to indicate that the module is being removed. The __IXGBEVF_DOWN bit had been overloaded for this purpose, but that leads to trouble. A few places now check both __IXGBEVF_DOWN and __IXGBEVF_REMOVING.

2014-03-19e1000e: Fix Hardware Unit HangDavid Ertman
The check for pending Tx work when link is lost was mistakenly moved to be done only when link is first detected to be lost. It turns out there is a small window of opportunity for additional Tx work to get queued up shortly after link is dropped. Move the check back to the place it was before in the watchdog task. Put in additional debug information for other reset paths and a final catch-all for false hangs in the scheduled function that prints out the hardware hang message.

When using an rbtree cache, there can be allocations the first time a register is accessed. This can cause an attempt to schedule while atomic in the case that the regmap is using a spinlock. This could be fixed by either initializing all the registers or using a flat cache. The register maps for tegra30_ahub and tegra30_i2s are dense and don't save much from using a tree so convert them to flat. Tegra30 changes tested on Norrin, Tegra20 changes compile.

2014-03-19x86, boot: Move memset() definition in compressed/string.cVivek Goyal
Currently compressed/misc.c needs to link against memset(). I think one of the reasons of this need is inclusion of various header files which define static inline functions and use memset() inside these. For example, include/linux/bitmap.h I think trying to include "../string.h" and using builtin version of memset does not work because by the time "#define memset" shows up, it is too late. Some other header file has already used memset() and expects to find a definition during link phase. Currently we have a C definitoin of memset() in misc.c. Move it to compressed/string.c so that others can use it if need be.

Move optimized definition of memcmp() in boot/string.c. Now a user can do #undef memcmp and link against string.c to use optimzied memcmp().

2014-03-19x86, boot: Create a separate string.h file to provide standard string functionsVivek Goyal
Create a separate arch/x86/boot/string.h file to provide declaration of some of the common string functions. By default memcpy, memset and memcmp functions will default to gcc builtin functions. If code wants to use an optimized version of any of these functions, they need to #undef the respective macro and link against a local file providing definition of undefed function. For example, arch/x86/boot/* code links against copy.S to get memcpy() and memcmp() definitions. arch/86/boot/compressed/* links against compressed/string.c. There are quite a few places in arch/x86/ where these functions are used. Idea is to try to consilidate their declaration and possibly definitions so that it can be reused. I am planning to reuse boot/string.h in arch/x86/purgatory/ and use gcc builtin functions for memcpy, memset and memcmp.

2014-03-19x86, boot: Undef memcmp before providing a new definitionVivek Goyal
With CONFIG_X86_32=y, string_32.h gets pulled in compressed/string.c by "misch.h". string_32.h defines a macro to map memcmp to __builtin_memcmp(). And that macro in turn changes the name of memcmp() defined here and converts it to __builtin_memcmp(). I thought that's not the intention though. We probably want to provide our own optimized definition of memcmp(). If yes, then undef the memcmp before we define a new memcmp.

2014-03-19MIPS: ftrace: Tweak safe_load()/safe_store() macrosViller Hsiao
Due to name collision in ftrace safe_load and safe_store macros, these macros cannot take expressions as operands. For example, compiler will complain for a macro call like the following: safe_store_code(new_code2, ip + 4, faulted); arch/mips/include/asm/ftrace.h:61:6: note: in definition of macro 'safe_store' : [dst] "r" (dst), [src] "r" (src)\ ^ arch/mips/kernel/ftrace.c:118:2: note: in expansion of macro 'safe_store_code' safe_store_code(new_code2, ip + 4, faulted); ^ arch/mips/kernel/ftrace.c:118:32: error: undefined named operand 'ip + 4' safe_store_code(new_code2, ip + 4, faulted); ^ arch/mips/include/asm/ftrace.h:61:6: note: in definition of macro 'safe_store' : [dst] "r" (dst), [src] "r" (src)\ ^ arch/mips/kernel/ftrace.c:118:2: note: in expansion of macro 'safe_store_code' safe_store_code(new_code2, ip + 4, faulted); ^ This build error is triggered by a4671094 [MIPS: ftrace: Fix icache flush range error]. Tweak variable naming in those macros to allow flexible operands.

2014-03-19[SCSI] vmw_pvscsi: Some improvements in pvscsi driver.Arvind Kumar
This change is about the following: (1) If the number of targets is 16+ then default ring_pages to 32. (2) Change default queue depth (per device) to 254. (3) Implement change_queue_depth function so that queue_depth per device can be changed at run time. Honors the request only if coming from sysfs. (4) Clean up the info returned by modinfo.

2014-03-19[SCSI] vmw_pvscsi: Fix pvscsi_abort() function.Arvind Kumar
This change ensures that pvscsi_abort() function returns SUCCESS only when the command in question was actually completed, otherwise returns FAILURE. The code before change, was causing a bug where driver tries to complete a command to the mid-layer while the mid-layer has already requested the driver to abort that command, in response to which the driver has responded with SUCCESS causing mid-layer to free the command struct.

2014-03-19[SCSI] ipr: Handle early EEHBrian King
If, when the ipr driver loads, the adapter is in an EEH error state, it will currently oops and not be able to recover, as it attempts to access memory that has not yet been allocated. We've seen this occur in some kexec scenarios. The following patch fixes the oops and also allows the driver to recover from these probe time EEH errors.

This adds a module parameter to enable clustering. Without enabling clustering support, the transfer length for read and write scsi commands is limited upto 8MB when page size is 4KB and sg_tablesize is 2048 (= SCSI_MAX_SG_CHAIN_SEGMENTS). I would like to test commands with more than that transfer length. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Reviewed-by: Douglas Gilbert <dgilbert@interlog.com> Reviewed-by: Martin K.
