2015-04-03char: xillybus: Don't return -EFAULT on user-triggered flushEli Billauer1-0/+2
The API allows the application to flush a host-to-FPGA stream by calling write() with the data count set to zero. Before this patch, copy_from_user() was called with a non-zero byte count, which possibly made it attempt to read from unmapped user memory. Such attempts caused the driver to return -EFAULT instead of 0, even though the desired operation went through fine. This patch ensures the driver returns 0 on a successful flush.

2015-04-03misc: pass miscdevice through file's private_dataTom Van Braeckel1-3/+8
Make the miscdevice accessible through the file's private_data. Previously, this was done only when an open() file operation had been registered. If no custom open() file operation was defined, private_data was set to NULL. This subtle quirk was confusing, to the point where kernel code registered *empty* file open operations to have private_data point to the misc device structure and avoid duplicating that logic. And it could easily lead to bugs, where the addition or removal of a custom open() file operation surprisingly changes the initial value of a file's private_data structure. To resolve this, we now place the miscdevice in the file's private_data member unconditionally when open() is called.

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for v4.1 This patchset include two new extcon driver and fix minor issue of extcon driver. Detailed description for patchset: 1. new extcon-max77843.c and extcon-usb-gpio.c extcon driver - extcon-max77843.c driver support the MAXIM MAX77843 MUIC (Micor-USB Interface Controller) device which handles the various external connectors such as TA/USB /USB-HOST/JIG and so on. - extcon-usb-gpio.c driver support the USB and USB-HOST cable detection by using the GPIO pin which is connected to USB ID pin. This GPIO pin updates the USB cable states. 2. Rename the filename of extcon core driver and add missing locking mechanism - Rename the previous extcon-class driver.c as extcon.c because '-class' postfix is not necessary word. - extcon core driver (extcon.c) used the raw_notifier_chain. It must be protected by locking mechanism to avoid the list changing while extcon_update_state() is executed. 3. Fix minor issue of extcon drviers - Fix cable name by using the capital letter instead of small letter on extcon-max77693.c driver. - Clean-up code of extcon-arizona.c to detect headphone cable. - Fix the wrong return type and variable type on extcon-max77843.c. - Fix the checkpatch warning of all extcon drivers.
2015-03-27memory: jz4780-nemc: driver for the NEMC on JZ4780 SoCsAlex Smith4-0/+444
Add a driver for the NAND/External Memory Controller (NEMC) on JZ4780 and later SoCs. The primary function of this driver is to configure parameters, such as timings, for external memory devices using data supplied in the device tree. Devices connected to the NEMC are represented in the DT as children of the NEMC node, the driver uses optional properties specified in these child nodes to configure the parameters of each bank.

2015-03-25Drivers: hv: hv_balloon: don't lose memory when onlining order is not naturalVitaly Kuznetsov1-10/+4
Memory blocks can be onlined in random order. When this order is not natural some memory pages are not onlined because of the redundant check in hv_online_page(). Here is a real world scenario: 1) Host tries to hot-add the following (process_hot_add): pg_start=rg_start=0x48000, pfn_cnt=111616, rg_size=262144 2) This results in adding 4 memory blocks: [ 109.057866] init_memory_mapping: [mem 0x48000000-0x4fffffff] [ 114.102698] init_memory_mapping: [mem 0x50000000-0x57ffffff] [ 119.168039] init_memory_mapping: [mem 0x58000000-0x5fffffff] [ 124.233053] init_memory_mapping: [mem 0x60000000-0x67ffffff] The last one is incomplete but we have special has->covered_end_pfn counter to avoid onlining non-backed frames and hv_bring_pgs_online() function to bring them online later on. 3) Now we have 4 offline memory blocks: /sys/devices/system/memory/memory9-12 $ for f in /sys/devices/system/memory/memory*/state; do echo $f `cat $f`; done | grep -v onlin /sys/devices/system/memory/memory10/state offline /sys/devices/system/memory/memory11/state offline /sys/devices/system/memory/memory12/state offline /sys/devices/system/memory/memory9/state offline 4) We bring them online in non-natural order: $grep MemTotal /proc/meminfo MemTotal: 966348 kB $echo online > /sys/devices/system/memory/memory12/state && grep MemTotal /proc/meminfo MemTotal: 1019596 kB $echo online > /sys/devices/system/memory/memory11/state && grep MemTotal /proc/meminfo MemTotal: 1150668 kB $echo online > /sys/devices/system/memory/memory9/state && grep MemTotal /proc/meminfo MemTotal: 1150668 kB As you can see memory9 block gives us zero additional memory. We can also observe a huge discrepancy between host- and guest-reported memory sizes. The root cause of the issue is the redundant pg >= covered_start_pfn check (and covered_start_pfn advancing) in hv_online_page(). When upper memory block in being onlined before the lower one (memory12 and memory11 in the above case) we advance the covered_start_pfn pointer and all memory9 pages do not pass the check. If the assumption that host always gives us requests in sequential order and pg_start always equals rg_start when the first request for the new HA region is received (that's the case in my testing) is correct than we can get rid of covered_start_pfn and pg >= start_pfn check in hv_online_page() is sufficient.

2015-03-23metag: Fix ioremap_wc/ioremap_cached build errorsJames Hogan3-94/+106
When ioremap_wc() or ioremap_cached() are used without first including asm/pgtable.h, the _PAGE_CACHEABLE or _PAGE_WR_COMBINE definitions aren't found, resulting in build errors like the following (in next-20150323 due to "lib: devres: add a helper function for ioremap_wc"): lib/devres.c: In function ‘devm_ioremap_wc’: lib/devres.c:91: error: ‘_PAGE_WR_COMBINE’ undeclared We can't easily include asm/pgtable.h in asm/io.h due to dependency problems, so split out the _PAGE_* definitions from asm/pgtable.h into a separate asm/pgtable-bits.h header (as a couple of other architectures already do), and include that in io.h instead.

2015-03-23extcon: Fix missing locking when [un]registering notifiersHans de Goede1-4/+31
Since extcon.c is using raw_notifiers it must protect the notifier list itself when [un]registering notifiers to avoid the list changing while extcon_update_state is walking the list (through raw_notifier_call_chain).

The i2c_new_dummy() return the NULL if error happen. So, If i2c_new_dummy() return NULL, max77843_init_muic_regmap() return the proper error value (-ENOMEM); Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> [cw00.choi: Use -ENOMEM instead of -ENODEV and modify patch description] Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
