2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan1-1/+1
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

2016-04-19arcnet: com90xx: add __init attributeJulia Lawall1-1/+1
Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 0000000000000000 l F .text.unlikely 00000000000000bf check_mirror And after the change it is as follows: 0000000000000000 l F .init.text 00000000000000ba check_mirror Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.

2015-11-03arcnet/com20020: add LEDS_CLASS dependencyArnd Bergmann1-0/+1
The newly added led trigger support in the com20020-pci driver causes build errors when CONFIG_LEDS_CLASS is disabled: drivers/built-in.o: In function `com20020pci_probe': (.text+0x185dc4): undefined reference to `devm_led_classdev_register' (.text+0x185dd8): undefined reference to `devm_led_classdev_register' This adds a Kconfig dependency to prevent the invalid configurations. Other drivers appear to be split 50:50 between 'select' and 'depends on' for this symbol, I picked 'depends on' as I could not find a common policy and it generally causes fewer problems.

2015-10-26arcnet: add netif_carrier_on/off for reconnectMichael Grzeschik2-0/+27
The arcnet device has no interrupt to detect if the link has changed from disconnected to connected. This patch adds an timer to toggle the link detection. The timer will get retriggered as long as the reconnection interrupts accure. If the recon interrupts hold off for >1s we define the connection stable again.

2015-10-26arcnet: com20020-pci: add rotary index supportMichael Grzeschik2-0/+37

2015-10-26arcnet: com20020-pci: set dev_port to the subdevice indexMichael Grzeschik1-0/+1

2015-10-26arcnet: com20020: add enable and disable device on open/closeMichael Grzeschik1-10/+29
This patch changes the driver to properly work with the linux netif interface. The controller gets enabled on open and disabled on close. Therefor it removes every bogus start of the xceiver.

2015-09-17ARCNET: fix hard_header_len limitMichael Grzeschik1-1/+1
For arcnet the bare minimum header only contains the 4 bytes to specify source, dest and offset (1, 1 and 2 bytes respectively). The corresponding struct is struct arc_hardware. The struct archdr contains additionally a union of possible soft headers. When doing $insertusecasehere packets might well include short (or even no?) soft headers. For this reason only use arc_hardware instead of archdr to determine the hard_header_len for an arcnet device. Signed-off-by: Michael Grzeschik <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2015-06-23drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker1-4/+0
This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <[email protected]> Signed-off-by: David S. Miller <[email protected]>
