| * Enable a way to provide the reason for "being here"Juergen Beisert2012-07-181-0/+27
| | | | | | | | | | | | | | | | | | | | Many architectures support a way to detect why the bootloader is running. This patch adds a global variable to be able to use the cause in some kind of shell code to do special things on demand. For example to do an emergency boot, when the last boot fails and the watchdog reactivate the hanging system.

Also it is reasonable to make serial driver's names unification. E.g. see the names for drivers in drivers/serial directory: "netx_serial", "mpc5xxx_serial", "altera_serial", "s3c_serial", "imx_serial", "pxa_serial", "blackfin_serial", "stm_serial", "pl010_serial", and even "g_serial" in ./drivers/usb/gadget/serial.c Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Linux commit 69349c2dc01c489eccaa4c472542c08e370c6d7e: Using IS_ENABLED() within C (vs. within CPP #if statements) in its current form requires us to actually define every possible bool/tristate Kconfig option twice (__enabled_* and __enabled_*_MODULE variants). This results in a huge autoconf.h file, on the order of 16k lines for a x86_64 defconfig. Fixing IS_ENABLED to be able to work on the smaller subset of just things that we really have defined is step one to fixing this. Which means it has to not choke when fed non-enabled options, such as: include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef] The original prototype of how to implement a C and preprocessor compatible way of doing this came from the Google+ user "comex ." in response to Linus' crowdsourcing challenge for a possible improvement on his earlier C specific solution: #define config_enabled(x) (__stringify(x)[0] == '1') In this implementation, I've chosen variable names that hopefully make how it works more understandable.

* fs: fix standard zero, full devicesSascha Hauer2012-07-042-0/+2
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.

| * resource: store 'end' instead of 'size' in struct resourceSascha Hauer2012-07-011-4/+4
| | | | | | | | | | | | | | | | | | | | Storing the size instead of the resource end in struct resource was a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
