2009-09-20kconfig: add symbol value to help find the real dependCheng Renquan
Sometimes when configuring need to disable some unused item, but the item is selected by many other items, it's hard to find the real dependency which selected it, This patch add every symbol's value accompanied to make it possible to find the real dependency easily. An example is CONFIG_RFKILL, ---------------------- RF switch subsystem support ---------------------- | CONFIG_RFKILL: | | | | Say Y here if you want to have control over RF switches | | found on many WiFi and Bluetooth cards. | | | | To compile this driver as a module, choose M here: the | | module will be called rfkill. | | | | Symbol: RFKILL [=m] | | Prompt: RF switch subsystem support | | Defined at net/rfkill/Kconfig:4 | | Depends on: NET [=y] | | Location: | | -> Networking support (NET [=y]) | | Selected by: IWLCORE [=n] && NETDEVICES [=y] && !S390 [=S390] && PC | | | ----------------------------------------------------------------( 99%)--- Signed-off-by: Cheng Renquan <crquan@gmail.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2009-09-20kbuild: save ARCH & CROSS_COMPILE when building a kernelSam Ravnborg
When building a kernel for a different architecture kbuild requires the user always to specify ARCH and CROSS_COMPILE on the command-line. We use the asm symlink to detect if user forgets to specify the correct ARCH value - but that symlink is about to die. And we do now want to loose this check. This patch save the settings of ARCH and CROSS_COMPILE in two files named: include/generated/kernel.arch include/generated/kernel.cross The settings are saved during "make *config" time and always read. If user try to change the settings we error out. This works both for plain builds and for O=... builds. So now you can do: $ mkdir sparc64 $ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig $ cd sparc64 $ make Notice that you no longer need to tell kbuild the settings of ARCH and CROSS_COMPILE when you type make in the output directory. Likewise for plain builds where you do not use O=... Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roland McGrath <roland@redhat.com>
2009-09-20kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg
Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

2009-09-18frv: clean up linker script using new linker script macros.Nelson Elhage
This is largely a straightforward conversion. The patch results in fewer output sections, and some data being reordered, but should have no functional impact. Also, note that this patch moves some data (namely, init_task and cacheline-aligned) inside [_sdata,_edata]. Because frv already builds using -ffunction-sections -fdata-sections, we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not currently include the required .bss.* and .data.* sections.

2009-09-18pty_write: don't do a tty_wakeup() when the buffers are fullLinus Torvalds
Commit ac89a9174 ("pty: don't limit the writes to 'pty_space()' inside 'pty_write()'") removed the pty_space() checking, in order to let the regular tty buffer code limit the buffering itself. That was all good, but as a subtle side effect it meant that we'd be doing a tty_wakeup() even in the case where the buffers were all filled up, and didn't actually make any progress on the write. Which sounds innocuous, but it interacts very badly with the ppp_async code, which has an infinite loop in ppp_async_push() that tries to push out data to the tty. When we call tty_wakeup(), that loop ends up thinking that progress was made (see the subtle interactions between XMIT_WAKEUP and 'tty_stuffed' for details). End result: one unhappy ppp user. Fixed by noticing when tty_insert_flip_string() didn't actually do anything, and then not doing any more processing (including, very much not calling tty_wakeup()).

2009-09-18[WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen
The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value. However, the book E wdt currently treats it as a "period" which is interpreted in a board-specific way. This patch allows the user to pass in a "seconds" value and the driver will set the smallest timeout that is at least as large as specified by the user. It's been tested on e500 hardware and works as expected. The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case is left unmodified as I don't have any hardware to test it on.

Merge reason: Suresh Siddha (1): x86, pat: don't use rb-tree based lookup in reserve_memtype() ... requires previous x86/pat commits already pushed to Linus. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2009-09-17x86, pat: don't use rb-tree based lookup in reserve_memtype()Suresh Siddha
Recent enhancement of rb-tree based lookup exposed a bug with the lookup mechanism in the reserve_memtype() which ensures that there are no conflicting memtype requests for the memory range. memtype_rb_search() returns an entry which has a start address <= new start address. And from here we traverse the linear linked list to check if there any conflicts with the existing mappings. As the rbtree is based on the start address of the memory range, it is quite possible that we have several overlapped mappings whose start address is much less than new requested start but the end is >= new requested end. This results in conflicting memtype mappings. Same bug exists with the old code which uses cached_entry from where we traverse the linear linked list. But the new rb-tree code exposes this bug fairly easily. For now, don't use the memtype_rb_search() and always start the search from the head of linear linked list in reserve_memtype(). Linear linked list for most of the systems grow's to few 10's of entries(as we track memory type of RAM pages using struct page). So we should be ok for now. We still retain the rbtree and use it to speed up free_memtype() which doesn't have the same bug(as we know what exactly we are searching for in free_memtype). Also use list_for_each_entry_from() in free_memtype() so that we start the search from rb-tree lookup result.
