2007-05-23[POWERPC] QE: fix Kconfig 'select' warning with UCC_FASTTimur Tabi
The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used on PowerPC builds. On other architectures, this would generated a warning. The fix is to have UCC_FAST depend on UCC_GETH.

Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc broke things for us because we ended up with *(.text.*) before *(.text), whereas previously *(.text) was first. This was important because the start of the text section contains the kernel entry point. In fact, we don't need that *(.text.*) thing anymore and it incorrectly matched .text.init.refok, thus putting it before .text. .. ouch !

pmc.c has: #ifndef MMCR0_PMA0 #define MMCR0_PMA0 0 This one took a while to find. Unfortunately its the wrong define (number 0 vs letter O). Its probably worth removing this override, since if our includes get screwed up we will have the same (hard to debug) failure. Fix it simply for now, so that we can backport to stable.

2007-05-21x86_64: vsyscall time() fixjohn stultz
The vsyscall time() function basically returns the second portion of xtime directly. This however means that there is about a ticks worth of time each second where time() will return a second value less then what gettimeofday() does. Additionally, this window where vtime() is behind vgettimeofday() grows when dynticks is enabled, so its probably good to get this in before dynticks lands. Big thanks to Sripathi for noticing this issue and creating a test case to work with! This patch changes the vtime() implemenation to call vgettimeofday(), much as syscall time() implementation calls gettimeofday(). 2.6.21 stable candidate too Signed-off-by: John Stultz <johnstul@us.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-05-21x86_64: early_print kernel console should send CRLF not LFCRYinghai Lu
In commit d358788f3f30113e49882187d794832905e42592 Author: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Mon Mar 20 20:00:09 2006 +0000 Glen Turner reported that writing LFCR rather than the more traditional CRLF causes issues with some terminals. Since this afflicts many serial drivers, extract the common code to a library function (uart_console_write) and arrange for each driver to supply a "putchar" function. but early_printk is left out.

2007-05-21Blackfin arch: fix signal handling bugBernd Schmidt
There's a forum thread at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741 which has a testcase involving signal handling that crashes quite readily. Inspecting the code I believe what happens is that signal handling can become confused when it is invoked on return from an interrupt, if the contents of P0 and R0 at the time of the interrupt happen to be such that P0 is larger than zero (indicating to the signal code that we're in a syscall), and R0 happens to have a value of something like -EINTR or -ERESTARTSYS. Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The testcase now seems to run without problems.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
