2007-05-29[SPARC64]: PCI device scan is way too verbose by default.David S. Miller
These messages were very useful when bringing up the OBP based PCI device scan code, but it's just a lot of noise every bootup now especially on big machines. The messages can be re-enabled via 'ofpci_debug=1' on the kernel command line. Signed-off-by: David S. Miller <davem@davemloft.net>

The meth ethernet driver for the SGI IP32 aka O2 is so far still an old style driver which does not use the device driver model. This is now causing issues with some udev based gadgetry in debian-stable. Fixed by converting the meth driver to a platform device.

2007-05-24[IA64] acpi_get_sysname() should be __initTony Luck
Section mismatch: reference to .init.text:acpi_find_rsdp (between 'acpi_get_sysname' and 'acpi_request_vector') acpi_get_sysname() needs to call the __init function acpi_find_rsdp, but it doesn't have the __init attribute itself, hence the warning. Luckily it is only called from machvec_init() which has __init attribute, so the fix is to define acpi_get_sysname() as __init too. Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-05-22[IA64] Only unwind non-running tasks.Robin Holt
Unwinding a running task has proven problematic. In one instance, the running task was attempting to unwind itself and received an interrupt between when get_wchan allocated local variables on the stack and when unw_init_from_blocked_task was called which resulted in unw_init_frame_info to place this tasks task_struct pointer over the switch stack's ar_bspstore entry.

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 !

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.
