[IA64] fix kmalloc(0) in arch/ia64/pci/pci.c
[IA64] Only unwind non-running tasks.
[IA64] Improve unwind checking.
[IA64] Yet another section mismatch warning
[IA64] Fix bogus messages about system calls not implemented. -
Hiroyuki Kamezawa reported the problem that pci_acpi_scan_root() of
ia64 might call kmalloc_node() with zero size.Currently ia64's pci_acpi_scan_root() assumes that _CRS method of root
bridge has at least one resource window. But, the root bridges that
has no resource window must be taken into account.Signed-off-by: Kenji Kaneshige

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.Signed-off-by: Robin Holt

This patch adds some sanity checks to keep register and memory stack

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 !Signed-off-by: Benjamin Herrenschmidt

pmc.c has:
#ifndef MMCR0_PMA0
#define MMCR0_PMA0 0This 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.

smp_call_function_map() was not safe against preemption to another
cpu: its test for removing self from map was outside the spinlock.
Rearrange it a little to fix that.smp_call_function_single() was also wrong: now get_cpu() before
excluding self, as other architectures do.Signed-off-by: Hugh Dickins

cr4 is a 32-bit register, so casting the mask to an unsigned char is wrong,

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

commit d358788f3f30113e49882187d794832905e42592
Author: Russell King
Date: Mon Mar 20 20:00:09 2006 +0000Glen 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.

- boot/setup.S did not print "PANIC: CPU too old for this kernel"
( not visible, also the message did not match )
- I add "# missed before: set ds"
=> somebody should check if I am right with the way to set.
=> seems to be a generic error in setup.S not to set "ds" for error messages.AK: extracted patch out of other changes
AK: also couldn't find any other case where ds is wrong

Only try to allocate MSRs once instead of for every CPU.
This assumes the MSRs are the same on all CPUs which is currently
true. P4-HT is a special case for different SMT threads, but the code
always saves/restores all MSRs so it works identical.Signed-off-by: Andi Kleen

There's a forum thread at
https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741which 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.Signed-off-by: Bernd Schmidt

Without conswitchp preset, we have the following situation:
- During initcalls: con_init is called, and returns because of
!display_desc.- At this point there is no memory allocated for vc_cons[].d
A bit later vty_init calls kbd_init.- From now on events are passed to kbd_event which will then call
kbd_keycode.- kbd_keycode will oops on a NULL pointer dereference on vc->vc_tty
