Michal Simek 363922946f microblaze: Do not show error message for 32 interrupt lines
When interrupt controller uses 32 interrupts lines the kernel
show error message about mismatch in kind-of-intr parameter
because it exceeds u32. Recast fixs this issue.

Michal Simek e721a45fbe microblaze: Get early printk console earlier
1. Register early console as standard console
2. Enable CON_BOOT console flag to ensure auto-unregistering by the kernel
3. remap_early_printk function remap physical console baseaddr to virtual space

Usage specific function for console remap is done after memory initialization
with IRQ turn off that's why there is not necessary to protect it.

The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping
to be able to use console in very early boot-up phase. But allocating one TLB
just for console caused performance degression that's why ioremaps create new
mapping and TLB 63 is automatically released and ready to use.

Michal Simek c11389406f microblaze: Fix unaligned value saving to the stack for system with MMU
Several registers weren't saved correctly to the stack.

Unaligned expection for system with MMU stores
value in ex_tmp_data_loc_X address which is load to registers r3.
The next step is to move this value from r3 to a destination
register which caused unaligned exception. For several registers
this value was directly moved to the register.

For example for r28:
by "or r28, r0, r3"

but register r28 was rewritten when kernel returns from exception
handler by value saved on stack.

This patch changed r3 saving to the correct address on the stack.
For example for r28:
by "swi r3, r1, 4 * 28"

When kernel returns from the exception handler, correct value is restored.

Do not trace arch_local_save_flags(), arch_local_irq_*() and friends.
Although they are marked inline, gcc may still make a function out of
them and add it to the pool of functions that are traced by the function
tracer. This can cause undesirable results (kernel panic, triple faults,
etc).

Add the notrace notation to prevent them from ever being traced.

The whole business with re-assigning all bus numbers, creating

Benjamin Herrenschmidt 98d9f30c82 pci/of: Match PCI devices to OF nodes dynamically
powerpc has two different ways of matching PCI devices to their
corresponding OF node (if any) for historical reasons. The ppc64 one
does a scan looking for matching bus/dev/fn, while the ppc32 one does a
scan looking only for matching dev/fn on each level in order to be
agnostic to busses being renumbered (which Linux does on some
platforms).

This removes both and instead moves the matching code to the PCI core
itself. It's the most logical place to do it: when a pci_dev is created,
we know the parent and thus can do a single level scan for the matching
device_node (if any).

The benefit is that all archs now get the matching for free. There's one
hook the arch might want to provide to match a PHB bus to its device
node. A default weak implementation is provided that looks for the
parent device device node, but it's not entirely reliable on powerpc for
various reasons so powerpc provides its own.

Linus Torvalds 571503e100 Merge branch 'setns'
* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call
2011-05-28 10:51:01 -07:00
Eric W. Biederman 7b21fddd08 ns: Wire up the setns system call
32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

Michal Simek 56d448010f microblaze: Fix level/edge irq sensibility
Patches:
"microblaze: Convert to new irq function names"
sha (4adc192ec7)
and
"microblaze: Use generic show_interrupts()"
sha(9d61c18b25)

should also setup edge/level in irq_set_chip_and_handler_name
name parameter.

Error log:
~ # cat /proc/interrupts
           CPU0
  2:          2  Xilinx INTC-Xilinx INTC  eth0
  3:          2  Xilinx INTC-Xilinx INTC  eth0
  4:        241  Xilinx INTC-Xilinx INTC  timer
  6:        108  Xilinx INTC-Xilinx INTC  serial

Fixed:
~ # cat /proc/interrupts
           CPU0
  2:          2  Xilinx INTC-level     eth0
  3:          2  Xilinx INTC-level     eth0

Akinobu Mita 0664996b7c bitops: introduce CONFIG_GENERIC_FIND_BIT_LE
This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic
implementation of find_*_bit_le() in lib/find_next_bit.c or not.

For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which
enable CONFIG_GENERIC_FIND_NEXT_BIT.

But m68knommu wants to define own faster find_next_zero_bit_le() and
continues using generic find_next_{,zero_}bit().
(CONFIG_GENERIC_FIND_NEXT_BIT and !CONFIG_GENERIC_FIND_BIT_LE)
