Set the PCI CLS early in the boot process to prevent
device failures. In pcibios_set_master use the new
pci_cache_line_size instead of a hard-coded value.

Revert the change made to arch/ia64/sn/kernel/setup.c by commit
204fba4aa303ea4a7bb726a539bf4a5b9e3203d0 as it breaks the build.
Fixing the build the b94b08081fcecf83fa690d6c5664f6316fe72208 way
breaks xpc because genksyms then fails to generate an CRC for
per_cpu____sn_cnodeid_to_nasid because of limitations in the
generic genksyms code.

I create wrong asm code but none test shows that this part of code is wrong.
I am not convinces that were good idea to create asm optimized macros
for caches. The reason is that there is not optimization with previous code
that's why make sense to add old code and do some benchmarking which
functions are faster.

When the user enables breakpoints through dr7, he can choose
between "local" or "global" enable bits but given how linux is
implemented, both have the same effect.
That said we don't keep track how the user enabled the breakpoints
so when the user requests the dr7 value, we only translate the
"enabled" status using the global enabled bits. It means that if
the user enabled a breakpoint using the local enabled bit, reading
back dr7 will set the global bit and clear the local one.
Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated
softwares that implement old reverse engineering protection schemes.
We fix that by keeping track of the whole dr7 value given by the user
in the thread structure to drop this bug. We'll think about
something more proper later.
This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Before we had a generic breakpoint API, ptrace was accepting
breakpoints on NULL address in x86. The new API refuse them,
without given strong reasons. We need to follow the previous
behaviour as some userspace apps like Wine need such NULL
breakpoints to ensure old emulated software protections
are still working.
This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Commit 085219f79cad89291699bd2bfb21c9fdabafe65f
("sparc32: use proper types in struct stat")
Accidently changed the struct stat uid/gid members
to uid_t and gid_t, but those get set to
__kernel_uid32_t and __kernel_gid32_t respectively.
Those are of type 'int' but the structure is meant
to have 'short'. So use uid16_t and gid16_t to
correct this.

The check for a valid mux name should be performed regardless of whether
DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000
Internal error: Oops: 5 [#1]

CPU: 0 Not tainted (2.6.33-rc8 #10)
PC is at strcmp+0x18/0x40
LR is at omap_mux_init_signal+0x68/0x14c
...
This fixes the issue currently seen with boards not booting up
if DEBUG_FS is not enabled in defconfig.
Note that the earlier ifndef + ifdef now becomes simpler ifdef else:
If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected,
we only want the GPIO to mux register mapping.

Some glibc versions intentionally create lots of alignment faults in
their gconv code, which if not fixed up, results in segfaults during
boot. This can prevent systems booting properly.
There is no clear hard-configurable default for this; the desired
default depends on the nature of the userspace which is going to be
booted.
So, provide a way for the alignment fault handler to be configured via
the kernel command line.

The 'outer_cache' variable is needed by the outer_inv_range(),
outer_clean_range() and outer_flush_range() functions, which are
declared as inline in asm/cacheflush.h. Otherwise drivers built
as a loadable module, which access these functions, will have
an undefined symbol.

Thanks to testcase and report from Brad Spengler:
--------------------
#include <stdio.h>
typedef int (* _wee)(void);
int main(void)
{
char buf[8] = { '\x81', '\xc7', '\xe0', '\x08', '\x81', '\xe8',
'\x00', '\x00' };
_wee wee;
printf("%p\n", &buf);
wee = (_wee)&buf;
wee();
return 0;
}
--------------------
TSB I-tlb load code tries to use andcc to check the _PAGE_EXEC_4U bit,
but that's bit 12 so it gets sign extended all the way up to bit 63
and the test nearly always passes as a result.
Use sethi to fix the bug.

This also broke systems which invoked acpi=ht via DMI blacklist.

Recent U-Boot commit 5ccd29c3679b3669b0bde5c501c1aa0f325a7acb caused
the "cpu-release-addr" device tree property to contain the physical RAM
location that secondary cores were spinning at. Previously, the
"cpu-release-addr" property contained a value referencing the boot page
translation address range of 0xfffffxxx, which then indirectly accessed
RAM.
The "cpu-release-addr" is currently ioremapped and the secondary cores
kicked. However, due to the recent change in "cpu-release-addr", it
sometimes points to a memory location in low memory that cannot be
ioremapped. For example on a P2020-based board with 512MB of RAM the
following error occurs on bootup:

This is because mpic_alloc() assigns wrong values to
mpic->isu_{size,shift,mask}, and things eventually break when
_mpic_irq_read() is trying to use them.
This patch fixes the issue by enabling MPIC_BROKEN_FRR_NIRQS quirk.

[IA64] preserve personality flag bits across exec

| | | | | | | | |
In its <asm/elf.h> ia64 defines SET_PERSONALITY in a way that unconditionally
sets the personality of the current process to PER_LINUX, losing any flag bits
from the upper 3 bytes of current->personality. This is wrong. Those bits are
intended to be inherited across exec (other code takes care of ensuring that
security sensitive bits like ADDR_NO_RANDOMIZE are not passed to unsuspecting
setuid/setgid applications).

The 64-bit version of ELF_PLAT_INIT() clears TIF_IA32, but at this point
it has already been cleared by SET_PERSONALITY == set_personality_64bit.

This follows the parisc change to ensure that tracehook_signal_handler()
is aware of when we are single-stepping in order to ptrace_notify()
appropriately. While this was implemented for 32-bit SH, sh64 neglected
to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code,
resulting in ptrace_notify() never being called.
As sh64 uses all of the other abstractions already, this simply plugs in
the thread flag in the appropriate enable/disable paths and fixes up the
tracehook notification accordingly. With this in place, sh64 is brought
in line with what 32-bit is already doing.

Mike Frysinger pointed out that calling tracehook_signal_handler with
stepping=0 missed testing the thread flags, resulting in not calling
ptrace_notify. Fix this by testing if we're single stepping or branch
stepping and setting the flag accordingly.
Tested, seems to work.

The platform data allocated with kmalloc() will become unreachable once
the init is complete, so it should be freed. The problem was discovered

The patch that adds cpu_probe_vmbits is erroneously writing to reserved
bit 12. Since we are really only probing high bits, don't write this bit
with a one.

Test the value that was just allocated rather than the previously tested one.
