The topology extension CPUID leafs are required to detect which

W/o this patch we wouldn't see which cores belong to the same

Provide the proper override macros for x32 siginfo_t.  The combination
of a special type here and an overall alignment constraint actually
ends up with all the types being properly aligned, but the hack is
needed to keep the substructures inside siginfo_t from adding padding.

Note: use __attribute__((aligned())) since __aligned() is not exported

For the particular issue of x32, which shares code with i386 in the
handling of compat_siginfo_t, the use of a 64-bit clock_t bumps the
sigchld structure out of alignment, which triggers a messy cascade of
padding.

This was already handled on the kernel compat side, but it needs
handling on the user space side, which uses the generic header.  To
make that possible:

1. Allow __kernel_clock_t to be overridden in struct siginfo;
2. Allow there to be attributes added to struct siginfo.

With commit a2ef5c4f
"ACPI: Move module parameter gts and bfs to sleep.c" the
wake_sleep_flags is required when calling acpi_enter_sleep_state.

The assembler code in wakeup_*.S did not do that. One solution
is to call it from assembler and stick the wake_sleep_flags on
the stack (for 32-bit) or in %esi (for 64-bit). hpa and rafael
both suggested however to create a wrapper function to call
acpi_enter_sleep_state and call said wrapper function
("acpi_enter_s3") from assembler.

For 32-bit, the acpi_enter_s3 ends up looking as so:

  push   %ebp
  mov    %esp,%ebp
  sub    $0x8,%esp
  movzbl 0xc1809314,%eax [wake_sleep_flags]
  movl   $0x3,(%esp)
  mov    %eax,0x4(%esp)
  call   0xc12d1fa0 <acpi_enter_sleep_state>
  leave
  ret

And 64-bit:

  movzbl 0x9afde1(%rip),%esi        [wake_sleep_flags]
  push   %rbp
  mov    $0x3,%edi
  mov    %rsp,%rbp
  callq  0xffffffff812e9800 <acpi_enter_sleep_state>

If the L3 disable slot is already in use, return -EEXIST instead of
-EINVAL. The caller, store_cache_disable(), checks this return value to
print an appropriate warning.

Also, we want to signal with -EEXIST that the current index we're
disabling has actually been already disabled on the node:

$ echo 12 > /sys/devices/system/cpu/cpu3/cache/index3/cache_disable_0
$ echo 12 > /sys/devices/system/cpu/cpu3/cache/index3/cache_disable_0
-bash: echo: write error: File exists

-bash: echo: write error: File exists
$ echo 12 > /sys/devices/system/cpu/cpu5/cache/index3/cache_disable_1
-bash: echo: write error: File exists

The old code would say

The method used to work out whether we were booted by EFI firmware or
via a boot loader is broken. Because efi_main() is always executed
when booting from a boot loader we will dereference invalid pointers
either on the stack (CONFIG_X86_32) or contained in %rdx
(CONFIG_X86_64) when searching for an EFI System Table signature.

Instead of dereferencing these invalid system table pointers, add a
new entry point that is only used when booting from EFI firmware, when
we know the pointer arguments will be valid. With this change legacy
boot loaders will no longer execute efi_main(), but will instead skip
EFI stub initialisation completely.

The 'max' range needs to be unsigned, since the size of the user address
space is bigger than 2GB.

We know that 'count' is positive in 'long' (that is checked in the
caller), so we will truncate 'max' down to something that fits in a
signed long, but before we actually do that, that comparison needs to be
done in unsigned.

Bug introduced in commit 92ae03f2 ("x86: merge 32/64-bit versions of
'strncpy_from_user()' and speed it up").  On x86-64 you can't trigger
this, since the user address space is much smaller than 63 bits, and on
x86-32 it works in practice, since you would seldom hit the strncpy
limits anyway.

I had actually tested the corner-cases, I had only tested them on
x86-64.  Besides, I had only worried about the case of a pointer *close*
to the end of the address space, rather than really far away from it ;)

This also changes the "we hit the user-specified maximum" to return
'res', for the trivial reason that gcc seems to generate better code
that way.  'res' and 'count' are the same in that case, so it really
doesn't matter which one we return.

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.

This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

During booting of cpu1, there is a short window where cpu1
is online, but not active where cpu1 is occupied by waiting
to become active. If cpu0 then decides to schedule something
on cpu1 and wait for it to complete, before cpu0 has set
cpu1 active, we have a deadlock.

Typically it's this CPU frequency transition that happens at
this time, so let's just not wait for it to happen, it will
happen whenever the CPU eventually comes online instead.

Commit 26f41062 ("PCI: check for pci bar restore completion and
retry") attempted to address problems with PCI BAR restoration on
systems where FLR had not been completed before pci_restore_state() was
called, but it did that in an utterly wrong way.

First off, instead of retrying the writes for the BAR registers only, it
did that for all of the PCI config space of the device, including the
status register (whose value after the write quite obviously need not be
the same as the written one).  Second, it added arbitrary delay to
pci_restore_state() even for systems where the PCI config space
restoration was successful at first attempt.  Finally, the mdelay(10) it
added to every iteration of the writing loop was way too much of a delay
for any reasonable device.

All of this actually caused resume failures for some devices on Mikko's
system.

To fix the regression, make pci_restore_state() only retry the writes
for BAR registers and only wait if the first read from the register
doesn't return the written value.  Additionaly, make it wait for 1 ms,
instead of 10 ms, after every failing attempt to write into config
space.

function if you do not select DEBUG_LL, so make the former select the latter.

Pull system.h fixups for less common arch's from Paul Gortmaker:
 "Here is what is hopefully the last of the system.h related fixups.

  The fixes for Alpha and ia64 are code relocations consistent with what
  was done for the more mainstream architectures.  Note that the
  diffstat lines removed vs lines added are not the same since I've
  fixed some of the whitespace issues in the relocated code blocks.
  However they are functionally the same.  Compile tested locally, plus
  these two have been in linux-next for a while.

  There is also a trivial one line system.h related fix for the Tilera
  arch from Chris Metcalf to fix an implict include.."

Pull fbdev fixes from Florian Tobias Schandinat:
 - a compile fix for au1*fb
 - a fix to make kyrofb usable on x86_64
 - a fix for uvesafb to prevent an oops due to NX-protection

 "The fix for kyrofb is a bit large but it's just replacing "unsigned
  long" by "u32" for 64 bit compatibility."
