Introduce per-net_device inlines: dev_net(), dev_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.

When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c,
the efi memory regions are displayed. This patch enhances the
display code in a few ways:
1. Use TB, GB and MB as well as KB as units.
Although this introduces rounding errors (KB doesn't as
size is always a multiple of 4Kb), it does make
things a lot more readable.
Also as the range is also shown, it is possible to note the exact size
if it is important. In my experience, the size field is mostly useful
for getting a general idea of the size of a region.
On the rx2620 that I use, there actually is an 8TB region (though not
backed by physical memory, and 8TB really is a lot more readable than
8589934592KB.
2. pad the size field with leading spaces to further improve readability
...
... ( 8MB)
... ( 928MB)
... ( 3MB)

vs

3. Pad the attr field out to 64bits using leading zeros,
to further improve readability.

Fix the problem that the following error message is sometimes displayed
at irq migration when vector domain is enabled.
"Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!"
The cause of this problem is an interrupt is sent to the previous
target CPU after cleaning up vector to irq mapping table. To clean up
vector to irq map on the previous target CPU safty, change the irq
migration in multiple vector domain as follows. The original idea is
from x86 interrupt management code.
- Delay vector to irq table cleanup until the interrupts are sent
to new target CPUs. By this, it is ensured that target CPU is
completely changed on the interrupt controller side.
- Even after the interrupts are sent to new target CPUs, there can
be pended interrupts remaining on the previous target CPU. So we
need to delay clearning up vector to irq table until the pended
interrupt is handled. For this, send IPI to the previous target
CPU with lower priority vector and clean up vector to irq table
in its handler.
This patch affects only to irq migration code with multiple vector
domain is enabled.

Commit bdc807871d58285737d50dc6163d0feb72cb0dc2 broke the build
for this config because the sim_defconfig selects CONFIG_HZ=250
but include/asm-ia64/param.h has an ifdef for the simulator to
force HZ to 32. So we ended up with a kernel/timeconst.h set
for HZ=250 ... which then failed the check for the right HZ
value and died with:
Drop the #ifdef magic from param.h and make force CONFIG_HZ=32
directly for the simulator.

This is base kernel patch for ptrace RSE bug. It's basically a backport
from the utrace RSE patch I sent out several weeks ago. please review.
when a thread is stopped (ptraced), debugger might change thread's user
stack (change memory directly), and we must avoid the RSE stored in
kernel to override user stack (user space's RSE is newer than kernel's
in the case). To workaround the issue, we copy kernel RSE to user RSE
before the task is stopped, so user RSE has updated data. we then copy
user RSE to kernel after the task is resummed from traced stop and
kernel will use the newer RSE to return to user.

This patchset is for the vmcoreinfo data.
The vmcoreinfo data has the minimum debugging information only for dump
filtering. makedumpfile (dump filtering command) gets it to distinguish
unnecessary pages, and makedumpfile creates a small dumpfile.
This patch:
VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always
returning the size of the struct with a given name. This change would allow
VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not
be used exclusively for typedefs.

This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.
This patch:
Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past. This is to avoid conflicts.
Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().

This is the new timerfd API as it is implemented by the following patch:
int timerfd_create(int clockid, int flags);
int timerfd_settime(int ufd, int flags,
const struct itimerspec *utmr,
struct itimerspec *otmr);
int timerfd_gettime(int ufd, struct itimerspec *otmr);
The timerfd_create() API creates an un-programmed timerfd fd. The "clockid"
parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.
The timerfd_settime() API give new settings by the timerfd fd, by optionally
retrieving the previous expiration time (in case the "otmr" parameter is not
NULL).
The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit
is set in the "flags" parameter. Otherwise it's a relative time.
The timerfd_gettime() API returns the next expiration time of the timer, or
{0, 0} if the timerfd has not been set yet.
Like the previous timerfd API implementation, read(2) and poll(2) are
supported (with the same interface). Here's a simple test program I used to
exercise the new timerfd APIs:

This requires making die() and die_if_kernel() return a value, and their
callers to honor this (and be prepared that it returns).
