[PowerPC] Add JMP_SLOT relocation definitions
This will be required by upcoming patches for LLDB support.
Patch by Justin Hibbits!
Pull in r221510 from upstream llvm trunk (by Justin Hibbits):
Add Position-independent Code model Module API.
Summary:
This makes PIC levels a Module flag attribute, which can be queried by the
backend. The flag is named `PIC Level`, and can have a value of:
0 - Backend-default
1 - Small-model (-fpic)
2 - Large-model (-fPIC)
These match the `-pic-level' command line argument for clang, and the value of the
preprocessor macro `__PIC__'.
Test Plan:
New flags tests specific for the 'PIC Level' module flag.
Tests to be added as part of a future commit for PowerPC, which will use this new API.

Pull in r221791 from upstream llvm trunk (by Justin Hibbits):
Add support for small-model PIC for PowerPC.
Summary:
Large-model was added first. With the addition of support for multiple PIC
models in LLVM, now add small-model PIC for 32-bit PowerPC, SysV4 ABI. This
generates more optimal code, for shared libraries with less than about 16380
data objects.
Test Plan: Test cases added or updated

Together, these changes implement small-model PIC support for PowerPC.
Thanks to Justin Hibbits and Roman Divacky for their assistance in
getting this working.
This enables the use of GPIO pins as interrupt sources for kernel devices
directly attached to gpiobus (userland notification will be added soon).
The use of gpio interrupts for other kernel devices will be possible when
intrng is complete.
All GPIO pins can be set to trigger on:
- active-low;
- active-high;
- rising edge;
- falling edge.
Tested on: Beaglebone-black
code, passing a 0/1 flag that indicates which type of abort it was. This
sets the stage for unifying the handling of page faults in a single routine.

If it seems like this is getting out of hand, I quite agree. I wonder if
it's safe, here in the 21st century, to lose the distinction between C and
ASM symbols?

No functional changes, this is all so that the functional changes in the
next commit will stand out.
'extra' entry points which are nested within or provide a synonym name
for another function. It's most likely not safe to be messing with the
IP and LR registers at anything other than the primary entry point to a
function. Anywhere beyond initial function entry, those registers may
be in use as scratch or variable registers.

Prior to this fix "zpool upgrade" and "zpool upgrade -a" would fail due to
an assert when operating on unavailable pools.
We now print a warning to stderr but allow the processing of other pools
to procesed.

was reported via email. This was caused by a LOR between the
sleep lock used to serialize the local locking (nfsrv_locklf())
and locking the vnode. I believe this patch fixes the problem
by delaying relocking of the vnode until the sleep lock is
unlocked (nfsrv_unlocklf()). To avoid nfsvno_advlock() having the side
effect of unlocking the vnode, unlocking the vnode was moved to before
the functions that call nfsvno_advlock().
It shouldn't affect the execution of the default case where
vfs.nfsd.enable_locallocks=0.

locks/unlocks the vnode and does a VOP_GETATTR()
for the SEEK_END case. This is safe to do, since
lf_advlock{async}() only uses the size argument
for the SEEK_END case.
The NFSv4 server needs this when
vfs.nfsd.enable_locallocks!=0 since locking the
vnode results in a LOR that can cause a deadlock
for the nfsd threads.

- Eliminate unused irqframe
- Eliminate unused saframe
- Instead of splitting r4-sp storage between the stack and switchframe,
just put all the registers in switchframe and eliminate the un_32 struct.

The ARM image builds build the in-tree gcc in order to build u-boot
and gperf is needed to build gcc, but is no longer installed on archs
that use clang.
Invoking the make targets as separate steps is done to work around
a build failure which is not yet fully understood.

IPv6. Initialize it only once in def_policy_init(). Remove its
initialization from key_init() and make it static.
Remove several fields from struct secpolicy:
* lock - it isn't so useful having mutex in the structure, but the only
thing we do with it is initialization and destroying.
* state - it has only two values - DEAD and ALIVE. Instead of take a lock
and change the state to DEAD, then take lock again in GC function and
delete policy from the chain - keep in the chain only ALIVE policies.
* scangen - it was used in GC function to protect from sending several
SADB_SPDEXPIRE messages for one SPD entry. Now we don't keep DEAD entries
in the chain and there is no need to have scangen variable.
Use TAILQ to implement SPD entries chain. Use rmlock to protect access
to SPD entries chain. Protect all SP lookup with RLOCK, and use WLOCK
when we are inserting (or removing) SP entry in the chain.
Instead of using pattern "LOCK(); refcnt++; UNLOCK();", use refcount(9)
API to implement refcounting in SPD. Merge code from key_delsp() and
_key_delsp() into _key_freesp(). And use KEY_FREESP() macro in all cases
when we want to release reference or just delete SP entry.

Fix the following issues:
- Removed revision from device softc, it isn't used anywhere else out of
device attach routine;
- Move the duplicated code for verification of valid banks (and pins) to
a single function;
- Use some macros to simplify the handling of some constants;
- Update some stale comments.
Subdirectories are copied from r276062.
This will allow 'svn merge' at the elftoolchain top level to work
properly. Previously only the subdirectories were related to the vendor
branch according to svn metadata, which meant they would have to be
merged individually.
The SAMPLE message and notes where tab seperated for some parts and hence
displayed incorrectly unless tabstop was set to 8. Switch to spaces to it

AR5416 and later NICs have more than 8 (Well, more than 6) GPIO pins.
So to support rfkill on these NICs we need to bump this up or the
rfkill GPIO pin may get reset to the wrong value.

According to objcopy(1) --target is for use where the input and output
formats are the same ("no translation"). In practice it does detect the
input format in any case, but be explicit that we're specifying the
output format as we are translating from ELF to EFI PE format.
