A few places missed the "a" specifier for the __ex_table section. Add these so we avoid generation an additional section at link time. Latest modpost would otherwise complain like this: WARNING: vmlinux.o (__ex_table.2): section name inconsistency. (.[number]+) following section name. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. WARNING: vmlinux.o (__ex_table.4): section name inconsistency. (.[number]+) following section name. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files.

Sparc64 has a way of providing the base address for the per cpu area of the currently executing processor in a global register. Sparc64 also provides a way to calculate the address of a per cpu area from a base address instead of performing an array lookup.

The break_lock data structure and code for spinlocks is quite nasty. Not only does it double the size of a spinlock but it changes locking to a potentially less optimal trylock. Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a __raw_spin_is_contended that uses the lock data itself to determine whether there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is not set. Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to decouple it from the spinlock implementation, and make it typesafe (rwlocks do not have any need_lockbreak sites -- why do they even get bloated up with that break_lock then?).

This was caught and identified by Greg Onufer. Since we setup the 256M/4M bitmap table after taking over the trap table, it's possible for some 4M mapping to get loaded in the TLB beforhand which later will be 256M mappings. This can cause illegal TLB multiple-match conditions. Fix this by setting up the bitmap before we take over the trap table. Next, __flush_tlb_all() was not doing anything on hypervisor platforms. Fix by adding sun4v_mmu_demap_all() and calling it. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When CONFIG_BUG is turned off, the standard trick of: switch (x) { case X: ... case Y: ... default: BUG(); }; to mark impossible cases does not work because BUG() evalutes to nothing and thus GCC just sees a fallthrough code path.

Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."
