pv_cpu_ops.getreg(_IA64_REG_IP) returned constant. But the returned ip valued should be the one in the caller, not of the callee. This patch fixes that. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>

After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.

introduce pv_cpu_ops to paravirtualize privleged instructions which are defined by ia64 intrinsics. make them indirect C function calls by introducing function tables, pv_cpu_ops.

__local_irq_save() and local_save_flags() are used to mask interruptions. They read all psr bits that requres whole bit emulation. On the other hand, reading only psr.i, the single bit, can be virtualized cheaply. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>

[IA64] pvops: preparation: introduce ia64_set_rr0_to_rr4() to make kernel paravirtualization friendly. make kernel paravirtualization friendly by introducing ia64_set_rr0_to_rr4(). ia64/Xen will replace setting rr[0-4] with single hypercall later.

Add the primitives cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64. They use cmpxchg_acq as underlying macro, just like the already existing ia64 cmpxchg(). Changelog: ia64 cmpxchg_local coding style fix Quoting Keith Owens: As a matter of coding style, I prefer #define cmpxchg_local cmpxchg #define cmpxchg64_local cmpxchg64 Which makes it absolutely clear that they are the same code. With your patch, humans have to do a string compare of two defines to see if they are the same. Note cmpxchg is *not* a performance win vs interrupt disable / enable on IA64.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
