Lastly I converted the bau over to using the uv_hub_info->m_val which is the correct value. Without this patch, booting a large configuration hits a problem where the upper bits of the gnode affect the pnode and the bau will not operate.

Replace it by preempt_enable/disable as this is sufficient for an UP machine. The ioctl can be unlocked because there is no functionality which requires serialization. The usage by multiple callers is broken with and without the BKL due to the local static variable addr.

Fixes breakage introduced by 37443ef3f0406e855e169c87ae3f4ffb4b6ff635 ("sh: Migrate SH-4 cacheflush ops to function pointers."). Without this patch configuring caches off with CONFIG_CACHE_OFF=y makes kfr2r09 and migo-r lock up in fbdev deferred io or early user space.

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently The SH-4 cache flushing code uses flush_cache_4096() for most of the real flushing work, which breaks down to a fixed 4096 unroll and increment. Not only is this sub-optimal for larger page sizes, it's also uncovered a bug in sh4_flush_dcache_page() when large page sizes are used and we have no cache aliases -- resulting in only a part of the page's D-cache lines being written back.

But the usage of irq_fpu_usable in aesni-intel_glue.c is not changed accordingly. This patch fixes this.

It currently does this by looking at the kernel function data and retrieves the TOC that way. Not only is this inefficient, it also breaks with a relocatable kernel. The PACA contains the kernel TOC and we can easily retrieve it that way. Reported-by: Sachin Sant <sachinp@in.ibm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
