| * | sh: fix R2D-1 CF supportMagnus Damm2007-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.

| * | sh: lockless UTLB miss fast-path.Paul Mundt2007-11-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the refactored update_mmu_cache() introduced in older kernels, there's no longer any need to take the page_table_lock in this path, so simply drop it completely. Without this, performance degradation is seen on SMP on heavily threaded workloads that don't use the split ptlock, and ultimately we have no reason to contend for the lock in the first place.

| * | sh: Kill off UTLB flush in fast-path.Paul Mundt2007-11-18
| |/ | | | | | | | | | | | | | | | | | | | | The __do_page_fault() fast-path contains a UTLB flush in order to force an ITLB reload, this isn't needed in practice as the ITLB is auto-reloaded from the UTLB anyways, which is already displaced by the manual 'ldtlb' in the update_mmu_cache() path. This provides a measurable speed up in the TLB miss fast-path. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current support for TRACE_IRQFLAGS and lockdep_sys_exit is broken. IRQ flag tracing is broken for program checks. Even worse is that the newly introduced calls to lockdep_sys_exit are in the critical section code which is not supposed to call any C functions. In addition the checks if locks are still held are also done when returning to kernel code which is broken as well. Fix all this by disabling interrupts and machine checks at the exit paths and then do the appropriate checks and calls.

| | * | | [POWERPC] 83xx: mpc832x mds: Fix board PHY reset codeKim Phillips2007-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | currently the board-level PHY reset code for the mpc832x MDS messes with reset configuration words source settings which is plain wrong (it looks like this board code was cut-n-pasted from the mpc8360 mds code, which has the PHY reset bits in a different BCSR); this patch points the PHY reset code to the proper mpc832x mds PHY reset bits in the BCSR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we get no user time and no system time allocated since the last account_system_vtime, the system to user time ratio estimate can end up dividing by zero. This was causing a problem noticed by Balbir Singh. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | [POWERPC] spufs: Fix context destroy vs /spu readdir raceJeremy Kerr2007-11-20

This is due to the context's top-level dentry remaining hashed while the context is being destroyed. Fix this by unhashing the context's dentry with the dentry->d_inode->i_mutex held. This way, we'll hit the check for d_unhashed in dentry_readdir, and won't be included in the list of subdirs for /spu. test: spufs-testsuite:tests/01-spu_create/07-destroy-vs-readdir-race Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | [POWERPC] Fix RTAS os-term usage on kernel panicLinas Vepstas2007-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtas_os_term() routine was being called at the wrong time. The actual rtas call "os-term" will not ever return, and so calling it from the panic notifier is too early. Instead, call it from the machine_reset() call. This splits the rtas_os_term() routine into two: one part to capture the kernel panic message, invoked during the panic notifier, and another part that is invoked during machine_reset(). Prior to this patch, the os-term call was never being made, because panic_timeout was always non-zero. Calling os-term helps keep the hypervisor happy! We have to keep the hypervisor happy to avoid service, dump and error reporting problems. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | [POWERPC] vdso: Fixes for cache block sizesOlof Johansson2007-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current VDSO implementation is hardcoded to 128 byte cache blocks, which are only used on IBM's 64-bit processors. Convert it to get the cache block sizes out of vdso_data instead, similar to how the ppc64 in-kernel cache flush does it.
