| | | | | | | | | | | The function prototypes for iosapic_enable_intr() and iosapic_pci_fixup() in include/asm-ia64/iosapic.h are no longer needed. This patch removes them.

* [IA64] minor performance tune-up in ia64_switch_toChen, Kenneth W2005-09-071-3/+3
| | | | | | | | | | The reenabling of psr.ic should really belong to dtr mapping code block. It make the fall through code fast since it doesn't need to execute the predicated-off instruction. Logically make more sense as well since psr.ic was turned off in .map code block. Signed-off-by: Ken Chen <kenneth.w.chen@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] make exception handler in copy_user more robustChen, Kenneth W2005-09-071-0/+3
| | | | | | | | | | | | | | The exception handler in copy user always expects fault occurs only on user space address and the fall back recovery code is written with that very assumption in mind. Recent source code inspection revealed that while it worked splendid and to the expectation under normal circumstances, It broke down under unexpected condition where some address calculation might go outside the legal address range the original copy_user was called for. This patch is to make copy_user exception handler more robust and to prevent potential memory corruption.

* [IA64] page_not_present fault in region 5 is normalKiyoshi Ueda2005-09-061-3/+3
| | | | | | | | | | | | | When copying data from user-space to kernel-space by __copy_user(), a page_not_present fault sometimes occurs at vmalloced kernel address because of VHPT pre-fetching. Ignore the page_not_present fault in ia64_do_page_fault() before jumping into exception handlers.

| * [PATCH] Invert sense of SLB class bitDavid Gibson2005-09-064-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we set the class bit in kernel SLB entries, and clear it on user SLB entries. On POWER5, ERAT entries created in real mode have the class bit clear. So to avoid flushing kernel ERAT entries on each context switch, this patch inverts our usage of the class bit, setting it on user SLB entries and clearing it on kernel SLB entries. Booted on POWER5 and G5. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
