[patch 2/2] arch/ia64: eliminate NULL test and memset after alloc_bootmem

2008-12-01T22:18:37

From: Julia Lawall diku.dk> As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary. This was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // < at >< at > expression E; statement S; < at >< at > E = $alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\|alloc_bootmem_node\|alloc_bootmem_low_pages_node\|alloc_bootmem_pages_node$(...) ... when != E ( - BUG_ON (E == NULL); | - if (E == NULL) S ) < at >< at > expression E,E1; < at >< at > E = $alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\|alloc_bootmem_node\|alloc_bootmem_low_pages_node\|alloc_bootmem_pages_node$(...) ... when != E - memset(E,0,E1); // Signed-off-by: Julia Lawall diku.dk> Cc: "Luck, Tony" intel.com> Signed-off-by: Andrew Morton linux-foundation.

Re: [PATCH 0/5] ia64/pv_ops, xen: binary patch optimization

Isaku Yamahata — 2008-12-01T02:37:15

Hi Tony. I'd like to merge those patches and the other xen domU optimization patches at the next merge window. i.e. for 2.6.29. What do you think? I think that they are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. Although people want some twist, I believe they would be minor. thanks, On Tue, Nov 25, 2008 at 10:03:50PM +0900, Isaku Yamahata wrote:

Re: [PATCH] ia64: SN specific version of dma_get_required_mask()

John Keller — 2008-11-25T20:50:01

In the case of SN Altix, the return value (with my patch) will always be 0xffffffffffffffffull. So, your check would work. And just as the current code's ia64_platform_is("sn2") check would always return TRUE on any SN2 system, so would your proposed use of dma_get_required_mask(). However, for SN2, memory size or location cannot be inferred from the return value, as it has no affect on the returned value. As Documentation/DMA-API.txt says: "This API returns the mask that the platform requires to operate efficiently." And for SN2, this is always a 64 bit mask, irregardless of memory size, location, etc. OK, I must not be understanding something. check_crashkernel_memory() appears to be coded to handle 3 or more platforms (sn2, uv, and others). -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo< at >vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH 0/5] ia64/pv_ops, xen: binary patch optimization

Isaku Yamahata — 2008-11-25T13:03:50

This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect call into in-place execution or direct call. The first patch imports helper functions which themselves doesn't interesting things. The second patch replaces the indirect function calls with a special call written in gcc extended inline asm and introduces native methods. The third patch introduces binary patch for kernel modules. The forth patch suppress false positive warnings which were caused by the previous patches. The last patch implements xen methods. For convenience the working full source is available from http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/ branch: ia64-pv-ops-2008nov25-xen-ia64-optimized-domu-binary-patch For the status of this patch series http://wiki.xensource.com/xenwiki/XenIA64/UpstreamMerge thanks, Diffstat: arch/ia64/include/asm/intrinsics.h

[PATCH 11/13] ia64/pv_ops: move down __kernel_syscall_via_epc.

Isaku Yamahata — 2008-11-25T13:02:09

Move down __kernel_syscall_via_epc to the end of the page. We want to paravirtualize only __kernel_syscall_via_epc because it includes privileged instructions. Its paravirtualization increases its symbols size. On the other hand, each paravirtualized gate must have e symbols of same value and size to native's because the page is mapped to GATE_ADDR and GATE_ADDR + PERCPU_PAGE_SIZE and vmlinux is linked to those symbols. Later to have the same symbol size, we pads NOPs at the end of __kernel_syscall_via_epc. Move it after other functions to keep symbols of other functions have same values and sizes.
