However only 4 out of 12 hotplug drivers bother to notify the\nhotplug core with pci_hp_change_slot_info() and the hotplug core never\nmade any use of the information: There is just a single macro in\npci_hotplug_core.c, GET_STATUS(), which uses the hotplug_slot_info if\nthe driver lacks the corresponding callback in hotplug_slot_ops. The\nmacro is called when the user reads the attribute via sysfs.\n\nNow, if the callback isn\u0027t defined, the attribute isn\u0027t exposed in sysfs\nin the first place (see e.g. has_power_file()). There are only two\nsituations when the hotplug_slot_info would actually be accessed:\n\n* If the driver defines -\u003eenable_slot or -\u003edisable_slot but not\n -\u003eget_power_status.\n\n* If the driver defines -\u003eset_attention_status but not\n -\u003eget_attention_status.\n\nThere is no driver doing the former and just a single driver doing the\nlatter, namely pnv_php.c. Amend it with a -\u003eget_attention_status\ncallback. With that, the hotplug_slot_info becomes completely unused by\nthe PCI hotplug core. But a few drivers use it internally as a cache:\n\ncpcihp uses it to cache the latch_status and adapter_status.\ncpqhp uses it to cache the adapter_status.\npnv_php and rpaphp use it to cache the attention_status.\nshpchp uses it to cache all four values.\n\nAmend these drivers to cache the information in their private slot\nstruct. shpchp\u0027s slot struct already contains members to cache the\npower_status and adapter_status, so additional members are only needed\nfor the other two values. In the case of cpqphp, the cached value is\nonly accessed in a single place, so instead of caching it, read the\ncurrent value from the hardware.\n\nCaution: acpiphp, cpci, cpqhp, shpchp, asus-wmi and eeepc-laptop\npopulate the hotplug_slot_info with initial values on probe.

In this paging mode the huge-page\nPTEs are in the top-level page-table directory, where also the mirroring to\nthe user-space page-table happens. So every huge PTE exits twice, in the\nkernel and in the user page-table.\n\nThat means that accessed/dirty bits need to be fetched from two PTEs in\nthis mode to be safe, but this is not trivial to implement because it needs\nchanges to generic code just for the sake of enabling PTI with 32-bit\nlegacy paging.

The\nnice feature I rely on is that after a normal \"make\", \"make targz-pkg\"\nonly generates the tarball without having to recompile everything.\n\nThat was true until commit f28bc3c32c05 (\"tracing: Handle\nCC_FLAGS_FTRACE more accurately\"). After it, running \"make targz-pkg\"\nafter \"make\" will recompile the whole Kernel tree, making my\ndevelopment workflow much slower.\n\nThe Kernel is choosing to recompile everything because it claims the\ncommand line has changed. A diff of the .cmd files show a repeated\n-mfentry in one of the files. That is because \"make targz-pkg\" calls\n\"make modules_install\" and the environment is already populated with\nthe exported variables, CC_FLAGS_FTRACE being one of them. Then,\n-mfentry gets duplicated because it is not protected behind an ifndef\nblock, like -pg.\n\nTo complicate the problem a little bit more, architectures can define\ntheir own version CC_FLAGS_FTRACE, so our code not only has to\nconsider recursive Makefiles, but also architecture overrides.\n\nSo in this patch we move CC_FLAGS_FTRACE up and unconditionally\ndefine it to -pg. Then we let the architecture Makefiles possibly\noverride it, and finally append the extra options later. This ensures\nthe variable is always fully redefined at each invocation so recursive\nMakefiles don\u0027t keep appending, and hopefully it maintains the\nintended behavior on how architectures can override the defaults..\n\nThanks Steven Rostedt and Vasily Gorbik for the help on this\nregression.\n\nCc: Michal Marek \u003cmichal.lkml@markovi.net\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Tvrtko Ursulin \u003ctvrtko.ursulin@intel.com\u003e\nCc: linux-kbuild@vger.kernel.org\nFixes: commit f28bc3c32c05 (\"tracing: Handle CC_FLAGS_FTRACE more accurately\")\nAcked-by: Vasily Gorbik \u003cgor@linux.ibm.com\u003e\nSigned-off-by: Paulo Zanoni \u003cpaulo.r.zanoni@intel.com\u003e\nSigned-off-by: Steven Rostedt (VMware) \u003crostedt@goodmis.org\u003e\n" }, { "commit": "96eddb810b146e4d364e35f38dc11d16680c66eb", "tree": "3850745774dc68a8d5e3f9258f32c23cf7c6161a", "parents": [ "aeb5427218a72ead8be673c0fba21839d2a3bb70", "e866d3e84eb7c9588afb77604d417e8cc49fe216" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 12 06:51:27 2018 -1000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 12 06:51:27 2018 -1000" }, "message": "Merge tag \u0027riscv-for-linus-4.19-rc3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux\n\nPull RISC-V fix from Palmer Dabbelt:\n \"This contains what I hope to be the last RISC-V patch for 4.19.\n\n It fixes a bug in our initramfs support by removing some broken and\n obselete code\"\n\n* tag \u0027riscv-for-linus-4.19-rc3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux:\n riscv: Do not overwrite initrd_start and initrd_end\n" }, { "commit": "aeb5427218a72ead8be673c0fba21839d2a3bb70", "tree": "b0349ff05e162e88f036e8c770065f17f3c186bf", "parents": [ "5e335542de83558e46d28de1008a1c37d5d6679a", "c77a2fa3ff8f73d1a485e67e6f81c64823739d59" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 12 06:44:03 2018 -1000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 12 06:44:03 2018 -1000" }, "message": "Merge tag \u0027scsi-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi\n\nPull SCSI fixes from James Bottomley:\n \"Three fixes, all in drivers (qedi and iscsi target) so no wider impact\n even if the code changes are a bit extensive\"\n\n* tag \u0027scsi-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:\n scsi: qedi: Add the CRC size within iSCSI NVM image\n scsi: iscsi: target: Fix conn_ops double free\n scsi: iscsi: target: Set conn-\u003esess to NULL when iscsi_login_set_conn_values fails\n" }, { "commit": "2d204ee9d671327915260071c19350d84344e096", "tree": "d1ef8c358f51282c7fc382be90af5662872ac882", "parents": [ "56446f218af1133c802dad8e9e116f07f381846c" ], "author": { "name": "Dan Carpenter", "email": "dan.carpenter@oracle.com", "time": "Mon Sep 10 14:12:07 2018 +0300" }, "committer": { "name": "Steve French", "email": "stfrench@microsoft.com", "time": "Wed Sep 12 09:32:07 2018 -0500" }, "message": "cifs: integer overflow in in SMB2_ioctl()\n\nThe \"le32_to_cpu(rsp-\u003eOutputOffset) + *plen\" addition can overflow and\nwrap around to a smaller value which looks like it would lead to an\ninformation leak.\n\nFixes: 4a72dafa19ba (\"SMB2 FSCTL and IOCTL worker function\")\nSigned-off-by: Dan Carpenter \u003cdan.carpenter@oracle.com\u003e\nSigned-off-by: Steve French \u003cstfrench@microsoft.com\u003e\nReviewed-by: Aurelien Aptel \u003caaptel@suse.com\u003e\nCC: Stable \u003cstable@vger.kernel.org\u003e\n" }, { "commit": "56446f218af1133c802dad8e9e116f07f381846c", "tree": "1f35fa87689fcfdb7eead9d9e0b12164ce384e33", "parents": [ "8ad8aa353524d89fa2e09522f3078166ff78ec42" ], "author": { "name": "Dan Carpenter", "email": "dan.carpenter@oracle.com", "time": "Thu Sep 06 12:48:22 2018 +0300" }, "committer": { "name": "Steve French", "email": "stfrench@microsoft.com", "time": "Wed Sep 12 09:32:07 2018 -0500" }, "message": "CIFS: fix wrapping bugs in num_entries()\n\nThe problem is that \"entryptr + next_offset\" and \"entryptr + len + size\"\ncan wrap.
