2014-05-23clk: divider: Fix table round up functionMaxime COQUELIN1-1/+1
Commit 1d9fe6b97 ("clk: divider: Fix best div calculation for power-of-two and table dividers") introduces a regression in its _table_round_up function. When the divider passed to this function is greater than the max divider available in the table, this function returns table's max divider. Problem is that it causes an infinite loop in clk_divider_bestdiv() because _next_div() will never return a value greater than maxdiv. Instead of returning table's max divider, this patch returns INT_MAX.

It is, however, a mux which can be parented by either xusb_ss_src/2 or pll_u_60M. Add the fixed-factor clock xusb_ss_div2 and put an entry in periph_clks[] for the xusb_hs_src mux.

The previous default was that the 32-bit version would take precedence and we tried to change it to the other way around and it didn't work. From Lv Zheng. - A TPM commit related to ACPI _DSM in 3.14 caused the driver to refuse to load if a specific _DSM was missing and that broke resume from system suspend on Chromebooks that require the TPM hardware to be restored to a working state during resume by the OS. Restore the old behavior to load the driver if the _DSM in question is not present, but prevent it from using the feature the _DSM is for. - ACPI AC driver conversion in 3.13 broke thermal management on at least one machine and has to be reverted. From Guenter Roeck. - Two reverts of 3.13 commits that attempted to remove the old ACPI battery interface in /proc, but turned out to break some utilities still using that interface. From Lan Tianyu. - ACPI processor driver fix to prevent acpi_processor_add() from modifying the CPU device's .offline field which leads to breakage if the initial online of the CPU fails. From Igor Mammedov. - Two intel_pstate fixes, one to take a BayTrail documentation update into account and one to avoid forcing the maximum P-state on init which causes CPU PM trouble on systems with P-states coordination when one of the CPU cores is initialized after an offline/online cycle triggered by user space. Both stable candidates, from Dirk Brandewie. - Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520 from Aaron Lu. - Two new ACPI video blacklist entries for machines shipping with Win8 that need to use native backlight so that it can be controlled in a usual way (which doesn't work otherwise due bugs in the ACPI tables) from Hans de Goede. - Two ACPI _OSI quirks for systems that need them to work correctly with Linux from Edward Lin and Hans de Goede" * tag 'pm+acpi-3.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / video: Revert native brightness quirk for ThinkPad T530 intel_pstate: remove setting P state to MAX on init ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.

2014-05-20Btrfs: send, fix incorrect ref access when using extrefsFilipe Manana1-1/+1
When running send, if an inode only has extended reference items associated to it and no regular references, send.c:get_first_ref() was incorrectly assuming the reference it found was of type BTRFS_INODE_REF_KEY due to use of the wrong key variable. This caused weird behaviour when using the found item has a regular reference, such as weird path string, and occasionally (when lucky) a crash: [ 190.600652] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC [ 190.600994] Modules linked in: btrfs xor raid6_pq binfmt_misc nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc psmouse serio_raw evbug pcspkr i2c_piix4 e1000 floppy [ 190.602565] CPU: 2 PID: 14520 Comm: btrfs Not tainted 3.13.0-fdm-btrfs-next-26+ #1 [ 190.602728] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 [ 190.602868] task: ffff8800d447c920 ti: ffff8801fa79e000 task.ti: ffff8801fa79e000 [ 190.603030] RIP: 0010:[<ffffffff813266b4>] [<ffffffff813266b4>] memcpy+0x54/0x110 [ 190.603262] RSP: 0018:ffff8801fa79f880 EFLAGS: 00010202 [ 190.603395] RAX: ffff8800d4326e3f RBX: 000000000000036a RCX: ffff880000000000 [ 190.603553] RDX: 000000000000032a RSI: ffe708844042936a RDI: ffff8800d43271a9 [ 190.603710] RBP: ffff8801fa79f8c8 R08: 00000000003a4ef0 R09: 0000000000000000 [ 190.603867] R10: 793a4ef09f000000 R11: 9f0000000053726f R12: ffff8800d43271a9 [ 190.604020] R13: 0000160000000000 R14: ffff8802110134f0 R15: 000000000000036a [ 190.604020] FS: 00007fb423d09b80(0000) GS:ffff880216200000(0000) knlGS:0000000000000000 [ 190.604020] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 190.604020] CR2: 00007fb4229d4b78 CR3: 00000001f5d76000 CR4: 00000000000006e0 [ 190.604020] Stack: [ 190.604020] ffffffffa01f4d49 ffff8801fa79f8f0 00000000000009f9 ffff8801fa79f8c8 [ 190.604020] 00000000000009f9 ffff880211013260 000000000000f971 ffff88021147dba8 [ 190.604020] 00000000000009f9 ffff8801fa79f918 ffffffffa02367f5 ffff8801fa79f928 [ 190.604020] Call Trace: [ 190.604020] [<ffffffffa01f4d49>] ? read_extent_buffer+0xb9/0x120 [btrfs] [ 190.604020] [<ffffffffa02367f5>] fs_path_add_from_extent_buffer+0x45/0x60 [btrfs] [ 190.604020] [<ffffffffa0238806>] get_first_ref+0x1f6/0x210 [btrfs] [ 190.604020] [<ffffffffa0238994>] __get_cur_name_and_parent+0x174/0x3a0 [btrfs] [ 190.604020] [<ffffffff8118df3d>] ? kmem_cache_alloc_trace+0x11d/0x1e0 [ 190.604020] [<ffffffffa0236674>] ? fs_path_alloc+0x24/0x60 [btrfs] [ 190.604020] [<ffffffffa0238c91>] get_cur_path+0xd1/0x240 [btrfs] (...)
