2022-01-14x86/fpu: Add guest support to xfd_enable_feature()Thomas Gleixner
Guest support for dynamically enabled FPU features requires a few modifications to the enablement function which is currently invoked from the #NM handler: 1) Use guest permissions and sizes for the update 2) Update fpu_guest state accordingly 3) Take into account that the enabling can be triggered either from a running guest via XSETBV and MSR_IA32_XFD write emulation or from a guest restore. In the latter case the guests fpstate is not the current tasks active fpstate. Split the function and implement the guest mechanics throughout the callchain.

2022-01-14x86/fpu: Make XFD initialization in __fpstate_reset() a function argumentJing Liu
vCPU threads are different from native tasks regarding to the initial XFD value. While all native tasks follow a fixed value (init_fpstate::xfd) established by the FPU core at boot, vCPU threads need to obey the reset value (i.e. ZERO) defined by the specification, to meet the expectation of the guest. Let the caller supply an argument and adjust the host and guest related invocations accordingly.

2022-01-14module: fix signature check failures when using in-kernel decompressionDmitry Torokhov
The new flag MODULE_INIT_COMPRESSED_FILE unintentionally trips check in module_sig_check(). The check was supposed to catch case when version info or magic was removed from a signed module, making signature invalid, but it was coded too broadly and was catching this new flag as well. Change the check to only test the 2 particular flags affecting signature validity.

2022-01-14perf cputopo: Fix CPU topology reading on s/390Thomas Richter
Commit fdf1e29b6118c18f ("perf expr: Add metric literals for topology.") fails on s390: # ./perf test -Fv 7 ... # FAILED tests/expr.c:173 #num_dies >= #num_packages ---- end ---- Simple expression parser: FAILED! # Investigating this issue leads to these functions: build_cpu_topology() +--> has_die_topology(void) { struct utsname uts; if (uname(&uts) < 0) return false; if (strncmp(uts.machine, "x86_64", 6)) return false; .... } which always returns false on s390. The caller build_cpu_topology() checks has_die_topology() return value. On false the the struct cpu_topology::die_cpu_list is not contructed and has zero entries. This leads to the failing comparison: #num_dies >= #num_packages. s390 of course has a positive number of packages. Fix this by adding s390 architecture to support CPU die list.

2022-01-14drm/ttm: fix compilation on ARCH=umJohannes Berg
Even if it's probably not really useful, it can get selected by e.g. randconfig builds, and then failing to compile is an annoyance. Unfortunately, it's hard to fix in Kconfig, since DRM_TTM is selected by many things that don't really depend on any specific architecture, and just depend on PCI (which is indeed now available in ARCH=um via simulation/emulation). Fix this in the code instead by just ifdef'ing the relevant two lines that depend on "real X86".

2022-01-14tracing: Add ustring operation to filtering string pointersSteven Rostedt
Since referencing user space pointers is special, if the user wants to filter on a field that is a pointer to user space, then they need to specify it. Add a ".ustring" attribute to the field name for filters to state that the field is pointing to user space such that the kernel can take the appropriate action to read that pointer.

Add support for the AMD A85 FCH (Hudson D4) AHCI adapter. Since this adapter does not require the default 200 ms debounce delay in sata_link_resume(), create a new board board_ahci_no_debounce_delay with the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY, and, for now, configure the AMD A85 FCH (Hudson D4) to use it. On the ASUS F2A85-M PRO it reduces the Linux kernel boot time by the expected 200 ms from 787 ms to 585 ms.

This patch cleans up the code of __ata_scsi_queuecmd(). Since each branch of the "if" condition check that scmd->cmd_len is not zero, move this check out of the "if" to simplify the conditions being checked in the "else" branch.

2022-01-14ata: pata_of_platform: Use platform_get_irq_optional() to get the interruptLad Prabhakar
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional(). Note the code does not set the IRQ flags as this is handled automatically for DT.

2022-01-14ata: fix read_id() ata port operation interfaceDamien Le Moal
Drivers that need to tweak a device IDENTIFY data implement the read_id() port operation. The IDENTIFY data buffer is passed as an argument to the read_id() operation for drivers to use. However, when this operation is called, the IDENTIFY data is not yet converted to CPU endian and contains le16 words. Change the interface of the read_id operation to pass a __le16 * pointer to the IDENTIFY data buffer to clarify the buffer endianness. Fix the pata_netcell, pata_it821x, ahci_xgene, ahci_ceva and ahci_brcm drivers implementation of this operation and modify the code to corretly deal with identify data words manipulation to avoid sparse warnings such as: drivers/ata/ahci_xgene.c:262:33: warning: invalid assignment: &= drivers/ata/ahci_xgene.c:262:33: left side has type unsigned short drivers/ata/ahci_xgene.c:262:33: right side has type restricted __le16 Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.de>
