2022-07-11regulator: qcom_spmi: add support for PMP8074 regulatorsRobert Marko1-0/+23
PMP8074 is a companion PMIC for the Qualcomm IPQ8074 WiSoC-s. It features 5 HF-SMPS and 13 LDO regulators. HF-SMPS regulators are Buck HFS430 regulators. L1, L2 and L3 are HT_N1200_ST subtype LDO regulators. L4 is HT_N300_ST subtype LDO regulator. L5 and L6 are HT_P600 subtype LDO regulators. L7, L11, L12 and L13 are HT_P150 subtype LDO regulators. L10 is HT_P50 subtype LDO regulator. This commit adds support for all of the buck regulators and LDO-s except for L10 as I dont have documentation on its output voltage range. S3 is the CPU cluster voltage supply, S4 supplies the UBI32 NPU cores and L11 is the SDIO/eMMC I/O voltage regulator required for high speeds.

2022-07-11xen/gntdev: Ignore failure to unmap INVALID_GRANT_HANDLEDemi Marie Obenour1-2/+4
The error paths of gntdev_mmap() can call unmap_grant_pages() even though not all of the pages have been successfully mapped. This will trigger the WARN_ON()s in __unmap_grant_pages_done(). The number of warnings can be very large; I have observed thousands of lines of warnings in the systemd journal. Avoid this problem by only warning on unmapping failure if the handle being unmapped is not INVALID_GRANT_HANDLE. The handle field of any page that was not successfully mapped will be INVALID_GRANT_HANDLE, so this catches all cases where unmapping can legitimately fail.

Via the trace above, this is passed through READ_ETM4x_REG, read_sysreg_s, and finally to __mrs_s where it is string-ified and used directly in inline asm. Regardless of which compiler or compiler options determine whether a loop can or can't be unrolled, which determines whether __builtin_constant_p evaluates to true when passed an expression using a loop induction variable, it is NEVER safe to allow the preprocessor to construct inline asm like: asm volatile (".inst (0x160 + (i * 4))" : "=r"(__val)); ^ expected constant expression Instead of read_etm4x_sysreg_offset() using __builtin_constant_p(), use __is_constexpr from include/linux/const.h instead to ensure only expressions that are valid integer constant expressions get passed through to read_sysreg_s().

2022-07-11staging: r8188eu: always initialise efuse buffer with 0xffMartin Kaiser1-8/+6
If BOOT_FROM_EEPROM is set, efuse_buf is not initialised before it is passed to functions that read from it. The buffer will be filled with 0x00 in this case like all local variables. However, the parsing functions expect the buffer to be filled with 0xFF if reading eeprom/efuse data failed. Fill the buffer with 0xFF before we try to read the data. Please note that this problem existed before we started using a local buffer. Adapter->eeprompriv->efuse_eeprom_data was allocated as a part of struct adapter by a vzalloc call in rtw_usb_if1_init.

The efuse_eeprom_data array in struct eeprom_priv is used only by ReadAdapterInfo8188EU. We can remove efuse_eeprom_data and use a local buffer instead. Use EFUSE_MAP_LEN_88E as buffer size. Its value is the same as HWSET_MAX_SIZE_512. The functions that access the buffer use EFUSE_MAP_LEN_88E for its size.

The EepromOrEfuse flag in struct eeprom_priv is used only in the ReadAdapterInfo8188EU function. We can remove EepromOrEfuse from struct eeprom_priv. As the meaning of EepromOrEfuse isn't obvious, there is a macro is_boot_from_eeprom that's used for checking the value. We don't need the macro, writing the check as !(eeValue & BOOT_FROM_EEPROM) makes it clear what is checked.

2022-07-11staging: rtl8192u: Fix sleep in atomic context bug in dm_fsync_timer_callbackDuoming Zhou3-22/+20
There are sleep in atomic context bugs when dm_fsync_timer_callback is executing. The root cause is that the memory allocation functions with GFP_KERNEL or GFP_NOIO parameters are called in dm_fsync_timer_callback which is a timer handler. The call paths that could trigger bugs are shown below: (interrupt context) dm_fsync_timer_callback write_nic_byte kzalloc(sizeof(data), GFP_KERNEL); //may sleep usb_control_msg kmalloc(.., GFP_NOIO); //may sleep write_nic_dword kzalloc(sizeof(data), GFP_KERNEL); //may sleep usb_control_msg kmalloc(.., GFP_NOIO); //may sleep This patch uses delayed work to replace timer and moves the operations that may sleep into the delayed work in order to mitigate bugs.
